How to get your product listed in ChatGPT and Claude (2026)

You want people to type "book me a table for Friday" or "find last month's invoice" into an AI assistant and have your product do it. That means getting listed. Both ChatGPT and Claude run a directory, and both review what you submit.

This post covers why it's worth the effort, what each directory checks (side by side), what the first big brands built, and the mistakes that send submissions back. We've read both directories' public docs as of 17 October 2026. They change often, so follow the links before you submit.

Why bother: the audience

The numbers are hard to ignore:

And people arriving from AI are worth having. Adobe found that in March 2026, AI-referred visitors to US retail sites converted 42% better than other traffic, with 37% more revenue per visit (TechCrunch).

A listing doesn't guarantee any of that traffic. But without one, your product can't be used inside the conversation at all.

What you're actually submitting

Both directories are built on MCP, the Model Context Protocol. Your app is a small server that sits in front of your product and lists a handful of tools ("search products", "create a booking"). When someone asks the assistant for something, it calls a tool and your server does the work.

The directories review that server and its listing, not your website. OpenAI's docs now call submissions plugins: a package that can hold an MCP server, skills, or both. Claude calls them connectors.

Who went first

The first wave was big consumer brands and the tools businesses already live in.

Look at what they exposed. Spotify recommends music and podcasts by mood (Spotify). Zillow shows listings on a map. Stripe gives Claude access to customer and payment data. Notion and Asana read and update work. None of them put their whole product in the chat. Each picked a few jobs people already ask for.

We look at the big brands in more detail in who's already inside ChatGPT, Claude and Copilot.

ChatGPT in more detail

OpenAI's reviewers look for:

• A clear purpose that ChatGPT can't already cover on its own, with no impersonation or implied OpenAI endorsement.
• Quality. Predictable results, sensible error handling, and no trial or demo builds.
• Honest tools. Unique, action-oriented names and accurate descriptions, one operation per tool.
• Minimal data. Only the inputs you need, responses limited to what's relevant, never the full chat history.
• Privacy. A published privacy policy, and no collecting payment card data, health records, government IDs or passwords.
• Works everywhere. Reliable on desktop and mobile.
• A real contact. Accurate support details for your verified organization.

Claude in more detail

Anthropic organises its checklist around the most common rejections:

• No catch-all tools. A tool that both reads and writes is rejected. Split reads from writes, ideally writes into create, update and delete.
• Narrow, accurate descriptions. Say what the tool does and when to use it.
• No instructions aimed at Claude. Descriptions that tell Claude how to behave count as prompt injection.
• Useful errors. A bare "Internal Server Error" fails.
• Reasonable responses. Return what the task needs, not a database dump.
• Your own API. Call your first-party API, or one you're allowed to proxy.
• Names of 64 characters or fewer.

The listing itself has hard limits: a name of up to 100 characters, a one-liner of up to 200 and a description of up to 2,000, in 1 to 5 categories. Your listing's URL slug is permanent once published.

The mistakes that get apps bounced

Put the two checklists together and the same problems keep coming up. None of them is hard. All of them are easy to miss the first time:

1. Missing or wrong annotations. Every tool needs them, and ChatGPT wants all three hints set explicitly, even when the answer is false.
2. Vague tool names and descriptions. "process", "handle_request", "Makes a request to the API". Research on 856 tools found 97.1% of descriptions had at least one problem (study).
3. An empty test account. Reviewers need realistic data to try your tools. A fresh account with nothing in it fails the test.
4. Sign-in that only works for you. OAuth has to work for a stranger, from ChatGPT's or Claude's side, on the first try.
5. One tool that does everything. Claude rejects it outright, and ChatGPT asks for one operation per tool.
6. Errors that say nothing. "Something went wrong" tells the agent nothing it can fix.
7. No published privacy policy.
8. A server that's slow to wake up. In our experience, reviewers and users see timeouts.

After you're listed

Approval is the start. ChatGPT rescans hosted servers daily and publishes eligible tool changes after automated checks. So a rename on your server can change what people see in ChatGPT the next day. On Claude, tool changes go live when you deploy them, but changing the tool names on your listing takes a reviewed listing edit. Our guide to keeping your listings healthy covers what to watch.

What this means for you

• The audience is there. Hundreds of millions of people use these assistants every week.
• Big brands started with a few focused jobs. You can do the same with a much smaller team.
• Both directories check similar things: honest tools, working sign-in, a real test account, a privacy policy and a server that stays up.
• Nobody can promise a listing. Each directory decides for itself.

Where Transica fits

Transica builds the app from your product, checks it against both directories' rules before you submit, and hosts it on your own domain behind the sign-in you already have. We can't speed up a directory's review, and a listing is never guaranteed. What we can do is make sure you don't get bounced for something a checklist would have caught.
