what we build
The panel and the connections behind it
We build the MCP server, the selection interface and customer sign-in. The app only sees the data you allow.
the public directory
Prepare for the ChatGPT apps directory
We prepare the listing, visual assets, test access and scenarios for reviewers. OpenAI reviews the submission; an approved app can then be published in the directory.

Frequently asked questions
What is a ChatGPT app, and how is it different from a chatbot?
A ChatGPT app runs inside ChatGPT and can show its own interactive panel. A chatbot on your website talks to visitors there. For that option, see our AI chatbot service.
How do you use OpenAI Apps SDK and an MCP server?
A ChatGPT app is built on an MCP server. The server describes actions and connects your systems to the assistant. OpenAI Apps SDK lets us add an interface in the conversation. See MCP server development for the server side.
Have you connected a service to ChatGPT before?
Yes - we developed an MCP server that lets users access an image search and generation platform from ChatGPT, Claude and Cursor. It uses OAuth 2.1 sign-in and a separate quota for each client. We measured results and tuned the responses for each assistant.
Can customers sign in with their existing account?
Yes, where your system supports the connection. We build OAuth 2.1 sign-in and check permissions on every request.
Who can see personal data, and where is it stored?
We agree what data the app needs, what is sent to ChatGPT and what records the server keeps. The server enforces access rules. Secret keys stay on the server; personal orders and customer-specific prices require sign-in.
Will the app be listed in the ChatGPT app store?
The public directory is often searched for as the ChatGPT app store. We prepare the listing, visual assets, test access and review scenarios. OpenAI reviews the submission and decides whether to approve it. Publication and review timing are controlled by OpenAI.
Can customers complete a booking or purchase?
We build room or product selection and the connection to your system. Confirmation, payment and checkout steps depend on the project and OpenAI’s current rules. We check these before agreeing the scope.
What does ChatGPT app development cost?
Pricing is on request. The actions, panel, sign-in and system integrations determine the scope. We list hosting, external APIs, any AI model usage and ongoing support separately.
How long does it take to build a ChatGPT app?
We give a timeline after checking your systems and choosing the first task. We build a working version, then test it with your team. Preparing a public submission is a separate step from development.
shall we start?
What should customers do in your ChatGPT app?
Show us your catalogue, schedule or service. We will agree on the first task and the connections it needs.
