## Best for
Putting an existing agent in front of users with rich, interactive UI rather than a plain chat box.

## About CopilotKit
CopilotKit is an SDK for full-stack agentic applications that sits between your agents and your users, providing generative UI, shared state and human-in-the-loop workflows for React, Angular, Vue and React Native and inside Slack and Microsoft Teams. Its makers created the AG-UI protocol, which the README says Google, LangChain, AWS, Microsoft, Mastra and PydanticAI have adopted. An optional CopilotKit Intelligence layer adds persistent threads and user memories in production.
