YouTube Chapter Extractor

A chapter extractor pulls a video's chapter list — the timestamped outline creators define in descriptions (0:00 Intro, 2:15 Setup…) that YouTube renders as named player segments — out as clean, copyable text.

Chapters are the video's table of contents, and extracted as text they become usable outside the player: notes, summaries, research spreadsheets, and the content-structure intel of how successful videos in a niche organize themselves — pacing, segment lengths, hook placement — readable at a glance instead of scrubbed for.

Paste a video URL and get its chapters as a text list — timestamps and titles, ready to copy.

What extracted outlines feed: study notes from lecture/tutorial videos (the chapter list IS the skeleton — annotate under each heading), content research (extract chapters from your niche's top 10 videos and the winning structure pattern emerges: how long intros run, how many segments, where the payoff sits), your own reference index of long videos you revisit, and planning documents — a competitor's chapter structure is a proven outline to adapt, not copy.

Creator-side takeaways from any chapter study: intros on winning videos are brutally short (15–45 seconds before content), segments run 2–5 minutes, and chapter titles are written as mini-hooks ("The Mistake Everyone Makes") rather than labels ("Section 2") — because chapter titles show on hover and in search, doing thumbnail-adjacent work.
