Definition
CopilotKit is an open-source React framework for embedding AI copilots — chat assistants, in-app actions, and autonomous agents — directly into web applications with pre-built UI components and hooks.
Overview
CopilotKit is designed to shortcut the significant frontend and backend plumbing normally required to add an AI assistant to an existing application. It provides React components for chat sidebars, popups, and inline text assistance, along with hooks that let a copilot read application state and trigger actions inside the app — for example, filling out a form or navigating to a page on a user's behalf, rather than only answering questions in a chat window. Under the hood, CopilotKit connects to LLM providers such as OpenAI and can be paired with agent frameworks and orchestration tools to give the copilot more complex, multi-step AI agent capabilities, similar in spirit to how the Vercel AI SDK handles model calling and streaming, but with a stronger focus on pre-built, application-aware copilot UI and in-app actions rather than just the model-calling layer. Because it targets React and Next.js applications specifically, CopilotKit is commonly used by teams that want to add contextual, action-capable agentic AI assistants to SaaS products without building the chat UI, state management, and action-execution plumbing from scratch.
