How to choose AI tools for Amazon sellers

Choose the working environment first, then check what the assistant can change and what access costs. These answers summarize the sourced comparison below.

Which assistant fits the way you work?

Amazon Seller Assistant works inside Seller Central. Helium Agent works inside Helium 10, with a separate connector for your own AI client. Choose either when that is already where your team works.⁸²²

Choose Jungle Scout MCP to use Cobalt marketplace intelligence in your AI client, ZonGuru to work on listings in Helix, or Nova to ask questions of its profit, advertising and inventory data. These connections reach each vendor's data or records; check the account coverage before choosing.³³⁴⁵⁶⁰

Choose Kuudo when your own AI should work across seller operations, advertising and Vendor Central through Amazon's APIs. Choose Managed MCP or Private Cloud; the client, workspace rules and account connections are yours.⁷⁰

Compare what each AI reaches

Can the AI change your Amazon account?

Some assistants act on Amazon; others change vendor records or draft outputs for you. Check each workflow's destination and approval settings before authorizing a change.

Amazon Seller Assistant acts when you authorize it. ZonGuru's MCP writes Helix records through evaluate-and-confirm steps; that is not publication to Amazon. Nova's import tools update Nova inputs after confirmation; its pages disagree on whether listing edits to Amazon are available.¹⁴⁵⁶⁰⁶¹

Kuudo separates read and write tools. Write tools validate inputs and apply your workspace policy, which may require human approval before a change reaches Amazon. Each call records the user, agent, parameters, result and approval state.⁷⁰

Compare actions and approval limits

What is free, bundled or separately billed?

An assistant included in a paid subscription is not a free plan. Compare recurring allowances with time-limited trials, and include the cloud and AI client costs in your budget.

Helium Agent and its MCP Connector are included with Helium 10 Diamond. Jungle Scout says Catalyst has no free trial; its seven-day money-back offer requires a purchase. Nova offers a 14-day trial without a payment method, starting after the initial account import.²²²⁶⁵¹

Kuudo Community (Private Cloud) includes 10,000 free Amazon API calls per month, with one instance of each Amazon MCP server in your own cloud. This is a recurring free tier. Your cloud and AI providers bill separately; Kuudo is in private beta.⁷¹

Compare pricing and access

AI agents for Amazon sellers: what can they do?

An AI agent works through tasks using the tools and account access available to it. A seller might ask it to review a listing, summarize inventory or prepare a listing edit. Check whether it works from information you provide, a seller tool or your Amazon account, and what it can change before you approve its access.

Use ChatGPT with Seller Central

A pasted report gives an assistant that report. A connected account gives it access to the tools and data you authorize. See how to connect Seller Central to ChatGPT.

Review and optimize listings

AI listing tools can draft titles, bullets and descriptions; publication and approval vary by tool. See how the Amazon listing optimizer reviews listing data and prepares changes.

Before you buy

What to ask any vendor.

The rows above encode these questions. Ask them of every tool on a demo, including us, and write the answers down next to each other.

Where the AI lives
Where does the AI live: in Seller Central, in a vendor's product, or in the AI I already use?
Ask where you will actually meet the AI. Built into Seller Central, it goes where Amazon puts it. Built into a vendor's product, it answers inside that product. Connected to your own AI client, it sits beside the rest of your work. Each is a different habit for your team.
What it reaches
What can the AI reach: my live Amazon account, or the vendor's own data?
Ask what the AI can actually see. An assistant inside a tool sees that tool's data. An MCP into a vendor's product exposes what the vendor chose to expose, under its limits. Ask whether it reaches your live Amazon account, which accounts, and which of Amazon's APIs sit behind it.
What it can do
Can the AI take actions, or does it only draft and advise?
Ask for the list of actions the AI can take, not the list of things it can discuss. Then ask what waits for a person: whether approval is a setting you control, a fixed step, or a promise, and whether there is a record of what was done and who approved it.
Listing content
Does the AI write listing content, and who publishes it?
Ask what the AI writes from: a product description you type, the live catalog record, or competitor listings. Ask whether it checks the result against Amazon's rules for that field, whether it publishes to Amazon or hands you text to paste, and what you approve before anything changes.
Questions about your data
Can I ask the AI questions about my own account's data?
Ask whether you can put a plain-language question about your own sales, profit, advertising or inventory, and what the answer is computed from. An assistant that answers from help articles is a search box. One that answers from your account's data is an analyst.
Models and clients
Which AI does it use, and can I choose?
Ask which model or AI client is behind it, and whether that is your choice or the vendor's. Your team may already pay for and trust one assistant. Ask whether the tool works with it, or whether using the tool means adopting the vendor's AI as well.
Limits and caveats
What limits and caveats do they publish on the AI?
Ask for the limits in writing: which marketplaces and account types are eligible, which plan includes it, whether calls or usage are capped and what extra calls cost, and whether the feature is in beta. Ask what the vendor itself says about accuracy.
Creative
Can it generate listing and ad creative, images and video?
Ask what the tool generates, not what it manages. Assembling an ad from images you already have, generating a still, and producing product video are three different jobs, and the one you need decides whether creative stays a separate tool with a separate handoff.
Your data
Where does your account data end up?
Ask where your advertising data lives, whether you can land it in your own warehouse, and what the vendor may do with it. Read the terms: several let the vendor use your data in aggregate to improve their service, and most give no retention period.
Where it runs
Where does it run?
Ask who operates the service, what you retain, and how you can change deployment. Kuudo offers Managed MCP for velocity and Private Cloud for infrastructure control, with the same ownership principles and freedom to move between them.
Approval
What happens before anything changes on Amazon?
Ask which writes to your account can be gated on a person's approval and which cannot. Most tools gate rules and harvesting but not the engine's own bid changes. Ask to see the approval step on a demo, not the slide about it.
Pricing model
How is it priced?
Ask for the number, then ask what it is a percentage of. Percentage-of-spend pricing rises with your budget whether or not the tool earned it, and several vendors publish no price at all. Ask what happens to your campaigns on the day you cancel.

Their fit

Choose a built-in or bundled assistant if

Real situations where a built-in or bundled assistant is the better buy. If one of them is yours, buy one, and use the rows above to pick which.

You want AI that costs nothing and is already in front of you.
Amazon's Seller Assistant is free to use and sits inside Seller Central, where your team already works, and its plugin, in beta, brings it into Amazon Quick and Claude. Amazon also offers primary account holders a free 12-month Amazon Quick Plus subscription through December 31, 2026. It answers from Seller Central resources with source links, reads your account's sales and inventory figures, and can act with your permission. Kuudo Community (Private Cloud) is free too, but it is a connection your team runs in its own cloud. If free and built in is the requirement, Amazon's assistant meets it.
Your team's day happens inside Seller Central.
Seller Assistant lives where the work is: it investigates an inactive listing, helps resolve stranded inventory and opens a support case from the same screen, and its answers cite Amazon's own help pages. Kuudo brings Amazon to the AI client your team uses. If the habit is Seller Central, the assistant inside it fits the habit.
You already pay for a suite, and its AI comes with the plan.
Helium 10 includes Helium Agent and its connector with the Diamond plan, alongside the research, keyword and inventory tools a team may already use daily, and Nova's connector comes with its profit analytics. If the suite is where your numbers already live, an assistant that answers from that suite is the short path.

Our fit

Choose Kuudo if

Where Kuudo fits: connect your AI client to Amazon across seller, advertising and vendor work, through Managed MCP or Private Cloud.

The whole Amazon job
You want one AI for the whole Amazon job, not one per screen.
Selling Partner: 341 operations for orders, inventory, pricing, catalog and reports. Amazon Ads: 756 operations across 55 services, including Amazon Marketing Cloud. Vendor Central: 42 operations, including Retail Analytics. Amazon's own AI is split by account, Seller Assistant and its plugin on the selling account and Amazon Ads Agent on the ads account, and a vendor's AI answers from the vendor's product. Beyond AI tools, the same agent runs advertising, Amazon Marketing Cloud, vendor work and creative.
Your AI client
The AI you already use should be the one that works on Amazon.
Kuudo connects to Claude, Claude Desktop, Claude Cowork, Claude Code, ChatGPT, Codex, Cursor, Gemini, n8n, Make, Activepieces and any other client that speaks Model Context Protocol. Seller Assistant runs on the models Amazon chose, and its plugin reaches two AI clients so far, Amazon Quick and Claude. Where a vendor on this page ships an MCP, it points at the vendor's product. Kuudo's point at Amazon, so your assistant reads your live listings, orders and fees, and the model stays your choice.
Your rules
Your rules, your logic: read the Skill before it runs, and write the next one.
20 Skills (2 Kuudo-certified) state the job each one does, the inputs it needs, the outputs it returns and the limits it keeps, and you write your own in the same format. Amazon publishes the skills its plugin uses, and Seller Assistant workflows start from a plain-language request and guardrails you set. A prompt library tells an assistant what to ask. A Skill tells it how your business does the job, and Agent Atlas supplies the Amazon operating knowledge it reads before it acts.
Ownership
Choose who runs the service. Private. Trusted. Owned.
Choose Managed MCP, operated by Kuudo, or Private Cloud in your own AWS, GCP, Azure or Cloudflare account. In Private Cloud, Agent Flow lands your Ads and Selling Partner data in a data lake there for your warehouse and BI tools. Kuudo Pro (Private Cloud) is $0 a month plus $0.95 per 1,000 Amazon API calls, and Kuudo Scale (Private Cloud) is $249 a month plus $0.55 per 1,000 Amazon API calls.
Control
What the AI may do on your account is a policy you wrote.
Every tool is tagged read or write. Read tools return data only. Write tools validate the input, apply your workspace policy, and may require a person's approval before a change reaches Amazon, and every call is recorded with the user, the agent, the parameters and the approval state in a run log. Amazon's workflows and plugin also wait for your approval and keep an audit trail, so on control the two are close. Here one policy you write covers Ads, Selling Partner and Vendor Central.

Row by row

Every row, tool by tool.

The long form of every cell in the table above: what each tool does at each step of the AI job on Amazon, then on everything else you get and how you buy it, in its own words where its pages give them, with the source and the date.

Where the AI lives

Where does the AI live: in Seller Central, in a vendor's product, or in the AI I already use?

AI for an Amazon seller lives in the tool's own app, in your own AI client, or in both. Amazon's Seller Assistant lives inside Seller Central, and its selling partner plugin, in beta, brings it into Amazon Quick and Claude. Helium Agent is built into the Helium 10 dashboard, with an MCP connector beside it. Jungle Scout, ZonGuru and Nova put the AI in your own client through an MCP, naming Claude and ChatGPT among others. Kuudo connects the assistant your team already uses to Amazon.

Amazon Seller Assistant: Amazon's September 23, 2026 article describes Seller Assistant working "inside Seller Central" and a new selling partner plugin that "brings Seller Assistant's intelligence into the AI tools sellers already use, launching first with Amazon Quick and in beta with Anthropic's Claude", "with more integrations to follow". It says the plugin "is now available in beta for sellers in Amazon's U.S. stores, with international expansion to follow."⁸
Helium 10: The Helium Agent page describes "an AI assistant built inside Helium 10", "built right into the Helium 10 dashboard", and a separate MCP Connector "for builders who want to wire Helium 10's data into their own AI workflows (Claude, custom agents, etc.)". It says both are included with the Diamond plan.²²
Jungle Scout: The help center platform guide lists Catalyst and Cobalt as web platforms and Jungle Scout MCP as accessed "through your AI tool (Claude, ChatGPT, Gemini, Copilot, and more)". The same guide lists Listing Builder and Listing Analyzer under Catalyst and marks listing tools "Not available" for Cobalt and MCP.³⁴
ZonGuru: ZonGuru's MCP post puts the AI in the seller's own assistant: a connection string copied from Helix, its listing-engineering platform, is pasted into Claude or ChatGPT. Helix shows steps for Claude Desktop, Claude.ai, Claude Code and ChatGPT, plus a manual config for any other MCP client. The post describes no assistant inside Seller Central.⁴⁵
Nova: The MCP server page presents Nova MCP as a remote server the seller adds as a custom connector in Claude (desktop app, Code and claude.ai), and says the same server URL works in ChatGPT, Gemini and Cursor through that assistant's connectors settings. The page describes no assistant inside Seller Central.⁵⁹
Kuudo: In your AI client. Kuudo's MCP servers connect the assistant your team already uses to Amazon, so the work happens in that conversation. Your team manages account connections and service access separately.⁷⁰

What it reaches

What can the AI reach: my live Amazon account, or the vendor's own data?

This row decides what the others can mean. Seller Assistant reads your Seller Central account and business data. The four vendor MCPs each reach the vendor's product: Helium 10's reads your Helium 10 data, Jungle Scout's reaches Cobalt's marketplace intelligence, ZonGuru's reaches Helix records, and Nova's reaches Nova's data model built from Amazon's APIs. Kuudo's MCP servers expose Amazon's own API operations for Ads, Selling Partner and Vendor Central, with no Kuudo database between the agent and Amazon.

Amazon Seller Assistant: The help page says responses come from a large language model "accessing information across Seller Central, including details of your account and business data". A footnote adds: "Your confidential account data is only used to answer your specific account questions."¹
Helium 10: An MCP to Helium 10. The Getting Started help article says it connects "your Helium 10 account" to AI tools and can "Read all your Helium 10 data" across Amazon, Walmart and TikTok Shop. Their pages disagree on the tool count: "40+ MCP tools" on the MCP product page, "118 tools across 22 functional categories" in the Getting Started article, and "all 89 available tools" in the Ads Write article. They disagree on accounts too: the product page says several Amazon accounts come "through a single connection", and the Getting Started article says "each connection = one account".²³²¹²⁴
Jungle Scout: An MCP to Jungle Scout: the MCP page says it connects Cobalt's Amazon marketplace intelligence to approved AI platforms. Depending on the Cobalt subscription and data access, it lists market share and category growth, brands and sellers, products and ASINs, pricing, keywords and share of voice, product attributes, brand performance, and "connected sales and advertising data, where available".³³
ZonGuru: An MCP to Helix at a URL personalized to the account under helix-api.zonguru.com. Its 17 read-only tools cover sales, fees, products, brand records, transformations and an inbox. Amazon data arrives through Amazon Connections, authorized once on Amazon's login page. The post says the assistant "works on engineered content inside Helix", not on live Amazon listings.⁴⁵
Nova: An MCP to Nova. The AI agents page says Nova MCP exposes Nova's pre-modeled Amazon schema (profit, ads, inventory, catalog) to the assistant: 500+ metrics built from SP-API and Ads API data, refreshed hourly across 23 marketplaces. Unclear from the tool reference how many tools there are: it says "37 tools" and names 21. Credentials are scoped to an isolated database dedicated to the account and can be revoked.⁶¹⁶⁰
Kuudo: Your live Amazon accounts, through Amazon's own API operations. Your AI works inside your Ads account through the Amazon Ads MCP, inside Seller Central through the Amazon Selling Partner MCP, and inside Vendor Central through the Amazon Vendor Central MCP. No Kuudo database sits between the agent and Amazon.⁷⁰

What it can do

Can the AI take actions, or does it only draft and advise?

Ask for the list of actions, then read what waits for a person. Amazon says Seller Assistant acts with your permission, on listings, stranded inventory and support cases. Helium 10's MCP changes ads after you approve each batch by default, and its help article warns that changed approval settings in Claude or ChatGPT may skip the prompt. ZonGuru's writes change Helix records in two steps, not live listings. Nova's pages disagree on listings: its tool reference says they stay as set, and its AI agents page describes listing edits a workspace owner turns on. Jungle Scout's page names no change to an Amazon account. Kuudo's write tools are guarded by your policy, and each call is recorded with its approval state.

Amazon Seller Assistant: The help page says "With your permission, Seller Assistant can also take actions on your behalf". It lists investigating inactive or blocked listings, helping resolve stranded inventory, analyzing storage fees, assessing Featured Offer eligibility, identifying compliance violations, and creating and submitting support cases, with actions taken "when you authorize it to do so".¹
Helium 10: Through the MCP, a connected AI client can change budgets, bids, campaign states, keywords, targets, negatives and portfolios and create campaigns on Amazon and Walmart ads, not delete. The Ads Write article says "Every single change requires your explicit approval", in batches of up to 20 actions, and warns that changed approval settings in Claude or ChatGPT may skip the prompt. Unclear from the Getting Started article whether the MCP writes listings: its tool list includes sync_listing_to_amazon, which pushes listing content "directly to Amazon seller account", and its list of what the MCP cannot do includes "Write to Seller Central, Walmart Seller Center, or TikTok Shop directly".²⁴²³
Jungle Scout: The MCP page says "most teams use the MCP to pull data and surface insights" and that, connected to an agentic tool like Claude Cowork, it can "execute the next step": drafting a brief, updating a tracker, flagging an anomaly. The page names no change to an Amazon account and no approval step.³³
ZonGuru: The post lists 25 write tools that "operate on your Helix records - brands, products, transformations" through two-step flows: Evaluate product edit shows the suggestion and Confirm product edit commits it. Claude's permission screen lets the seller allow or hold back each tool. "Nothing publishes to your live Amazon listings without you."⁴⁵
Nova: The tool reference lists seven import tools that write cost of goods, FBM shipping rates, VAT categories, stock parameters, supplier orders, external stock and product tags to the seller's Nova inputs, not to Seller Central. Each one "previews the change first and writes only once you confirm". Their pages disagree on listings: the tool reference answers "No" to "Can any of these tools change my Amazon account?" and says listings "stay exactly as you set them", while the AI agents page says listing edits, once a workspace owner turns them on, are "previewed and confirmed before it reaches Amazon", and lists listing optimization under "Coming soon".⁶⁰⁶¹
Kuudo: It can act. Every tool is tagged read or write. Read tools return data only. Write tools validate input, apply your workspace policy, and may require explicit human approval before a change reaches Amazon. Every call records the user, agent, parameters, result and approval state in a run log.⁷⁰

Listing content

Does the AI write listing content, and who publishes it?

Each column writes listing text of some kind, and the question is who publishes it. Amazon's generative tools draft titles, bullets and descriptions that you review, edit and approve before submitting. Helium 10's Listing Builder skill publishes to Amazon or exports. Jungle Scout's AI Assist writes copy a person accepts or discards, ZonGuru's Helix output is copied or exported as a CSV, and Nova's free title rewriter returns text. Kuudo's Listing Optimizer reads the live catalog record, rewrites against Amazon's limits, previews the change, and writes it on your approval.

Amazon Seller Assistant: Amazon's Nov 3, 2025 blog says generative AI in Add Products creates titles, bullet points and descriptions from a few words, up to three images, a web URL or a spreadsheet, and A+ Content Manager generates text and images. Sellers "review, edit, and approve the listing" before submitting it.⁵
Helium 10: The help center's Listing Builder Skill in Helium Agent takes up to 5 product images, keyword sources and competitor ASINs, and generates a title, bullets and description that the seller can edit, then "Publish directly to Amazon or export for later". For an existing listing it rewrites one field and publishes it back, which requires a seller SKU. The same article calls Helium Agent "read-only by design" and answers "No" to "Can Helium Agent change my campaigns, bids, or budgets?", describing it as "Analysis only".²⁵
Jungle Scout: The help center says AI Assist in Listing Builder takes the top keywords from the keyword bank and "leverages Open AI's model" to generate the product title, five features and description. The user reviews each result and chooses Discard or Replace, then can edit the text. The article does not mention images, A+ Content or publishing.³⁶
ZonGuru: A Helix transformation produces an engineered title, bullets and description from a guided submission of the ASIN, brand guidelines, positioning and differentiators, plus niche research. A guided validation has the seller review brand and product details before it is finalized. Output is copied from the Helix app or exported as a formatted CSV for Seller Central.⁴⁶
Nova: The free title optimizer page says the seller pastes an ASIN, Nova fetches the live title, brand, category and attributes from Amazon, and "Nova's Amazon-tuned AI model" plus a 7-rule validator returns a title of 75 characters or fewer, a compliance checklist and a kept-versus-dropped list. The page describes no publishing to Amazon.⁶²
Kuudo: Yes. Amazon Listing Optimizer reads the live catalog and your submitted listing, finds suppressions, contradictions and thin copy, rewrites titles, bullets and search terms against Amazon's limits, and writes approved changes to the live listing. Every change is previewed first and waits for your approval.⁶⁹

Questions about your data

Can I ask the AI questions about my own account's data?

Four of the five answer plain-language questions from account data: Seller Assistant from Amazon's own figures, Helium Agent from live Helium 10 data, ZonGuru from sales, traffic and fee history in Helix, and Nova from your Nova account with 24 months of history. Jungle Scout's chat is in early beta and describes its answers as coming from YouTube transcripts, its blog and its help center. Kuudo runs a governed query on your own delivered Amazon data and returns a table with its lineage.

Amazon Seller Assistant: The help page lists questions such as "What were my sales in the last quarter?" and "What is my current inventory health?". It says sellers can retrieve sales data and page views, and the assistant summarizes recent sales and units sold compared with the previous year, using Amazon data.¹
Helium 10: The Helium Agent page says it answers questions "using your live account data" across ads, keywords, P&L, listings and inventory "in a single conversational interface". It lists what it reads: Helium 10 Ads campaign performance, Keyword Tracker ranking history, Profits net margin per ASIN, Inventory Management levels and Listing Analyzer health scores.²²
Jungle Scout: The AI Assist Chat article says Starter and Growth Accelerator customers can ask "Knowledge and Support Questions" and all other customers can also ask "tailored questions related to your Business". Unclear from the article what a business answer draws on: it says the chat has access to help center articles, blog posts and select YouTube transcripts, and it names no account data. It gives no source links and says the chat "is in early beta and may produce inaccurate results".³⁵
ZonGuru: Through the Helix connection the seller asks in plain language, for example which listings have high sessions but weak conversions. Answers draw on sales, traffic and fee history imported through Amazon Connections, plus Helix brand and product records. The post sends ads questions to Amazon's own Ads MCP Server and names no inventory or profit tool.⁴⁵
Nova: The tool reference says "You ask a question in plain language and the assistant picks the tool". Its query tools answer from the seller's own Nova account on profit and movers, advertising, search terms, Search Query Performance, BSR, inventory and listing health, with 24 months of history queryable and a 30-minute refresh on money metrics.⁶⁰
Kuudo: Yes. You ask in plain language, for example which SKUs drove the most revenue in the last 30 days. The assistant runs a governed query on your delivered Amazon data, analyzes the result in a sandbox, and returns a bounded table with its lineage. Read-only SQL is also available.⁶⁷

Models and clients

Which AI does it use, and can I choose?

Amazon says Seller Assistant is built on Amazon Bedrock with Anthropic's Claude models, and its plugin lets a seller reach it from Amazon Quick or, in beta, Claude. ZonGuru names ChatGPT-4 for its Listing Optimizer, and Jungle Scout's listing AI names Open AI's model. For their MCPs, Helium 10, Jungle Scout and Nova let you bring your own client, and Nova says to bring your own Claude account. Kuudo connects whichever MCP client you choose, so the model is yours to pick and to change.

Amazon Seller Assistant: Amazon's September 23, 2026 article says Seller Assistant is "Built on Amazon Bedrock with Anthropic's Claude models" and describes no way to choose the model inside Seller Central. Its selling partner plugin brings Seller Assistant into Amazon Quick and, in beta, Anthropic's Claude.⁸
Helium 10: For the MCP, the help center says "Any MCP-compatible client works. Currently tested and supported: Claude (Web & Desktop), ChatGPT, and Codex." The seller picks the client, and the article advises "Use Sonnet or Opus; avoid Haiku or Instant". The article does not name a model behind Helium 10's own AI features.²³
Jungle Scout: The MCP page says Jungle Scout MCP is designed to work with AI platforms that support MCP connections, "including tools such as Claude, ChatGPT, Gemini, Copilot, and approved custom or internal AI environments", and that availability and functionality may vary by platform and organizational configuration. It also names Claude Cowork as an agentic tool.³³
ZonGuru: The Listing Optimizer page says the tool is "Backed by ChatGPT-4" and uses it to find keywords and auto-generate or rewrite product listings, with seller instructions on tone, brand personality, format and language. The page describes no option to pick a different model, and it does not mention Helix or an MCP connection.⁴⁷
Nova: The AI agents page says any assistant that speaks the Model Context Protocol can connect and names Claude (Claude Desktop, Claude Code), ChatGPT, Gemini and Cursor. It says "Bring your own Claude account" and that Nova provides the data layer and the MCP connection. The page names no AI model run by Nova itself.⁶¹
Kuudo: Your choice. Kuudo connects Claude, ChatGPT, Cursor, Copilot, n8n, or any MCP client, so the model is the one your team already uses and can change. Kuudo does not put an assistant of its own between you and Amazon.⁷¹

Limits and caveats

What limits and caveats do they publish on the AI?

Each column publishes a limit or a caveat, ours included. Amazon says its AI is experimental and can make mistakes, on a page that applies to selling in the United States. Helium 10 needs the Diamond plan and includes 1,000 calls a month. Jungle Scout caps AI Assist at 50 or 300 clicks a month by plan. ZonGuru's Helix supports the United States and United Kingdom and unlocks with one $49 credit. Nova's terms allow a call cap during the trial and say outputs may be inaccurate. Kuudo is in private beta.

Amazon Seller Assistant: The help page, marked as applying to selling in the United States, says "AI is experimental and can make mistakes" and recommends verifying answers through the source links. It says not to rely on the tool for professional, legal, or financial advice. The Seller Assistant user permission affects the depth of responses.¹
Helium 10: The MCP help article requires a Diamond plan or higher and includes 1,000 API calls monthly, shared between the main account and sub-users; a $50 top-up adds 500 calls per month. It covers 13 Amazon marketplaces and the US for Walmart and TikTok Shop. Ads access requires Managed mode, which carries a 2% fee on advertising spend. Their pages disagree on freshness: the article lists "Get real-time data (data refreshes periodically, 5–15 second response times)" among what the MCP cannot do, while the MCP product page says "Leverage real-time data".²³²¹
Jungle Scout: The AI Assist in Listing Builder article says Growth Accelerator (formerly Suite) customers can click the AI Assist button up to 50 times monthly and Brand Owner (formerly Pro) subscribers up to 300. Users accept terms in a welcome message first, and the button is disabled when the keyword bank is empty.³⁶
ZonGuru: The post says Helix "currently supports the US and UK marketplaces, with more in development". The MCP connection unlocks once at least one credit sits on the account; a single credit is $49, with no subscription. Its stated caveat: "a thin brand record still produces thin verdicts". It publishes no call cap or beta label.⁴⁵
Nova: The terms say MCP use requires an active trial or subscription, the 14-day trial "may include usage limits, such as a maximum number of Nova MCP Connector calls", and any "unlimited" usage is subject to fair use and rate limits. Outputs "may be inaccurate, incomplete, outdated or wrongly interpreted", and account actions are beta features unless Nova states otherwise.⁶³
Kuudo: Kuudo is in private beta, and access starts with a request. Kuudo Community (Private Cloud) includes 10,000 free Amazon API calls per month, with one instance of each Amazon MCP server in your own cloud. Private Cloud paid plans are priced per Amazon API call; ask Kuudo for Managed MCP terms. Amazon's own permissions, marketplaces and API limits still apply.⁷¹

Amazon Ads

Can it run my Amazon Ads?

Amazon has its own answer here: Amazon Ads Agent, its renamed ad platform, has a conversational experience in closed beta that applies keyword, bid and budget recommendations once you approve the changes. Helium 10 automates bids by rules, ZonGuru reports ad spend, Nova reads ads and changes nothing today, and Jungle Scout keeps PPC management on Cobalt. Kuudo's Amazon Ads MCP carries 756 operations across Sponsored Products, Brands, Display and TV, DSP and Amazon Marketing Cloud.

Amazon Seller Assistant: Amazon Ads Agent is "the new name of the unified platform" that brings sponsored ads and Amazon DSP together (September 29, 2026). Its conversational experience turns a media plan into Display, Video, and Audio campaigns and, for sponsored ads, applies keyword, bid, and budget recommendations; the page says advertisers "review a summary of proposed changes and approve them before they're applied". It says the experience "is in closed beta", with availability varying by eligibility, marketplace, language, and capacity.⁶²
Helium 10: The Helium 10 Ads page lists bid rules, keyword harvesting, negative targeting, dayparting, budget rules and keyword rank rules that the seller defines and Helium 10 executes around the clock. It also describes AI Advertising that manages a campaign from a product, goals and a daily budget, plus expert rule templates.¹¹
Jungle Scout: The pricing page's product comparison marks PPC management, bid optimization, dayparting, rules automation, DSP management and reporting, budget control and keyword harvesting as available in the enterprise Cobalt column and not in the column for companies selling less than $1M. It does not say whether bidding is rule-based or algorithmic.²⁹
ZonGuru: Business Dashboard reports Sponsored and Product ad spend with ACOS and ACOTS. No ZonGuru page describes a tool that creates or changes campaigns, bids or budgets; this page describes reporting only.⁴⁴
Nova: The PPC page FAQ says Nova reads Amazon Ads data and changes nothing in the account today. It says managing bids and campaigns from an AI assistant is coming soon, and its comparison table lists automated bid changes as coming soon. It describes no bidding rules or algorithm.⁵⁶
Kuudo: Yes. 756 Amazon Ads operations across Sponsored Products, Brands, Display, and TV, plus DSP and Amazon Marketing Cloud, through the Amazon Ads MCP.⁶⁴

Amazon Marketing Cloud

Can it query Amazon Marketing Cloud?

Amazon's Ads Agent in AMC generates Amazon Marketing Cloud SQL from conversation and creates audience segments, and Amazon's conversational experience page says it is in closed beta. Helium 10 shows a templated Amazon Marketing Cloud dashboard in its ads tool. Jungle Scout, ZonGuru and Nova describe nothing on it. Kuudo runs queries and audiences through the Amazon Ads MCP, and the Turn AMC Questions Into Answers and Audiences Skill returns validated SQL and a segment ready to activate.

Amazon Seller Assistant: The conversational experience page says advertisers can "ask in plain language to generate SQL queries in Amazon Marketing Cloud (AMC)", and the Amazon Marketing Cloud page says Ads Agent in AMC also creates audience segments and gives product support. The conversational experience is in closed beta. Neither page mentions Seller Assistant.⁶³
Helium 10: Helium 10 Ads has an AMC page. The seller creates an Amazon Marketing Cloud instance from Ads settings, and the page shows templated views: an awareness-to-loyalty funnel, ad type overlap, new-to-brand by ASIN and ad type conversion. The article does not describe writing custom AMC queries.¹³
Jungle Scout: No page mentions Amazon Marketing Cloud. The pricing comparison lists DSP management and reporting as a Cobalt feature, and a help center search for Marketing Cloud returns no article about it.²⁹
ZonGuru: No ZonGuru page describes Amazon Marketing Cloud access. The all-features page lists thirteen tools across product research, listing optimization, business metrics, monitoring and alerts, and customer engagement, and none queries Amazon Marketing Cloud.⁴¹
Nova: No Nova page describes querying Amazon Marketing Cloud. The MCP server page lists its data sources as the Amazon SP-API, the Amazon Advertising API, Vendor Central (1P) and the customer's own cost and tag data, and its metric categories do not include Amazon Marketing Cloud.⁴⁸
Kuudo: Yes. Amazon Marketing Cloud queries and audiences run through the Amazon Ads MCP, and the Turn AMC Questions Into Answers and Audiences Skill returns validated SQL, privacy-safe results, and a segment ready to activate in DSP.⁷²

Vendor Central

Can it run Vendor Central work?

Vendors are mostly left out. No Amazon page read describes Seller Assistant working in Vendor Central, Helium 10 links seller accounts only, Jungle Scout keeps Vendor Central on Cobalt, and ZonGuru publishes nothing for vendors. Nova is the exception and says Vendor Central support is live. Kuudo's Amazon Vendor Central MCP carries 42 operations for purchase orders, direct fulfillment, shipments, invoices and Retail Analytics.

Amazon Seller Assistant: No Amazon page read describes Seller Assistant working in Vendor Central. The help page addresses sellers and describes the assistant as working in Seller Central; it does not mention Vendor Central or vendors.¹
Helium 10: The Helium 10 Ads FAQ says vendor accounts can appear to be linked to a Helium 10 account, but Helium 10 only supports seller accounts. No Helium 10 page describes a Vendor Central tool.¹²
Jungle Scout: The help center states Catalyst integrates with Amazon Seller Central accounts only and does not support Vendor Central. Cobalt, the enterprise product, supports both Seller Central and Vendor Central accounts.³⁰
ZonGuru: No ZonGuru page describes Vendor Central work. The pricing page offers Researcher, Seller and Enterprise plans, the Seller plan connects Seller Central, and Seller pricing scales on the number of active SKUs in the past 90 days.³⁷
Nova: The Vendor Central page says 1P support is live and out of beta, with multiple Seller Central and Vendor Central connections in one workspace, account switching and consolidated reporting. Vendor Central data is described as going live on the assistant connection. Connections are set up together with the Nova team.⁵⁷
Kuudo: Yes. 42 Vendor Central operations: purchase orders, direct fulfillment, shipments and invoices, and Retail Analytics, through the Amazon Vendor Central MCP.⁷⁰

Creative

Can it generate listing and ad creative, images and video?

Amazon is strong here. Its Creative Studio tool, in beta, produces video and display ads with scripts, images, animation, voiceovers and music at no additional cost, and its listing tools generate A+ Content text and images. Helium 10 generates AI images, per a help article, Jungle Scout generates listing text and describes no image or video generation, ZonGuru recommends changes to an image carousel, and Nova offers a title rewriter. Kuudo's Agent Iris generates listing images and product video, audits an image against listing rules, and publishes to the listing.

Amazon Seller Assistant: Amazon Ads' September 17, 2025 news page says an agentic AI tool in Creative Studio, in beta, produces video and display ads for Amazon DSP, Sponsored Display, Sponsored Brands and Brand Stores, including scripts, images, animation, voiceovers and music, "at no additional cost". It uses Amazon Nova and Anthropic Claude on Amazon Bedrock.⁷
Helium 10: The help center says Listing Builder's AI image generator creates main images, Amazon Post images, A+ content images, mobile-optimized images and seasonal images from a prompt and style settings. The seller downloads the image and uploads it to the Amazon listing. No Helium 10 page describes video generation.¹⁴
Jungle Scout: AI Assist in Listing Builder uses OpenAI's model and the top keywords from the keyword bank to generate the product title, all five features and the description, which the user can discard or replace. The article does not mention generating images, video or ad creative.²⁸
ZonGuru: Helix evaluates the image carousel and gives specific recommendations for what images to have and their sequence, alongside the rewritten title, bullets and description. The page does not describe Helix generating images or video.³⁸
Nova: No Nova page describes generating listing or ad images or video. Nova publishes a free title optimizer that takes an ASIN and returns a rewritten product title checked against Amazon's 75-character title rule. That page describes text rewrites only.⁵⁸
Kuudo: Yes. Agent Iris generates and audits listing images, and creates, edits, or extends owned product videos with Google Gemini Omni. Approved images publish through the Selling Partner MCP with ingestion checks; video assembly and final upload remain external. Video returns through signed download URLs.⁶⁸

Playbooks

Does it come with playbooks, and can I write my own?

Amazon publishes the skills its plugin uses, covering seller analytics, inventory, FBA inbound, listings, support cases and Selling Partner API knowledge, and a seller writes Seller Assistant workflows in plain language. Helium 10 offers four free skill files for Claude, ZonGuru publishes prompt templates it calls controllers, Nova publishes a prompt library, and Jungle Scout publishes nothing. Kuudo's 20 Skills (2 Kuudo-certified) each state the job, the inputs, the outputs and what the Skill is not for, and you write your own in the same format.

Amazon Seller Assistant: Amazon's published skills for the selling partner plugin cover seller analytics, stockout prevention, FBA inbound management, listing troubleshooting, listing issues, buyability, searchability and compliance, inviting secondary users, support cases and Selling Partner API knowledge, with three commands.⁹
Helium 10: Helium 10 publishes four free skill files for Claude: Keyword Opportunity Finder, Listing Analyzer, Brand Analytics Keywords and Search Query Performance. The user uploads a file to Claude, and live data needs a Helium 10 connection on Diamond or higher. The page does not say whether the files can be edited.¹⁵
Jungle Scout: No Catalyst page mentions playbooks, workflows or user-written rules. The plan comparison lists Review Automation with Exclusions and Delayed Send as the automation settings, and nothing the seller can author or edit as a workflow.²⁶
ZonGuru: ZonGuru's MCP post describes controllers: reusable prompt templates, one per job, that the customer pastes into a chat or stores in a Claude or ChatGPT project's instructions. The post names six jobs to run on connecting. It does not describe an editable workflow library inside ZonGuru.⁴²
Nova: Nova publishes a prompt library, written for Claude and described as working the same in ChatGPT, Gemini and other MCP-capable clients; users copy a prompt into their own assistant. Their pages disagree on its size: "35 prompts" in 7 groups on the library page, and "32 copy-and-paste prompts" on the MCP server page. The library page describes no workflow format that users author or store inside Nova.⁴⁹⁵⁹
Kuudo: 20 Skills (2 Kuudo-certified) for Amazon Ads and seller work, each publishing what it is not for, and you can write your own in the same format.⁷²

Operating knowledge

Does it bring Amazon know-how to the job?

Amazon's assistant answers from Seller Central resources with source links, and its page says it is aware of recent changes on Seller News and the help pages. The vendors teach people: Helium 10 through training and academies, Jungle Scout through an in-app Academy, ZonGuru through a weekly live academy, and Nova through guides and news briefings. Agent Atlas supplies curated Amazon operating playbooks and rules that your agent retrieves before it acts.

Amazon Seller Assistant: The help page says sellers receive "relevant, summarized information learned from Seller Central resources" with source links in the answers. It says Seller Assistant "is aware of recent changes on the Seller News and Seller Central help pages" for time-sensitive policy questions.¹
Helium 10: The pricing page lists Amazon FBA training, an Amazon Ads academy and a TikTok Shop academy under Platinum. Diamond adds monthly workshops and Q&A sessions, expert webinars and Helium, an AI agent described as keyword, listing, ads and operations intelligence in one conversation.¹⁰
Jungle Scout: The Jungle Scout Training Academy is an in-app resource for active subscribers. It holds tutorials for each feature, an A-Z course on how to sell on Amazon, advanced training videos from Jungle Scout's experts, interviews with industry experts, and webinar replays.³¹
ZonGuru: The pricing page says members unlock weekly live academy sessions and recordings, case studies and product research materials, and that 24/7 chat support is staffed by actual Amazon sellers. Enterprise adds agency training and certification.³⁷
Nova: The resources page lists a blog of 130+ guides on FBA, analytics, PPC, fees and data, 150+ news briefings on Amazon policy, ads and platform updates, directories of agencies, seller tools and influencers, and Amazon seller and ecommerce statistics. It describes no academy, course or in-app AI assistant.⁵⁰
Kuudo: Agent Atlas supplies curated Amazon operating playbooks and rules that your agent retrieves before it acts.⁶⁵

Your data

Where does your account data end up?

Read what each says about your data. Amazon says Seller Assistant keeps seller data within Amazon's infrastructure, and that its plugin connects your Amazon data directly to the AI agent you choose. Jungle Scout's terms grant it a perpetual analytics license on customer data, Helium 10's allow aggregated, anonymous use, ZonGuru's allow de-identified aggregate use, and Nova's say it does not make a figure derived from Amazon data available to third parties. Agent Flow in Private Cloud lands your Ads and Selling Partner data in a data lake in your own cloud.

Amazon Seller Assistant: Amazon's September 23, 2026 article says Seller Assistant "keeps seller data within Amazon's infrastructure and never shares it outside of Amazon", and that the selling partner plugin connects "a seller's Amazon data, including their listing contributions, real-time performance metrics, inventory levels, and sales analytics, directly to their preferred AI agent." It describes no export, history or warehouse sync.⁸
Helium 10: The terms say Helium 10 may use and disclose customer data in aggregated, anonymous form for statistical analysis, service improvement and benchmarking, without identifying the client. They add that data queried through an AI client leaves Helium 10's control. No Helium 10 page describes a warehouse sync.¹⁶
Jungle Scout: The Terms of Use say the customer owns all rights in Customer Data. The customer grants Jungle Scout a license to use it as necessary to provide the Services, and a non-exclusive, perpetual, irrevocable, royalty-free, worldwide license to use the Customer Data for analytics purposes.³²
ZonGuru: The terms say ZonGuru does not sell Customer Data and may aggregate de-identified, non-attributable statistical information from use of the Services to improve them and for industry benchmarking. Third-party AI providers are contractually prohibited from training on customer data.⁴³
Nova: The terms let the customer export data through file exports, data sharing or the MCP connector. Nova may produce statistics from Customer Data for internal purposes, does not make a figure derived from Amazon data available to third parties, whether for one customer or aggregated, without Amazon's written permission or the customer's request, and does not sell Customer Data.⁵¹
Kuudo: Agent Flow in Private Cloud lands your Ads and Selling Partner data in a data lake in your own cloud; your warehouse and BI tools read it downstream.⁶⁷

Where you use it

Which apps can I use it from?

Amazon's selling partner plugin reaches AI clients through what Amazon calls the Amazon Selling Partner Connector (MCP), launching with Amazon Quick and, in beta, Claude, with more integrations to follow. Helium 10, Jungle Scout, ZonGuru and Nova name AI clients that reach their own products. Kuudo connects Claude, ChatGPT, Cursor, Copilot, n8n or any MCP client to Amazon.

Amazon Seller Assistant: Amazon's plugin repository says the skills work "through the Amazon Selling Partner Connector (MCP)", which it registers at https://sellingpartner-ai.amazon.com/mcp. The skills' metadata lists Claude Desktop, Claude Code and Amazon Quick as platforms, and the plugin's description ends "Currently in beta."⁹
Helium 10: The mobile app FAQ says the app runs on Android and iOS and includes Profits, Helium 10 Ads, Alerts, and blogs and podcasts. Account connections and chart downloads are done in the web app. Sub-user accounts can use the mobile app.¹⁷
Jungle Scout: The plans page describes Catalyst as web-based software and the browser extension as available for Chrome and Firefox, pulling product data from Amazon search result pages. Both are included with Starter, Growth Accelerator and Brand Owner. The page mentions no mobile app or AI client.²⁶
ZonGuru: The MCP post gives setup steps for Claude Desktop, Claude.ai on the web, Claude Code and ChatGPT, plus a manual JSON config for any other MCP client through mcp-remote. The connection string is copied from the Integrations page of the Helix web app.⁴²
Nova: The terms define the Services as the Nova web application at app.novadata.io, the Nova MCP Connector for AI assistants, API tokens, data exports and data sharing features. They mention no mobile app and no browser extension.⁵¹
Kuudo: Claude, ChatGPT, Cursor, Copilot, n8n, or any MCP client.⁷¹

Where it runs

Where does it run?

Each of the five is a hosted service, and none publishes an option to run it in your own cloud. Seller Assistant is available on desktop and mobile. ZonGuru says its servers are in the United States, and Nova names servers in France. Kuudo offers Managed MCP, operated by Kuudo, or Private Cloud in your own AWS, GCP, Azure or Cloudflare account.

Amazon Seller Assistant: The support resolution help page says Seller Assistant "is available on desktop and mobile, and it doesn't require any special browser requirements or technical setup", and is available all day, every day. No Amazon page read describes a self-hosted or seller-run option.⁴
Helium 10: The MCP page describes connecting a Helium 10 account to Claude, ChatGPT or a custom agent as one connection the customer does not have to maintain. No Helium 10 page describes a self-hosted option or running in the customer's own cloud account.¹⁹
Jungle Scout: Catalyst is described as web-based software accessed through a Jungle Scout account, with the extension running in the browser. No page mentions a self-hosted or customer-cloud option.²⁶
ZonGuru: ZonGuru states its web and database servers are located in the US and all data is stored there. The article does not describe a self-hosted or customer-cloud option.⁴⁰
Nova: The data processing agreement says the Services are hosted in France by Scaleway in the Paris region, with the application database encrypted at rest and the analytics warehouse on dedicated servers in France. It describes no self-hosted or customer-cloud deployment.⁵²
Kuudo: Choose Managed MCP, operated by Kuudo, or Private Cloud in your own AWS, GCP, Azure, or Cloudflare account. Agent Flow and its data lake run in Private Cloud.⁷¹⁷³

Approval

What happens before anything changes on Amazon?

Amazon says a Seller Assistant workflow can surface recommendations only, or take actions that wait for the seller's review and approval, and that plugin interactions carry human approval on actions and complete audit trails. Helium 10's MCP ad changes wait for you to approve the batch by default, and its help article warns that changed approval settings in Claude or ChatGPT may skip the prompt, Jungle Scout's listing sync waits for a click, ZonGuru evaluates and then confirms, and Nova's MCP reads by default. Kuudo's read tools return data only, and write tools are guarded and may require your explicit approval before a change reaches Amazon.

Amazon Seller Assistant: Amazon's September 23, 2026 article says sellers build Seller Assistant workflows from prebuilt templates or "from scratch", described "in plain language" with guardrails, and that for any workflow "sellers choose whether it just surfaces recommendations or takes actions on their behalf. When it takes actions, sellers stay in control, reviewing and approving them before they're carried out." It says every plugin interaction carries "human approval on actions, and complete audit trails."⁸
Helium 10: The help center says ad changes made through the MCP show the retailer, the account and every proposed action, and run only after the user approves the batch. Campaigns, ad groups and keywords can be paused but not deleted. It warns that changing default approval settings in Claude or ChatGPT may skip the prompt.²⁰
Jungle Scout: A Listing Builder change is sent to Amazon only when the user clicks Sync to Amazon and then Continue. The update is placed in Amazon's queue and shows as Queued To Amazon, Synced To Amazon or Try Syncing Again. The article describes no approval step beyond that click.²⁷
ZonGuru: Through the MCP, edits to Helix records run in two steps, evaluate then confirm, and ZonGuru states nothing publishes to live Amazon listings without the seller. Claude's permission screen separates the 17 read-only tools from the 25 write tools, so writes can be gated.⁴²
Nova: The AI agents page says the Nova MCP reads by default. Listing edits require a workspace owner to turn them on, and each edit is previewed and confirmed before it reaches Amazon. The page says prices and stock levels are not changed.⁵³
Kuudo: Read tools return data only. Write tools are guarded and may require your explicit approval before a change reaches Amazon.⁷⁰

Pricing model

How is it priced?

Amazon's is free to use. Published monthly prices run from $49 to $149 at Jungle Scout and $49 to $249 at ZonGuru by active SKUs, and $129 or $359 at Helium 10, where the AI comes with Diamond. Nova bills per connected Amazon account in eight tiers from $49 to $449 monthly. Kuudo Pro (Private Cloud) is $0 a month plus $0.95 per 1,000 Amazon API calls, priced by Amazon API call, and Kuudo Community (Private Cloud) is free.

Amazon Seller Assistant: The help page FAQ asks "Is the Seller Assistant free or is there a fee to use it?" and answers "It's free to use." The page publishes no usage cap, tier or added fee for Seller Assistant, and quotes no selling plan price.¹
Helium 10: Platinum is $129 a month or $99 a month billed yearly; Diamond is $359 or $279. Enterprise starts at $1,499 a month billed annually. Usage limits scale by plan, Diamond adds a 2% fee on managed ad spend, and add-ons include extra MCP calls from $50 a month.¹⁰
Jungle Scout: With Pay monthly selected, Catalyst Starter is $49, Growth Accelerator $79 and Brand Owner + CI $149 a month. With Pay annually selected they are $348, $588 and $1,548 billed annually. Additional seats are $49 a month each and additional segments $99 a month per 5.²⁶
ZonGuru: Researcher is $49 a month, or $29 a month billed $348 annually. Seller is $79, $159 or $249 monthly for 1-20, 21-100 or 101-1000 active SKUs, or $588, $1,188 or $1,908 billed annually. Enterprise is custom. Prices are in USD.³⁷
Nova: The terms' pricing schedule, applicable from 17 September 2026, bills monthly per connected Amazon account, whatever the number of marketplaces it covers, in eight tiers from $49 to $449. The tier follows the higher of average monthly order items or average monthly sales divided by 50. Their pages disagree on what scales the price: the AI info page says plans scale with Amazon revenue and marketplace count.⁵¹⁵⁵
Kuudo: Kuudo Pro (Private Cloud): $0 a month plus $0.95 per 1,000 Amazon API calls. Kuudo Scale (Private Cloud): $249 a month plus $0.55 per 1,000 Amazon API calls. No percentage of ad spend, and the calculator models a month for a brand owner, an agency or aggregator, and an automation-heavy seller.⁶⁶

Seats and organizations

How many people and accounts?

Amazon's pages disagree on access: one says only the account administrator can grant Seller Assistant, another that all users have access, and no user count is published. Helium 10 runs from one to five users and two to ten Amazon accounts, Jungle Scout includes one seat below its top plan, ZonGuru sells extra users as an add-on, and Nova states no seat count below its Enterprise plan. Kuudo Pro (Private Cloud) allows up to 25 seats across 5 organizations, and Kuudo Scale (Private Cloud) up to 50 across 10.

Amazon Seller Assistant: Their pages disagree on who gets Seller Assistant. The main help page says "Only the administrator of your account can grant permission to use Seller Assistant", by enabling Edit access under User permissions, and warns that secondary users with access can view account data and make account-level or ASIN-level changes. The support resolution help page says "All users have access, though some functions may only be accessible for primary users, depending on your permission settings." No user count is published.¹⁴
Helium 10: The pricing page lists multi-user login of 1 on Platinum and 5 on Diamond, and 2 connected Amazon Seller Central accounts on Platinum and 10 on Diamond. Enterprise lists 10+ users and 15+ seller accounts. Additional users can be bought as an add-on.¹⁰
Jungle Scout: Their pages disagree on Brand Owner: the plan table on the Catalyst plans page and the FAQ on the pricing page say it includes 3 users, while the FAQ on the Catalyst plans page says 10. Starter and Growth Accelerator include 1. Extra seats cost $49 a month or $459 a year. The page sets no limit on connected Amazon accounts.²⁶²⁹
ZonGuru: The Seller plan includes a Seller Central connection to one marketplace, with more through a Connected Regions add-on. Inviting other users requires an Assistant Accounts add-on, with per-tool access. Enterprise lists a sub-account view for each brand and an internal admin dashboard.³⁷
Nova: The pricing page lists unlimited accounts and unlimited team seats on the custom-priced Enterprise & Agency plan. For the Sellers & Brand Owners plan it says additional Seller Central accounts start at $49 monthly each, and it states no number of team seats.⁵⁴
Kuudo: Kuudo Pro (Private Cloud): up to 25 seats across 5 organizations. Kuudo Scale (Private Cloud): up to 50 seats across 10 organizations. Enterprise: unlimited.⁷¹

Free tier

Can I try it free?

Amazon's Seller Assistant is free to use, and Amazon offers every primary account holder a free 12-month Amazon Quick Plus subscription, available through December 31, 2026. Nova gives 14 days with no payment method, ZonGuru a 7-day trial, and Helium 10 and Jungle Scout a 7-day money-back window and no trial. Kuudo Community (Private Cloud) includes 10,000 free Amazon API calls per month, with one instance of each Amazon MCP server in your own cloud.

Amazon Seller Assistant: Amazon's September 23, 2026 article says "every primary account holder globally can sign up for a free 12-month Amazon Quick Plus subscription, available through December 31, 2026", and that primary account holders can designate two additional co-workers to receive a free year of Quick Plus. The article states no price for the selling partner plugin.⁸
Helium 10: The help center says first-time subscribers get a full refund of the first payment when they request cancellation within 7 calendar days. Renewals and later payments are not refundable, and partial periods are not pro-rated. Access continues until the end of the paid period after cancelling.¹⁸
Jungle Scout: The plans page says Jungle Scout does not offer a free trial. New customers on regularly priced Catalyst plans can get their money back within 7 days, requested by email, with special promotions excluded. Subscriptions can be cancelled with no obligation beyond the current billing cycle.²⁶
ZonGuru: ZonGuru offers a 7-day free trial; cancelling inside it avoids a charge. New sign-ups get a full refund if requested within 7 days of the first transaction and a prorated refund up to 30 days. Renewals are not refunded.³⁹
Nova: The terms give new customers a 14-day free trial starting once the first connected account's initial import completes, with no payment method required and no automatic charge at the end. The terms describe no free plan. Fees are non-refundable once a billing period has started, apart from listed exceptions.⁵¹
Kuudo: Kuudo Community (Private Cloud) includes 10,000 free Amazon API calls per month, with one instance of each Amazon MCP server in your own cloud.⁷¹

What we could not verify

Amazon Seller Assistant: Unknown whether Seller Assistant is in the Amazon Seller app: the support resolution help page says "desktop and mobile" but no page read names the Seller app.
Amazon Seller Assistant: Stated as future on older pages: the March 3, 2026 canvas article says "over time, Seller Assistant will execute more of these actions on behalf of sellers, like updating prices or creating restock orders", and the September 17, 2025 article describes inventory monitoring, shipment recommendations and growth plans in the future tense. The September 23, 2026 article describes workflows that "execute routine tasks like restocking and pricing adjustments" as available now.
Amazon Seller Assistant: Availability differs by page and date: the September 17, 2025 About Amazon article says Seller Assistant is available to all sellers in the U.S. store at no additional cost with other countries to follow; the March 3, 2026 article says the canvas experience is available to sellers in the U.S. and U.K. at no additional cost; the September 23, 2026 article says Seller Assistant's capabilities "have rolled out to over 90% of Amazon's selling partners worldwide in their native language" and that the plugin is in beta for sellers in Amazon's U.S. stores; the help page only carries a United States applicability banner; the support resolution help page lists eight languages.
Amazon Seller Assistant: Unknown whether a Professional selling plan is required for Seller Assistant itself: the listing blog ties the AI listing tools to a Professional plan at $39.99 monthly plus selling fees, and the Seller Assistant help page states no plan requirement.
Amazon Seller Assistant: Unknown whether Seller Assistant can change Amazon Ads campaigns: the September 17, 2025 article says it "will" recommend advertising strategies (future tense), and the September 23, 2026 article says it can connect a competitive signal "to an advertising or cross-promotion opportunity" and draft a recommendation; Amazon Ads Agent, Amazon's ad platform, and the Amazon Ads MCP Server that connects outside AI agents to it are Amazon Ads products whose pages do not mention Seller Assistant.
Amazon Seller Assistant: Enhance My Listing (About Amazon, September 19, 2024, modified May 8, 2025) was described as rolling out to select U.S. sellers with recommendations sellers can review, customize or decline; its current availability was not confirmed on a current page and it is not cited in a cell.
Amazon Seller Assistant: The Seller Central help pages show no publication or revision date.
Amazon Seller Assistant: The Seller Central help page "Selling partner plugin for AI assistants" opens only when signed in, so no cell cites it. It says "The plugin works with Amazon Quick and Claude. Access is rolling out to sellers over time", requires an Amazon selling account on a Professional selling plan, and says "Actions require approval by default", "You can limit the assistant to answers only" and "You can disconnect at any time". It says account owners and administrators can authorize the plugin by default, with secondary users managed on the Manage Agents page, that the seller is responsible for all actions the agent takes, and that revoking access "will not reverse prior actions or data access".
Amazon Seller Assistant: Data handling differs by surface: the September 23, 2026 article says Seller Assistant "keeps seller data within Amazon's infrastructure and never shares it outside of Amazon", while the signed-in plugin help page says that once a seller authorizes an agent, "the account and related data is sent to and processed on systems outside of Amazon's control, subject to your AI assistant's terms of service and privacy policy."
Amazon Seller Assistant: Which Amazon operations the plugin's connector exposes is unknown: Amazon's skills repository shows what its skills call, not the connector's full tool list. A web search on 2026-09-26 found no developer-docs.amazon.com page about the plugin.
Helium 10: Which AI model powers Helium Agent, Listing Builder AI generation or the AI image generator is unknown: no Helium 10 page read names a model or provider; the Listing Builder article says only "AI Model Upgrade".
Helium 10: Whether a person must approve before Helium Agent's Listing Builder Skill publishes to Amazon is not stated as an approval rule; the help article lists edit and publish as steps the user takes, and no page read describes an approval setting for listing sync.
Helium 10: Helium Agent limits sit on a different page from the MCP limits cited: the Helium Agent help article says Diamond+ only for four of five agents, a monthly usage limit with no add-ons offered and no figure published, Amazon and Walmart only, and a 14-day attribution window that can differ from Seller Central.
Helium 10: Listing Builder AI limits sit on the Listing Builder help article, not the cited page: Platinum 5 lifetime AI uses, Diamond+ 100 uses per month, one generation counts as one use and each section rewrite as one use.
Helium 10: AI image generation is described only in a Listing Builder help article last updated 2024-09-21: it generates main, Amazon Post, A+ Content and seasonal images from a prompt and style preferences, and the seller downloads the image and uploads it to Amazon; whether this is current was not confirmed on a newer page.
Helium 10: MCP product page client list differs from the help center: the product page names Claude, ChatGPT, GPT, Cursor, Openclaw, Codex and custom agents, while the help article lists Claude (Web and Desktop), ChatGPT and Codex as tested and supported.
Helium 10: The Helium 10 App in ChatGPT help article carries a September 2026 note that it has been succeeded by the MCP; whether the ChatGPT Store app is still offered to new users is unknown.
Helium 10: The Claude Skills page offers four downloadable skill files for Claude that need the Helium 10 connection on a Diamond plan or higher; the download is behind an email form, so the files' contents were not read.
Helium 10: Helium Agent launch timing: the product page says available to Diamond members "starting August 2026" and marks the Ad Diagnostics workflow "Coming Soon"; no page read labels the Agent or MCP as beta.
Jungle Scout: Unknown whether Jungle Scout MCP is read-only: neither the MCP product page nor the help center platform guide states it, and neither publishes call limits, rate limits, a tool list, a connection URL, or a price for the MCP.
Jungle Scout: Unknown whether Catalyst subscribers can use the MCP: the platform guide says access to Cobalt data is required and that the MCP is also sold as a standalone offering powered by Cobalt's data, with eligibility discussed through a customer success manager or a demo request.
Jungle Scout: Conflict on plan gating for AI Assist Chat: the article (last updated 2025-01-30) names Growth Accelerator as limited to knowledge and support questions, which would leave only Brand Owner with business questions among the three plans on the current pricing page; the pricing page does not mention AI Assist.
Jungle Scout: Not included in a cell because it lives on a separate page: the AI Profit Analysis article says the feature uses company and product-level data for a chosen date range to type out a report with recommendations on the top 30 products, needs a connected Seller Central account, and is for Growth Accelerator and Brand Owner users; it is a generated report, not a question box.
Jungle Scout: Not included in the aiListing cell because it lives on a separate page: the publishing article says Sync to Amazon pushes only listings that were imported into Listing Builder, a person clicks Sync to Amazon and Continue, descriptions for products with A+ Content are not supported, and the Handmade category is not supported. No page ties this step to AI Assist specifically.
Jungle Scout: Unknown which model powers AI Assist Chat, AI Profit Analysis and the Listing Analyzer review analysis: only the Listing Builder article names a model provider (Open AI), and it names no model version. The help articles naming these features were last updated between January and February 2025.
Jungle Scout: Unknown which marketplaces the Listing Analyzer review analysis supports: the help article shows the marketplace as an image with no text. The article says the analysis uses the top 50 most recent, most helpful reviews and does not use the word AI except in a link to the AI Assist section.
Jungle Scout: The MCP campaign page (junglescout.com/campaign/jungle-scout-mcp/) adds an FAQ saying Cowork can post a Slack alert or save a report to Drive; the product page cited here words the same point as drafting a brief, updating a tracker, flagging an anomaly.
Jungle Scout: support.junglescout.com returns 403 to curl; the five help articles were read through the public article API at /api/v2/help_center/en-us/articles.json and the cited URLs are the html_url values it returned.
ZonGuru: Unknown which AI models run Helix and the AI Readiness Score: terms section 1.8(d) says AI processing is done by third-party providers that may change, with a current list available on request from support, and no page names them.
ZonGuru: Possible conflict between the Listing Optimizer page, which names ChatGPT-4 (a label OpenAI does not use and that may be dated), and terms section 1.8(d), which says the specific providers may change; the page carries no date.
ZonGuru: Unknown whether the MCP reaches any ZonGuru product other than Helix: the MCP post describes only the Helix connection, and terms section 1.9 and the privacy policy say only "Certain Services, including Helix"; no page names the classic subscription tools (Listing Optimizer, Business Dashboard, Keywords on Fire) as reachable.
ZonGuru: Tension between the MCP post, which says nothing writes to records without the seller's sign-off, and terms section 1.9(c), which deems every action taken through a Connected AI Tool to be the customer's "whether or not you directly reviewed or approved that specific action in advance".
ZonGuru: Not placed in a cell because it lives on the terms page: section 1.8 says AI Outputs may contain errors or fabricated content and the customer must review and approve them; section 1.9 bans using MCP Access to get around rate or usage limits and lets ZonGuru revoke, suspend, monitor and audit MCP Access; no numeric limit is published.
ZonGuru: Unknown whether the 17 read and 25 write tool counts are current: they come from a blog post updated August 25, 2026, not from product documentation, and the Helix app (helix.zonguru.com did not resolve) and the help center publish no MCP tool list.
ZonGuru: Unknown whether Listing Optimizer's AI publishes to Amazon: a help center article titled "What's the difference between Add Listing and Publish on Amazon" exists, but its body is a video with no text, and the Listing Optimizer page does not describe publishing.
ZonGuru: The help center article "How to use AI to generate your listing" (January 25, 2023) is video only, so it confirms nothing in text; help.zonguru.com has no article on Helix, MCP, Claude or the AI Readiness Score.
ZonGuru: The MCP post gives volume credit pricing down to $30 by the 100-credit tier, and the Helix page gives "From $44/ASIN" with savings stated as both 10-20% and 10-25% on the same page; the two savings ranges conflict.
ZonGuru: The MCP post mentions image generation (a carousel image) through the connected assistant, crediting ChatGPT's image model; whether that is a Helix tool or the assistant's own capability is not stated.
Nova: Unknown: which MCP tool performs a listing edit. None of the 21 tools the tool reference names edits a listing.
Nova: In conflict: whether the MCP requires authentication. The MCP server page and the tool reference say "No authentication is required in the current beta", the subprocessors page (https://novadata.io/subprocessors) lists WorkOS, Inc. for "Authentication for the Nova MCP Connector", the terms say the customer connects an AI Assistant "after authorising the connection", and several pages refer to revocable per-account credentials.
Nova: In conflict: MCP call limits. The pricing page (https://novadata.io/pricing) lists "Unlimited MCP Calls" on the plan starting at $49 monthly, while the terms say any "unlimited" usage is subject to fair use and that the trial may carry a maximum number of MCP calls "displayed in the Services"; no page publishes the number of calls.
Nova: Unknown: which model is behind "Nova's Amazon-tuned AI model" on the free title optimizer; no Nova page names it. The subprocessors page lists Anthropic only for AI assistance to the Nova team (support replies and analysing account data to answer customer questions), not as a product feature.
Nova: Unknown: whether the paid product writes listing content. The title optimizer page says the free tool covers amazon.com only with up to 10 free lookups per browser after an email, and says the paid platform covers 23 marketplaces with per-locale title rules, without describing an AI rewrite feature inside the app.
Nova: Unknown: whether the MCP is beta as a whole. The MCP server page says "in the current beta" only in the authentication sentence; the terms define Beta Features generally and class Account Actions and Automated Features as beta unless Nova states otherwise, without labelling the MCP connector itself.
Nova: Unknown: whether the preview-and-confirm step on the import tools can be switched off; the tool reference states it for every import tool and mentions no setting. The terms (section 12.9) separately describe Automated Features that act without a confirmation for each action "where available", and no product page describes one as shipped.
Nova: Unknown: data coverage wording differs by page. The MCP server page lists Vendor Central (1P) and proprietary data as MCP data sources and "several refreshes a day, up to every 30 minutes", while the AI agents page says "Refreshed hourly"; the aiReaches cell uses the AI agents page wording only.

Frequently asked questions

Questions sellers ask about AI for Amazon.

What Amazon's own AI does, what a vendor's AI reaches, whether ChatGPT or Claude can do the work, and where Kuudo fits.

What is the best AI for Amazon sellers: Amazon Seller Assistant, Helium 10, Jungle Scout, ZonGuru, or Nova?

It depends on where you want the AI to live. Amazon's Seller Assistant is free and built into Seller Central, reads your account data, and can act with your permission, and its selling partner plugin, in beta for sellers in Amazon's U.S. stores, brings it into Amazon Quick and Claude. Helium Agent sits inside the Helium 10 dashboard and answers from your Helium 10 data. Jungle Scout, ZonGuru and Nova connect your own AI client to their products through an MCP. Kuudo connects the AI you already use to Amazon's own operations, across ads, seller and vendor work.

What AI tools does Amazon give sellers?

Several, in different places. Seller Assistant, in Seller Central, answers account questions and, in Amazon's words, can take actions on your behalf with your permission. Its workflows start from prebuilt templates or a plain-language request, and its selling partner plugin, in beta for sellers in Amazon's U.S. stores, brings it into Amazon Quick and Claude. Generative listing tools draft titles, bullets, descriptions and A+ Content that you review, edit and approve. Amazon Ads Agent, Amazon's renamed ad platform, has a conversational experience in closed beta that builds campaigns and generates Amazon Marketing Cloud SQL, and a Creative Studio tool in beta produces video and display ads at no additional cost.

Can I use ChatGPT or Claude for my Amazon business?

Yes, and the question is what it can reach. Used by hand, it works from what you paste or upload. Connected through an MCP, it reaches whatever that MCP points at. Helium 10's, Jungle Scout's, ZonGuru's and Nova's each point at the vendor's own product. Amazon's selling partner plugin, in beta for sellers in Amazon's U.S. stores, brings Seller Assistant and your selling account's data into Claude and Amazon Quick through what Amazon calls the Amazon Selling Partner Connector (MCP). Kuudo's MCP servers point at Amazon's own operations for Ads, Selling Partner and Vendor Central.

Can AI take actions on my Amazon account, and who approves them?

Some can, and the approval step differs. Amazon says Seller Assistant acts with your permission, and that its workflows and its plugin wait for a person's approval before an action is carried out. Helium 10's MCP changes ads after you approve each batch by default, and its help article warns that changed approval settings in Claude or ChatGPT may skip the prompt. ZonGuru's writes change records in its Helix product in two steps, not live listings, and Nova's pages disagree on listings: its tool reference says campaigns, prices and listings stay as set, and its AI agents page describes listing edits a workspace owner turns on. With Kuudo, write tools are guarded by your workspace policy, may require approval, and every call is recorded with its approval state.

Which AI writes Amazon listings, and does it publish them?

Each tool on this page writes listing text of some kind. Amazon's generative tools draft listings and A+ Content that you approve before submitting. Helium 10's Listing Builder skill can publish to Amazon or export. Jungle Scout's AI Assist writes copy a person accepts or discards, ZonGuru's Helix output is copied or exported as a CSV, and Nova's free title rewriter returns text. Kuudo's Listing Optimizer reads the live catalog record, rewrites against Amazon's limits, previews the change and writes it on your approval.

What does AI for Amazon sellers cost?

Amazon's Seller Assistant is free to use, and Amazon offers primary account holders a free 12-month Amazon Quick Plus subscription through December 31, 2026. Published monthly prices run from $49 to $149 at Jungle Scout and $49 to $249 at ZonGuru, and Helium 10 is $129 or $359, with its AI included on Diamond. Nova bills per connected Amazon account, from $49 to $449 monthly. Some cap usage: Helium 10 includes 1,000 MCP calls a month, and Jungle Scout allows 50 or 300 AI clicks by plan. Kuudo Private Cloud is priced by Amazon API call, and Kuudo Community (Private Cloud) is free.

How does Kuudo compare to Amazon's Seller Assistant?

Seller Assistant is Amazon's AI and free to use. It works inside Seller Central, and its selling partner plugin, in beta for sellers in Amazon's U.S. stores, brings it into Amazon Quick and Claude, with actions waiting for your approval by default. Kuudo connects the AI client you already use to Amazon's operations across Ads, Selling Partner and Vendor Central. Choose Managed MCP or Private Cloud, use Skills you can read and write, and set your policy for writes. Kuudo is in private beta. No Amazon page read describes Seller Assistant working in Vendor Central.

The bottom line

Put the AI you already use to work on Amazon.

Amazon's assistant works on your selling account, in Seller Central or through its plugin, and a vendor's AI works inside its product. Kuudo connects ChatGPT, Claude or the client you prefer to Amazon's own operations through Managed MCP or Private Cloud, using Skills or ones you write, with writes subject to the policy you set. Kuudo Pro (Private Cloud) starts at $0 a month.
