DayTrail

DayTrail is a local-first AI work memory tool that quietly records metadata from the apps, terminals, and editors you use throughout your workday. Instead of capturing full screenshots or keystrokes, it logs lightweight activity metadata — which files you touched, which commands you ran, which URLs you visited — building a searchable timeline of your day. When you lose context after a meeting or an interruption, DayTrail lets you retrace exactly what you were working on and how you got there. Everything stays local by default, so your data never leaves your machine. The open-source architecture means you can inspect, extend, or self-host the entire pipeline. For developers and power users who juggle multiple projects and deep work sessions, DayTrail acts as an external memory layer that reduces the cognitive cost of context switching.
