Copilotkit

CopilotKit is an open-source framework for embedding AI copilots directly into web applications so they behave like native product features rather than external chat widgets. It provides the infrastructure to connect large language models or agents to your app’s live data, business logic, and user interface, enabling context-aware assistance, automation, and interactive workflows. The primary purpose of CopilotKit is to let product teams ship in-app AI experiences quickly while retaining full control over UX, security, and data flow.

At its core, CopilotKit offers a React-based integration layer that lets you expose application state, domain objects, and UI components to the copilot in a structured way. It supports real-time context streaming, so the AI always operates on up-to-date information, and includes tools for safe UI control, allowing the copilot to trigger actions, modify views, or guide users step-by-step. Developers can plug in different LLM providers, define custom tools and actions, and configure granular permissions over what the AI can see and do. Because it is open source and framework-centric, teams can self-host, extend, and audit the behavior of their copilots rather than relying on opaque third-party overlays.
