How to add an agent with chat and generative UI to your existing app with Copilot Kit

Let your coding agent run Copilot Kit's onboarding command, which inspects your project and guides the integration.

Short answer: Open your coding agent at the root of your project; then give it the README prompt that runs npx --yes copilotkit@latest onboard start; follow the onboarding instructions it prints. All steps.

Who it is forA developer with a working React or Next.js app who wants an in-app agent.

The problemWiring chat, tool calls and UI updates between an agent and a frontend by hand takes days.

The outcomeCopilot Kit integrated in your app with a chat UI that streams messages and renders tool calls.

What you need first

  • Node.js and npx
  • An existing React, Angular, Vue or React Native app, or a new one scaffolded by the CLI
  • An agent backend or LLM provider for the agent

Steps

  1. Open your coding agent at the root of your project
  2. Give it the README prompt that runs npx --yes copilotkit@latest onboard start
  3. Follow the onboarding instructions it prints
  4. Test the chat UI and one backend tool that renders UI in the client

Prompt for your agent

Help me get started with CopilotKit/CopilotKit. From the root of my project run npx --yes copilotkit@latest onboard start, follow its instructions for my <framework> app, and add one tool that renders UI.

Caveat.
