What is CopilotKit?

CopilotKit is an open-source framework that helps developers add AI copilots to their applications without building AI systems from scratch. It connects your app's components to a central copilot engine, managing the communication between front-end and back-end so you can focus on features rather than infrastructure. The framework includes pre-built UI components, state management tools, and integrations with LangChain and LangGraph. This means you can create chatbots, AI agents, and other AI-powered experiences more quickly. It also supports human-in-the-loop interactions, letting users override or correct AI decisions when needed. CopilotKit is designed for developers who want to add AI capabilities to existing applications without significant complexity. Being open-source, you can self-host it or use Copilot Cloud for managed hosting and scaling.
