Assistant-UI is an open-source React component library designed to help developers quickly build high-quality AI chat interfaces similar to ChatGPT inside their own products.
The core library is open-source and free to use. The project also mentions optional cloud services; please refer to the official pricing for details.
It supports integrating major models like OpenAI, Anthropic Claude, Google Gemini, and is compatible with Vercel AI SDK, LangChain, and adapters to connect to custom APIs.
You can bootstrap a project quickly via the CLI, for example running `npx assistant-ui init` or `npx assistant-ui@latest create my-app` to create an app skeleton.
Assistant-UI is designed specifically for the React ecosystem; its core advantage lies in deep integration with React and TypeScript, so it is mainly suitable for React projects.
As a front-end UI library, it primarily handles UI rendering and interaction logic. Details of AI calls, data processing, and storage security depend on the back-end services and APIs configured by the developer.
