The interaction layer
between agent and app.

Your agent handles reasoning and execution. CopilotKit makes its work available as an interactive product experience.

AGENT → APPLICATION

Show the work as it happens.

Bring messages, tool activity, and state updates into the interface as events. Give people visibility into what the agent is doing.

APPLICATION → AGENT

Keep the agent in context.

Share the state of the application and connect the tools the agent needs to act inside it.

PEOPLE ↔ AGENT

Make room for human judgment.

Collect input, approvals, and corrections as part of the interaction. Let people guide the next step.

Open protocols.
A stack that stays yours.

AG-UI connects agents to users. MCP connects them to tools and context. A2A supports agent-to-agent communication. Use each where it belongs.
