Local-first
Open, edit, and close documents with zero network in the critical path. Your device is the source of truth.
Deterministic sync
Offline changes queue and reconcile automatically via CRDTs — concurrent edits merge without data loss.
Time travel
Capture versions and restore any point in history safely, without corrupting collaborators' state.
