The application stores data locally in a single JSON file and requires no internet connection or account. It supports basic Trello import and granular or full exports for backups. Installers are available for Windows, macOS, and Linux, with macOS installation also available through Homebrew. The repository documents Tauri-based development and production build commands.

Lotti is a local-first personal logbook that separates planned tasks from records of completed work. Users can create tasks with checklists, priorities, estimates, due dates, labels, statuses, and linked context; record time, notes, images, audio, measurements, and journal entries; and organize information with categories and labels.

The application includes habit tracking, time analysis, speech transcription, dashboards, search, and optional task-specific AI agents that summarize records and propose changes for approval.
