## What it is
CopilotKit is an open-source frontend SDK for building agent-native applications with generative UI, shared state, chat interfaces, and human-in-the-loop workflows. It connects any AG-UI-compatible agent backend (LangChain, Claude Agent SDK, PydanticAI, etc.) to React, Angular, Vue, React Native, Slack, and Microsoft Teams surfaces.

## Use cases
- add an ai chat copilot to my react app
- render agent tool calls as react components in the ui
- build a chatbot ui connected to my langchain agent
- let ai agents share state with my frontend
- add human-in-the-loop approval to agent workflows
- expose my agent in slack or microsoft teams
- build generative ui with claude agent sdk

## When to choose
- you want production-ready chat or generative UI components wired to your own agents
- you need one agent to reach web, mobile, and messaging surfaces
- you want frontend tools, shared state, and human-in-the-loop out of the box
- you use an AG-UI-compatible agent framework like LangChain, Claude SDK, or PydanticAI

## When to avoid
- you only need a raw LLM API client without UI components
- you are not using React-family or supported frontend frameworks
- you want a fully self-contained agent runtime with no external service dependency
- you need a non-JavaScript frontend stack
