Get the UX of ChatGPT in your own mobile app
Beautiful, production-ready AI chat for React Native. Powered by the same runtime as assistant-ui, with full Expo support and cross-platform code sharing.
Why assistant-ui for React Native?
Everything you need to build a world-class AI chat experience on mobile — without starting from scratch.
First-class Expo support. Use Expo Router, EAS Build, and the full Expo ecosystem out of the box.
Write once, run on every platform. Share UI components and business logic across iOS, Android, and web.
Powered by the same engine and runtime system behind assistant-ui.com, refined over two years of production use.
Works with Vercel AI SDK, LangGraph, and other popular frameworks. Plug in your existing backend with zero changes.
Already using assistant-ui on the web? Reuse the same runtime, tools, and adapters in your React Native app.
Composable, unstyled primitives — Thread, Composer, Message, and more — designed for native from the ground up.
Already using assistant-ui?
Your existing runtime setup, tool definitions, and model adapters work with the React Native package. Share the same code between your web and mobile apps — only the UI layer changes.
