Multi-agent switching
Connect LangGraph, Agno, or any AG-UI backend. Switch agents per conversation — no UI changes needed.
AG-UI protocol native
Built on CopilotKit, the 1st-party AG-UI client. Streaming, interrupts, tool renders — all standard.
Human-in-the-loop
Approval interrupts let agents pause for your sign-off before taking sensitive actions.
Tool-call visualization
See what your agents are doing as they work — structured tool renders, not raw JSON.
