It remembers who you are.
Grounded in you.
Your life is scattered across a hundred apps. Your emails know your professional voice. Your texts know your humor. Your documents know your ideas. But nothing knows all of you. LifeTrace assembles every fragment into one complete picture.
Every day you create thousands of traces. Together, they tell the story of who you are.
The email you sent your coworker. The text you sent your mom. The notes you wrote at midnight. Each one captures a fragment of you — your voice, your thinking, your relationships. But they're trapped in silos. No system has ever held the full picture.
LifeTrace runs quietly on your machine, gathering traces from across your digital life and weaving them into a single, growing corpus — a holistic representation of who you are that gets richer every day. Not a backup. A living memory that an AI can draw from to think like you, speak like you, and remember what you remember.
How it works
Self-hosted. Open source. Bring your own LLM.
LifeTrace is a desktop app that runs on your Mac. Connect your data sources — Gmail, Calendar, iMessage, Apple Photos, Google Timeline, local files — and it syncs in the background, even waking up when your laptop does. From those traces it writes a daily journal, plots a map of where you've been, and answers questions through a chat that actually knows you. Your data never leaves your machine. Choose any LLM.

Scale your expertise
Let LifeTrace learn how you think, then deploy a digital version of yourself that answers questions and shares knowledge at scale.
Total recall for your life
