Build Apps in ChatGPT with the OpenAI Apps SDK
Leverage the OpenAI Apps SDK, introduced at DevDay 2025, to create interactive, AI-powered apps inside ChatGPT. 10Clouds helps you design, develop, and launch custom ChatGPT apps powered by the Model Context Protocol (MCP).
What Is the OpenAI Apps SDK?
The OpenAI Apps SDK is a new developer framework that allows you to build and test apps directly inside ChatGPT. Announced at OpenAI DevDay 2025, the SDK lets developers create interactive, context-aware apps using the Model Context Protocol (MCP) — an open standard that connects models with external tools and data.

How do you build an app in ChatGPT?
You can build a ChatGPT app using the Apps SDK by defining its logic, UI, and connections to external APIs, then testing it within ChatGPT’s preview environment.
What is the Model Context Protocol (MCP)?
The Model Context Protocol (MCP) is an open standard that connects AI models to external data and tools securely, allowing context-aware, dynamic apps inside ChatGPT.
When will OpenAI start accepting app submissions?
OpenAI plans to begin accepting app submissions for publication later in 2025.

From AIConsole to Apps Inside ChatGPT
AIConsole
Before the OpenAI Apps SDK, we created AIConsole, an open framework for building, testing, and managing AI agents. It connects models, data, and tools into transparent, controllable workflows — from automation to real-time assistance. This hands-on experience now powers how we design context-aware apps inside ChatGPT, using the same principles of flexibility, safety, and human oversight.

How the OpenAI Apps SDK Works
The OpenAI Apps SDK uses the Model Context Protocol (MCP) to connect ChatGPT with external tools and APIs. It lets developers build interactive app UIs inside ChatGPT that react to user input and context in real time.
When a user interacts with your ChatGPT app, the model sends structured requests to your MCP server, which executes logic, calls APIs, and returns results as context-aware responses rendered directly in the chat.
This setup enables secure data exchange and smooth, interactive experiences, all running inside ChatGPT.
