Built-in Agent (TanStack AI)Build Generative UIYour ComponentsDisplay Components

Display Components

Register React components that your agent can render in the chat.

What is this?#

Display-only generative UI lets you register React components as tools your agent can invoke. When the agent calls the tool, CopilotKit renders your component directly in the chat with the tool's arguments as props; no handler logic or user interaction required.

Info

Free course: See this pattern built end-to-end in Build Interactive Agents with Generative UI — a free DeepLearning.AI short course taught by CopilotKit's CEO covering the full Generative UI spectrum (Controlled, Declarative, and Open-Ended).


useComponent({
name: "showChart",
description: "Populate data and show the user a chart",
parameters: ChartProps,
render: Chart
});

When should I use this?#

Use display-only generative UI when you want to:

  • Display rich UI (cards, charts, tables) inline in the chat
  • Show structured data from agent responses
  • Render previews, status indicators, or visual feedback
  • Let the agent present information beyond plain text
