What is it?

Open Intelligent UI is a chat application built with CopilotKit and the AG-UI protocol. Instead of replying only with text, the agent picks the most useful presentation for a request: a direct text answer, a native component for structured data such as tables, or a custom interactive interface generated as sandboxed HTML, CSS and JavaScript.

The project targets questions that benefit from interaction, such as explaining a mechanism with a 3D model, comparing options in a table that becomes a chart, or building a small tool like a bill splitter whose calculations update as inputs change. Generated interfaces run in an isolated iframe, and user-clicked follow-ups can send selected values back to the agent to start another turn.

The repository is a monorepo with a Next.js and CopilotKit frontend, a Python Deep Agent served by FastAPI, and an optional standalone MCP server. Visualization routing sends tables to A2UI and charts, diagrams and maps to Open Generative UI. Users can supply their own OpenAI and routing API keys in the chat header.
