YouTube chapters
YouTube chapters generator: timestamps and titles from the transcript
A YouTube chapters generator reads the transcript and returns a ready set of timestamps: paste a video link, press Chapters, and get one line per topic in the “00:00 Title” form that YouTube accepts in a description, free for any video with captions. Below are the steps, a sample, the rules for showing them, how many a video gets, how to paste the lines, and what it can’t do.

How to generate YouTube chapters in four steps
Generating chapters takes four steps, and the AI starts only at the second click, not before.
- Paste the link. Put the address in the field at the top of the page, or drop a recording from your device instead.
- Open Chapters. When the transcript appears, press the Chapters & timecodes tile in the Understand group. Nothing is generated before that click.
- Read the list against the video. Each chapter has a start time; click it and the player jumps to that moment, so a wrong boundary is easy to spot.
- Copy it for the description. Press Copy for YouTube description, paste the lines into the description and save.
Beside the result sits the full YouTube transcript with timestamps, so any title can be checked against the exact words spoken at that moment.
What the generated list looks like
A generated list is plain text: a line per chapter, each starting with its time and followed by a short title.
Illustrative output for a 25-minute video, not a real recording:
00:00 What you need to start
02:40 Choosing and grinding beans
08:15 Dosing and tamping
14:05 Pulling the shot
19:30 Fixing sour and bitter shotsIn the app each line also carries a short note on what the chapter covers, and a button that plays from that time. The copy button leaves the notes out and gives only the lines above, because that is all a description needs.
YouTube’s rules for chapters, and how the list meets them
YouTube turns a description into chapters only when three conditions hold, and each list is built to satisfy them.
- The first timestamp is 00:00. The first chapter is always pinned to the very start.
- There are at least three timestamps. The generator asks for three or more; if a short video yields fewer, a hint under the copy button says YouTube won’t show them.
- Each chapter lasts at least 10 seconds. A shorter one is merged into the previous.
- Times ascend in a single format. Past an hour every line switches to
0:00:00,1:04:10, so the list never mixes forms.
The times themselves are never guessed. The AI picks a line of the transcript where a topic starts, and the server writes the time of that line, so a chapter can’t land between two sentences.
How many chapters a video gets
The generator asks for roughly a chapter per five minutes, between 3 and 20.
| Length | Chapters requested |
|---|---|
| under 1 minute | none: too short, nothing is spent |
| 1 to 17 minutes | 3 |
| 25 minutes | 5 |
| 1 hour | 12 |
| 100 minutes or more | 20 |
A long recording is cut into parts before the AI reads it, and the results for each part are joined, so the list covers the last hour as well as the first.
How to put timestamps into a YouTube video description
Open the video in YouTube Studio, paste the copied lines into the Description field and save.
- Paste the lines as a single block, a chapter on each, starting with 00:00.
- Reopen the watch page after saving: the progress bar is split into named segments.
- For notes outside YouTube, download it as Markdown: each time then becomes a
youtu.belink that opens it at that second.
Viewers who want the words rather than the outline can open the same video’s transcript with a timestamp on every line; it is free and needs no AI.
Generator, manual list or YouTube’s automatic chapters
The four routes differ in who decides the boundaries and how much of the work remains with you.
| Way | What you do | What you get |
|---|---|---|
| By hand | Play it through, note each time, type each line | Boundaries exactly where you want them |
| YouTube’s automatic chapters | Switch the option on in YouTube Studio | Sections YouTube chooses, for videos it supports |
| Timestamp formatters | Supply the times and titles yourself | A correctly formatted list |
| This generator | Paste the link and press Chapters | Times and titles from the transcript, as text you can edit |
The generator works from the words, so it suits talks, tutorials, lectures and interviews. A video with little speech gives it little to go on, as with the notes in turning a video into structured notes.
Chapters, key moments or notes: which tile to press
Chapters divide the whole recording into sections, while key moments pick five to ten single points and quote the line that proves each.
- Chapters: the talk in order, for a description or for navigating a long recording.
- Key moments: the highlights, each with a quote, for deciding what to rewatch.
- Detailed notes: the content itself under topic headings, for studying.
All three are tiles in one list; the overview of AI actions for video compares them, and the lecture summarizer shows the same transcript used for revision.
What’s free and what uses minutes
Chapters for a captioned YouTube video are free with no sign-up; a file or an uncaptioned clip is transcribed first, from $0.033 per minute.
- Captioned YouTube video: chapters, key moments, a summary and every other AI action at no cost. On a day of very high demand, free AI may pause until the next day.
- First recording without captions: free with no account, in full up to 10 minutes, the first 10 minutes of a longer one.
- After that: one minute of balance per minute of recording, with every AI action on it included; signing up adds 10 minutes of transcription.
What a YouTube chapters generator doesn’t do
This generator produces text and nothing more, so it never changes anything on YouTube.
- No upload to your channel: you paste the lines into the description yourself.
- No reading of the picture: a silent screencast or a slideshow over music has no speech to divide.
- No chapters for a clip under a minute.
- No standalone timestamp-link maker: the Markdown download links each chapter, but there is no field for building a link to one chosen second.
- No guarantee that YouTube displays the result: that depends on the three rules above and on the platform.
Files from a device are accepted too; the guide to transcribing audio with timestamps covers the transcript side of that route.
Frequently asked questions
Is the YouTube chapters generator free?
Yes, for any video with captions: the Chapters tile and every other AI action on it are free, with no sign-up. A file or an uncaptioned clip is transcribed first, from $0.033 per minute, and the first such recording is free up to 10 minutes.
Do I have to sign in to YouTube or give access to my channel?
No. The generator reads the public captions of the link you paste and never touches your channel. You copy the finished list and paste it into the description yourself.
Can I make chapters for a video that isn’t mine?
You can generate a list for any captioned video and use it as a map of the talk. Only the owner can put chapters into the description, so for someone else’s upload it stays a reading aid.
How many chapters will I get?
About a chapter per five minutes, between three and twenty: roughly 5 for a 25-minute video, 12 for an hour. A clip under a minute is too short and returns nothing.
Why doesn’t YouTube show my chapters?
Usually one of three rules is broken: there are fewer than three timestamps, the first one is not 00:00, or a chapter is shorter than 10 seconds. The generator starts the list at 00:00 and merges any chapter under 10 seconds into the previous one.
Can it work on a recording without captions?
Yes. Whisper speech recognition writes the transcript first, for one minute of balance per minute of recording, and the Chapters tile then costs nothing extra.
Can I edit the chapter titles?
Yes, after you paste them. Titles are capped at 60 characters and written in the language of the speech, so a rewrite in the description editor is the normal last step.
