Conversation History
Every Claude session is preserved. Come back hours or days later and pick up exactly where you left off.
Crystl automatically saves every session — on close and every five minutes while you work. Nothing is lost, even if Crystl quits unexpectedly.
Browse past conversations with clear visual differentiation: your commands appear in bright text, Claude's responses in grey. Click any session to restore the full scrollback with all formatting intact.

- How long are sessions kept?
- Indefinitely. Sessions are stored locally and are never deleted unless you remove them manually.
- Can I search through past sessions?
- You can browse sessions by date and summary in the History panel. Full-text search is planned.
- Does history include tool outputs?
- Yes. The full terminal scrollback is preserved, including ANSI colors, tool outputs, and formatting.
- Where are sessions stored?
- In ~/.crystl/history/ as compressed files. They're local to your machine and never uploaded.
- Can I export a session?
- Not yet, but it's on the roadmap. For now, you can scroll back through any session and copy text manually.
