Lotti
A local-first logbook combines tasks, time tracking and journals with optional local or cloud AI and encrypted sync between your devices.

Lotti is a private logbook for people who want to keep their plans and a record of what actually happened together. It connects daily planning with personal notes and work history while keeping the underlying record on your devices.
- Tasks and context: Keep priorities, next steps, notes and evidence of completed work attached to a task.
- Daily planning: Turn a spoken or typed check-in into an editable day plan, with planned work kept distinct from actual time spent.
- Personal records: Capture voice notes, photos, screenshots and journal entries alongside time tracking, habits and health data.
- AI proposals: Optional agents review recorded context and suggest changes for your approval; they can fill an empty task title or language field without asking.
- Encrypted sync: Share your record between your own devices through a Matrix relay you can self-host or use through a hosted service. The relay receives encrypted content, though its operator can see connection and sync metadata.
Lotti is open source under GPL-3.0 and runs on macOS, Windows, Linux, iOS and Android. Your logbook stays on your devices, and you don't need a Lotti cloud account. AI is optional: local inference processes selected material on your machine or a configured local endpoint. Cloud inference sends the context you choose directly to your provider under your own account and API key; that provider's retention and data policies apply.
