How to turn YouTube comment timestamps into chapters

On any long video, viewers have already done the chapter marking for you. It is scattered across thousands of comments in no useful order, which is the only reason it goes unused.

The short version

  1. Load the videoPaste the video URL so every comment and reply is available to scan.
  2. Open ChaptersEvery timestamp mentioned in the comments is collected, with how many people cited each moment.
  3. Filter out the noiseShow only moments mentioned twice or more if a single stray mention is not worth a chapter.
  4. Copy into the descriptionOne button produces the list in the format YouTube expects, starting at 0:00.
Open the tool

Why the comments are a better source than you are

You know where the sections are. Your audience knows where the good bits are, and they are not always the same thing. “The part at 4:12” gets repeated because several people independently decided that moment mattered — which is a stronger signal than any structure planned before the edit.

It also costs you nothing. The work is already done and sitting in the comment section.

How the moments are grouped

People do not agree to the second. One says 4:10, another 4:12, another 4:13 — one moment, three numbers. Mentions within a few seconds of each other are treated as a single moment, and the link points at the value most people actually cited rather than at an outlier.

Both formats are read: 4:12 as minutes and seconds, 1:02:03 as hours, minutes and seconds. Numbers that merely look like times — a score, a ratio, a price — are left alone.

Getting it into YouTube

YouTube turns a description into chapters only when the rules are met: the first entry must be 0:00, there must be at least three entries, and each chapter must run at least ten seconds. The copy button produces a list in that shape and adds the opening 0:00 when your audience did not supply one.

Paste it into the description, then edit. The captions come from the most-liked comment at each moment, which is a good starting point and rarely the final wording — a chapter reading “this part is insane” wants rewriting before it ships.

Where this works and where it does not

Timestamps show up densely on tutorials, podcasts, interviews, music and long-form commentary. A three-minute video will produce nothing, and that is correct rather than a failure — there is nothing to point at.

The index is built from the comments loaded, so loading more finds more. Sorting by mentions rather than by time answers a different question: not “what are the chapters” but “which single moment did the audience care about most”, which is useful when deciding what to clip.
