</CopilotSidebar>

A chatbot sidebar component for the CopilotKit framework. Highly customizable through various props and custom CSS.

See CopilotPopup for a popup version of this component.

To make the sidebar push your content to the side, wrap your content in the sidebar component. If you want the sidebar to overlay your content, place the sidebar component outside of your content.

​
Custom CSS

You can customize the colors of the chat window by overriding the CSS variables defined in the default styles.

For example, to set the primary color to purple:

<div style={{ "--copilot-kit-primary-color": "#7D5BA6" }}>
  <CopilotSidebar />
</div>

To further customize the chat window, you can override the CSS classes defined here.

For example:

.copilotKitButton {
  border-radius: 0;
}
