Beautiful Chat
A polished starter layout: the built-in CopilotChat dropped onto a two-pane canvas, with suggestions pre-wired and the disclaimer slot customized away. Everything is theme-aware and responsive.
In-process runner
The CopilotKit runtime runs inside the Next.js route handler — there is no separate agent server.
TanStack AI
Backend tools defined with toolDefinition() stream through the agent factory.
Tailwind theme
Colors come from the global CopilotKit CSS variables; flip the page to dark mode and the chat follows.
Drop-in primitives
<CopilotChat /> ships with messages, input, suggestions, and disclaimer slots out of the box.
