Study Buddy for YouTube

About

Study Buddy for YouTube : study from playlists and videos faster

Study Buddy for YouTube adds two tools right in your browser

1. Playlist duration
On any YouTube playlist page, open Study Buddy for YouTube to see how long the full playlist takes to watch at 1×, 1.25×, 1.5×, and 2× speed. Useful for deciding whether a course, podcast series, or binge list fits your schedule.

2. AI chapters
On any video, open Study Buddy’s AI chapters to get a clear list of sections with timestamps. If the creator already added YouTube chapters, Study Buddy shows those automatically. Otherwise, chapters are generated from the video transcript so you can skim structure before you commit to watching.

Click any chapter to jump to that moment in the video.

Smart and lightweight
Works on standard YouTube playlist and watch pages
Caches results locally so repeat visits load faster
Study Buddy uses YouTube’s own chapters when available, AI only when needed

Privacy
Transcripts are read from YouTube in your browser. For AI chapter generation, video metadata and transcript text are sent to the Study Buddy backend to produce chapters. Playlist duration and native YouTube chapters stay on your device. See the privacy policy in the listing for details.

Permissions
Storage — save Study Buddy settings and cache playlist/chapter data locally
Tabs — seek the active YouTube tab when you click a chapter
YouTube access — read page information needed for playlist duration and chapters

Study Buddy for YouTube is made for students, learners, and anyone who watches long-form YouTube content and wants a clearer map before they press play.
