# matthiasn/lotti

A private logbook with a staff of personal AI assistants. Agents read what you record and propose what to do next — you approve the changes. End-to-end encrypted sync between your own devices — servers only ever see ciphertext. Local AI optional.

## What it is
Lotti is a private, local-first logbook app for journaling, task management, time tracking, habits, and health data, with a staff of personal AI assistants that read your records and propose next steps for your approval. It syncs end-to-end encrypted between your own devices, so servers only ever see ciphertext, and AI usage is optional with a recommendation toward European open-weight model infrastructure.

## Use cases
- keep a private journal with voice notes and photos
- track time spent on tasks and projects
- manage tasks and planned time blocks separately from actual work
- record habits and health data locally
- get AI summaries and suggested next steps from a personal agent
- sync notes privately across devices with end-to-end encryption

## When to choose
- you want a privacy-first journal and time tracker that never stores readable data on servers
- you want AI assistance that proposes changes but always waits for your approval
- you need one cross-platform app for journaling, tasks, habits, and health data
- you prefer local-first storage with optional, self-controlled AI

## When to avoid
- you need team collaboration or shared task boards
- you want a simple hosted to-do app with zero configuration
- you rely on cloud AI services like OpenAI by default rather than self-managed models

## Facets
- artifact type: application
- maturity: active
- function: speech-recognition, nlp, agent-framework, chatbot, scheduling
- domain: developer-tools, privacy, self-hosted, artificial-intelligence, healthcare
- platform: windows, cross-platform
- tags: journaling, time-tracking, task-management, local-first, end-to-end-encryption, flutter, ai-agents, health-tracking, habits, macos, linux, ios, android
