Open-source private logbook with a local agentic layer Lotti is an open-source personal logbook — tasks, time recordings, voice notes, transcriptions, journal entries, habits, and health data — paired with an agentic layer of long-living AI agents that observe, suggest, summarise, and nudge. The agents run on your machine. With a powerful enough device, the model they call can run locally too — meaning your data never has to leave the device at all. On lighter hardware, or when you need to save battery, you keep the same agentic experience and route inference to a cloud provider you choose, on a per-category basis. No accounts, no telemetry, no cloud storage. End-to-end encrypted multi-device sync runs over Matrix using Vodozemac (Rust) for Megolm crypto; the homeserver you bring relays only ciphertext between your own devices, and encryption keys reach only devices you have verified. Your logbook is an ordinary SQLite file on your own disk, readable without Lotti, so there is nothing to export and nothing to unlock. Get support and join the Lotti community on Discord via the Contact link. What it does: Long-living AI agents (mission, soul, report directive) that read your logbook, propose changes, and only act after you approve Two-database architecture: a strict separation between your facts (the user database) and what the agents think (the agentic database), enforced on disk Run reasoning-capable models locally via oMLX or Ollama (e.g. Qwen 3.6 35B A3B, a Mixture-of-Experts model with ~3B active parameters) — or use Gemini Flash, OpenAI, Anthropic, Mistral, Melious.ai, or any OpenAI-compatible cloud provider, on a per-category basis Local voice transcription with Whisper or Voxtral; cloud transcription via Gemini, OpenAI, Mistral, or Melious.ai AI-generated cover art for tasks via Nano Banana Pro on Gemini, OpenAI, or Qwen, and Flux on Melious.ai Both the logbook and the agentic state sync end-to-end encrypted Habit tracking with success/fail/skip completion types, custom measurables, and dashboards Bring-your-own API keys for cloud providers, choosing per category where inference happens — EU-hosted, US, Chinese, or entirely on your own machine Usage & Impact: tokens and requests for every cloud AI call, broken down by category and model, plus cost, energy and CO2e wherever the provider reports them (currently Melious); local inference is not measured Time recording kept separate from planning, so what you meant to do and what actually happened stay distinct facts Additional information:Developer: Matthias NehlsenLicense: GPL-3.0-onlyVersion: 1.0.4
