I made a chat UI kit just for your use case.
When I started researching chat, it became clear that there are five common use cases:
- Social messaging
- Email replacement for teams
- Livestream broadcasts
- Gaming
- Sales and support
Each example in the Chat UI Kit is designed for the specific demands of each use case. It is my hope that everyone who uses this chat ui kit finds these examples to be flexible and adaptable to their own application.
