Course Tracker for YouTube

Turn any YouTube playlist into a course: progress bar, checkmarks, time left, and resume right where you stopped.

Turn any YouTube playlist into a course you can actually finish. Course Tracker adds a progress card to every YouTube playlist: checkmarks on each video, a progress bar, the real time left (computed from video durations), and a Resume button that reopens the exact video — at the exact second — where you stopped. FEATURES ✓ Progress bar and % complete on every playlist page ✓ One-click checkmarks to mark videos watched / unwatched ✓ Auto-marks a video as watched at 90% — no clicking needed ✓ “Time left” computed from real video durations ✓ Resume: jump back to the right video at the right second ✓ “My courses” popup: all your courses and progress in one place ✓ Completion celebration when you finish a course 🎉 ✓ Optional gentle reminder on browser startup to continue your course (off in one click) ✓ Light and dark theme support COMING SOON (Pro, small one-time purchase): timestamped notes with Markdown export, weekly goals & streaks, cross-device sync, custom courses. Open the ✨ Pro preview inside the extension and vote for what you want first. PRIVACY FIRST No account. No server. No AI. No analytics. Your progress is stored locally in your browser and never leaves it. Two permissions only: storage (save your progress locally) and notifications (the optional startup reminder, shown locally). HOW TO USE 1. Open any YouTube playlist page 2. Click “Track this playlist as a course” 3. Learn. Your progress takes care of itself. Made for self-learners who use YouTube as their classroom.
