# Build React agent chat interfaces with assistant-ui

Use assistant-ui to build production React chat interfaces with reusable threads, runtimes, message components, and model/provider adapters.

## Prerequisites

React application, @assistant-ui/react, runtime adapter such as @assistant-ui/react-ai-sdk, backend model or agent endpoint

## Installation

Use the upstream install or setup path that matches your environment:
- npx assistant-ui@latest create # new project
- npx assistant-ui@latest init # add to existing project
- npm install @assistant-ui/react @assistant-ui/react-ai-sdk

Basic usage or getting-started notes:
- The fastest path is the CLI, which scaffolds a Next.js app or adds the styled components to an existing project:
- bash
- Or install the packages directly:
