Slots
What is this?
Slots let you customize CopilotKit's pre-built chat components without building everything from scratch. Override specific parts of the UI — message bubbles, input areas, headers — while keeping the rest of the default behavior.
When should I use this?
Use slots when you want to:
- Customize specific parts of the chat UI (e.g. message rendering, input area)
- Match your app's design system without building a fully custom chat
- Add custom elements like typing indicators, avatars, or action buttons
