PlayTrackr

What it does

Unlike Chrome extensions that only work inside YouTube (and break with updates), PlayTrackr is a standalone web app – no install needed, works on any device/browser. Standouts: Group playlists into customizable Projects (learning roadmaps) Distraction-free Focus Mode with auto-progress tracking as you watch Timestamped notes + deep analytics Privacy-first (local data + optional encrypted cloud sync) Truly free start: no signup, instant import Built for serious learners who finish courses

Turn scattered playlists into a focused learning system. Track progress, organize courses, and never lose your place again.
