Overview
How might we design message pinning so people can trust and act on AI output?
When to use
- Ideal for long conversations, research sessions, and collaborative chats where users need quick access to key information.
When to skip
- Ephemeral chats that are deleted after the session.
- Products that already use a dedicated doc or artifact for the same content.
- Threads where everything is equally important (pins lose meaning).
Rules
Pins with no unpin or pin limit.
Pinned content that does not jump to the original turn.
Pins invisible on mobile.
Auto-pinning every AI answer until the pin list is useless.
