Lotti.app

Tasks, habits, tracked time, voice notes and journal — kept on your own devices, summarised by AI assistants you choose, and never uploaded anywhere in readable form.

Lotti is a private logbook for the work you actually did.

It records what you meant to do and what actually happened, and keeps them as separate facts: tasks with checklists and planned time, the hours you really tracked against them, voice notes and photos from the day, journal entries, habits, and health data. Everything lives in a local database on your own devices.

WHAT IT DOES

• Tasks — plan work with checklists, due dates, priorities and estimates, and see what is blocked by what. • Time tracking — start a timer on the task you are on; every tracked session stays attached to it. • Voice notes — record, transcribe, and let the app turn a note into checklist items and task updates you approve one by one. • Habits — daily and weekly routines with a completion history that is honest about the imperfect weeks. • Journal — notes, photos and audio in one dated stream, linked to the tasks they belong to. • Insights — where your tracked hours went, by category and over time. • Health — import steps, sleep and workouts from Apple Health to see them next to your own records.

AI ASSISTANTS, ON YOUR TERMS

Lotti can hand each task or area to a persistent assistant that reads what you record, keeps the mess summarised, and proposes the next step. Proposed changes wait for your approval — nothing is written to your journal until you confirm it. AI is optional: you connect a provider under your own key, and the route Lotti recommends is European infrastructure running open-weight models. No Lotti account is needed, and there is no Lotti server.

PRIVATE BY CONSTRUCTION

• No telemetry, no analytics, no crash reporting. • Local-only by default. Your data is in SQLite databases and files on your device, exportable at any time. • Optional sync between your own devices is end-to-end encrypted via Matrix; the relay holds ciphertext only. • Optional AI is routed per category to the provider you choose, under your own key.

Lotti is free and open source (GPL-3.0), in development since 2016, and also available for mac.
