<CopilotChat> is the base prebuilt chat surface. Drop it in wherever you
want the chat to render and size it to fit your layout. <CopilotSidebar>
and <CopilotPopup> are both thin wrappers over the same primitives; if you
need a dedicated chat page or an inline pane alongside other content, this
is the component you want.
Use <CopilotChat> when you want:
- A full-bleed chat that fills its container
- An inline chat pane as part of a larger page
- A dedicated
/chatroute - Maximum layout freedom (no docked chrome or launcher)
For a collapsible docked chat, use CopilotSidebar. For a floating bubble that overlays content, use CopilotPopup.
Wrap your app in <CopilotKit> once (the provider wires the runtime, session,
and agent registry) and render <CopilotChat> inside the layout of your
choosing:
A self-contained component that renders the chat and wires in starter suggestions:
<CopilotChat> is the root primitive. <CopilotSidebar> and <CopilotPopup>
accept the same slots and labels, plus a few wrapper-specific props.
