The AI chat app that remembers what you figured out.

Your best thinking with AI ends up in conversations you'll never find again. Shin keeps the thread — workspaces, auto-summaries, and connected chats.

No spam. One email when we launch.

What makes it different

Your conversations,
as a thinking archive.

ChatGPT and Claude treat chats as disposable. Shin treats them as something worth keeping — scoped, summarized, searchable.

game-dev 12 chats
writing 9 chats
research 6 chats

Workspaces

Scoped context. Your game-dev chats don't pollute your writing chats.

Summary

Rollback netcode wins over lockstep for this game's pacing. Input delay pinned to 2 frames. Authoritative saves sync via cloud.

Auto-summaries

Every conversation becomes a 2–3 sentence 'here's what we figured out.'

  • Rollback, not lockstep
  • 2-frame input delay
  • Cloud-authoritative saves

Extracted decisions

Key conclusions pulled out automatically. Skimmable at a glance.
