A turn finishes
Codex, Claude Code, OpenClaw, OpenCode, or Hermes completes a task — maybe in a window you left an hour ago.
A note settles
It lands quietly beside the stones. No sound, no banner, no stolen focus — it waits until you look.
Click to trace back
One click walks you back to the exact terminal tab, window, or conversation the work ran in.
Never interrupts
Cairn has no window and asks for nothing. It reports that something finished; it never demands that you respond.
Everything stacks
Notes from the same agent and project gather into one stack. Expand it only when you need the rest.
Traces back
Open a note to jump back to the exact terminal tab, editor window, app window, or session where it ran.
Stay focused
Juggle less in your head. Cairn remembers where each task lives, so you can stay with the one in front of you.
