assistant-ui is a TypeScript and React library for building AI chat interfaces. The documentation describes its components, runtimes and primitives for React, Vue, React Native and the terminal, and the README shows a new project started with a CLI or the packages installed from npm.
The README lists integrations for backends such as the Vercel AI SDK, LangGraph and LangChain.
Worth knowing
Hosted persistence is a separate service. The pricing page describes assistant-cloud as an optional backend for threads, history and auth.
