Come say hi on [Discord](https://discord.gg/uuSaa8NpY) — questions, support,
ideas, or just what you are using Lotti for.

**A distributed system of record for your memories — kept on your devices,
and nowhere else.**

Everything you capture in Lotti is a memory: a voice note, a screenshot, a
conversation, a photo from a birthday party, an hour of focused work, the
journal entry you spoke into your phone last night. Lotti keeps those memories
on your own devices and syncs them between those devices with end-to-end
encryption; no cloud ever holds a readable copy. On top of that record sit
applications — tasks, relationships, goals, events, projects, a daily journal —
most of them looked after by a personal AI agent that reads what you recorded and
proposes what to do next. Agents propose; you decide. Your memories are not
rewritten behind your back, not even by the agents that work for you.

macOS · Linux · Windows · iOS · Android. Flutter and Dart, GPL-3.0, in
development since 2016.

I have tracked around 11,000 hours of my own work in it since 2022.

     if a case id is ever renamed, these links need renaming with it. -->

## The vision: a system of record you own

Most personal software treats your life as content to be stored on someone
else's computer and mined. Lotti starts from the opposite premise: your
memories are a *record*, and a record is only worth something if it is
complete, unaltered, and yours. Four principles follow from that.

### 1. Your memories live only on your devices

There is no Lotti cloud, no Lotti account, and no ser
