Display Components

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.


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


export const ChartProps = z.object({
  title: z.string(),
  data: z.array(z.object({ label: z.string(), value: z.number() })),
});

export function Chart({ title, data }: z.infer<typeof ChartProps>) {
  return (
    <div>
      <h3>{title}</h3>
      <ResponsiveContainer width="100%" height={300}>
        <BarChart data={data}>
          <XAxis dataKey="label" /><YAxis /><Tooltip />
          <Bar dataKey="value" fill="#6366f1" />
        </BarChart>
      </ResponsiveContainer>
    </div>
  );
}

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
