What is the ChatGPT app directory?

A directory of third-party apps that run inside ChatGPT conversations, found from the tools menu and at chatgpt.com/apps. OpenAI began accepting developer submissions on December 17, 2025, and said approved apps would roll out to users starting in early 2026. Apps are built with the Apps SDK, which runs on the Model Context Protocol.

Can a ChatGPT app sell subscriptions?

Not at launch. VentureBeat's December 18, 2025 coverage reported that ChatGPT apps could link out to external websites to complete purchases for physical goods only, and that selling digital goods, subscriptions or in-app services was not yet allowed, though OpenAI said it was exploring more options. Check OpenAI's current app submission guidelines, because these rules may have changed.

Is a ChatGPT app worth building for a consumer mobile app?

It is worth it when your app does a job that fits a conversation, like searching listings, planning a trip or generating something, and when a lighter version inside ChatGPT can lead people to the full app. It is a poor fit if your value depends on things a chat cannot provide, like background tracking, notifications or a camera-first experience.

How do I track installs that come from my ChatGPT app?

Put a tracked link on every handoff from the ChatGPT app to your mobile app or website. A unique link per surface lets your attribution SDK credit the install to the ChatGPT app instead of logging it as organic. Without one, installs that start in ChatGPT look like organic store search.

The short version

On December 17, 2025, OpenAI started accepting third-party submissions for an app directory inside ChatGPT, built on its Apps SDK, which runs on the Model Context Protocol (VentureBeat, December 18, 2025). The directory lives in the tools menu and at chatgpt.com/apps, approved apps were set to roll out starting in early 2026, and OpenAI cited 800 million+ ChatGPT users.

For a mobile app developer the question is simple: is a small version of your app inside ChatGPT a useful way to reach new users, or a distraction? This post gives you a way to decide, plus the commerce rules as they stood at launch and how to make the handoff to your real app measurable.

What a ChatGPT app is, in one paragraph

A ChatGPT app is an MCP server plus an optional interface that ChatGPT renders inside the conversation. The user asks for something ("find me a two-bedroom near the park under $3,000"), ChatGPT calls your app's tools, and your results appear in the chat. Launch partners at the time included Booking.com, Canva, Coursera, Expedia, Figma, Spotify and Zillow. Because it is built on MCP, the same server can in principle work in other assistants that support the protocol.

The rules at launch

From VentureBeat's December 2025 coverage:

Submissions go through the OpenAI Developer Platform with MCP connection details, testing instructions, directory metadata and country availability. Developers can test privately first in ChatGPT's developer mode.
Apps must be suitable for general audiences, including teens, include a clear privacy policy and support contact, and avoid advertising and deceptive behavior.
Only one version of an app can be under review at a time.
Commerce: apps could link out to complete purchases of physical goods only. Selling digital goods, subscriptions or in-app services was not yet allowed.

That last rule is the important one for subscription apps. If it still holds when you read this, a ChatGPT app is a top-of-funnel channel for you, not a place to earn directly. Check OpenAI's current app submission guidelines before you plan around it; the rules were described as an early phase.

Who it makes sense for

Your app's core job	Fit for a ChatGPT app	Why
Search or lookup (listings, recipes, flights, products)	Strong	Natural as a tool call; results render well in chat
Generation (designs, plans, workouts, itineraries)	Strong	The user asks; your app makes the thing
Learning and practice (languages, quizzes)	Medium	A taste works in chat; the habit loop needs the app
Tracking (habits, fitness, finance syncing)	Weak	Value comes from background data and notifications
Camera, audio or location first	Weak	The chat cannot reach the sensor
Social or multiplayer	Weak	The network lives in the app

The pattern: if your app answers requests, a ChatGPT app can show it off. If your app's value builds over days of use, the ChatGPT version is a demo at best.

Turn it into installs you can measure

A ChatGPT app that never sends anyone to your real product is a free tool for OpenAI's users. To make it a growth channel:

Give the chat version a clear ceiling. Let it do one useful thing well, and make the next step ("save this plan," "get reminders," "sync with your bank") happen in the mobile app.
Put a tracked link on every handoff. Use a unique link for the ChatGPT surface so your attribution SDK credits those installs to it. Without one, they land as organic store search, the same blind spot covered in tracking installs that start in ChatGPT.
Name the job the way people ask for it. Directory search and model tool selection both match on language. The same one-sentence job description that helps you get recommended by AI assistants belongs in your directory metadata.
Ship the same server to more than one client. An MCP server that works in ChatGPT can serve other MCP clients too, and on iOS, App Intents cover Siri. One set of well-described actions, several assistants.

The cost side

A minimal ChatGPT app is an MCP server with a few tools over APIs you already have, the most common pattern in the ecosystem: Zuplo's early-2026 survey found 58% of MCP builders were wrapping existing APIs (Nordic APIs, June 4, 2026). Budget for the review cycle, a privacy policy that covers the new data flow, and ongoing maintenance as the SDK changes. If you used a coding agent to build your mobile app, it can build the MCP layer too.

When to skip it

Your app is in the weak-fit rows above.
You have not yet found a channel that reliably brings installs. A ChatGPT app is another surface to maintain, and it will not fix a listing that does not convert.
You need revenue from the surface itself and the commerce rules have not changed.

For most early-stage mobile apps, the higher-return move is still getting creators to show the app to people who already want it, and making sure those videos carry tracked links that assistants can cite. Add the ChatGPT app once you know which job your users value most.

Need installs now, while you decide? Create a pay-per-install campaign on IdeaEquity and let creators in your niche show what your app does.
