Assistant UI is an open-source TypeScript/React library that provides production-ready UI components and state management for building AI chat interfaces. It delivers a drop-in, ChatGPT-style UI with theming, high-performance rendering, and support for streaming, interruptions, and multi-turn conversations across Vercel AI SDK, LangChain, LangGraph, or any LLM provider. Conversations and streaming output are powered by Assistant UI Cloud, which renders the chat interface and stores threads so sessions persist across refreshes.
