Overview
existence-trace is an open-source journal companion that keeps everything in plain text files in your own folder. You write a few lines a day or import old diaries, and each day it writes a report on mood, stability and growth. When it is unsure about you, it asks one question with evidence, and your answer becomes a rule; whenever a rule changes a report it saves a before-and-after receipt, and a weekly check fails if a rule was never applied. It works with the AI model you choose. You get daily journal reports and a record you can check of how your answers shaped them.
