YouTube Chapters Generator
Paste your script and get a timestamped chapter list you can drop straight into your YouTube description, with titles taken from the sections you already wrote.
0 words — at least 100 needed
Only used to keep the chapter names on topic. The chapters work without it.
Every timestamp is your word count divided by this pace. Measure your own delivery with the talking-speed test if you want a number from your own voice instead of a preset.
Chapters done? Check the script itself, free
Paste the same draft. You get hook, structure and pacing scores and the one issue costing it the most, quoted from your own lines.

What you get
A chapter block in YouTube's own format
One line per chapter as MM:SS Title, the first line always at 00:00, between 4 and 12 chapters depending on how many sections your script has. Copy the block as-is or delete the lines you do not want.
Titles drawn from your script, 45 characters or fewer
Each name comes from what that section actually says, kept short so it is not truncated in the player. Chapter names are plain text in your description, so you can rename any of them before you publish.
Start times computed at your pace
Pick 130, 150 or 175 words per minute and every timestamp is recalculated from your word count at that pace, so a slower edit does not leave the chapters bunched at the front.
How timestamps are computed
Every start time is words ÷ wpm, taken from a running word count rather than from the clock: the generator adds up the words that come before a section, divides that total by the pace you chose, and writes the result as MM:SS. A section that starts after 450 words at 150 words per minute is timestamped 03:00 — 450 ÷ 150 minutes.
The AI reads your script only to decide where one section ends and the next begins, and to name them. It never guesses the numbers, so changing the pace above moves every timestamp by the same arithmetic instead of leaving the old times behind. Use 150 words per minute unless you have measured your own delivery; the talking-speed test gives you that number in about a minute, or use words-to-minutes for a runtime estimate.
Because the times come from word count, a script read slowly, a demo with no narration, or an edit that trims a section all shift the real timestamps. Check the first couple of chapters against your recording and correct them in the description before you publish.
Frequently Asked Questions
How accurate are the generated timestamps?
They are arithmetic, not transcription. The generator counts the words in each section of your script and divides that count by the speaking pace you selected, so a 150-word section at 150 words per minute lands at 1:00. Real delivery drifts with pauses, demonstrations and edits, so treat each timestamp as a starting point: record, scrub through, then nudge the ones that land early or late.
Does YouTube need at least 3 chapters, each 10 seconds long?
Yes. YouTube asks for at least three chapters, the first one starting at 0:00, and each chapter running at least 10 seconds. This tool always writes the first chapter at 00:00 and returns between 4 and 12 chapters, but check the shortest ones: a section under 10 seconds is a title to merge into the chapter next to it rather than a chapter YouTube will accept.
Can I edit the chapter titles?
Yes. Chapters are plain text in your description box, so the titles are yours to rewrite before or after you publish, and the timestamps are just numbers you can type over. Keep names to about 45 characters or fewer so they are not cut off in the player, and use the words a viewer would scan for.
Is my script stored?
Your result is stored so the link keeps working: the chapter list, the tool, the optional video title, and your email only if you entered one, because that address is what unlocks extra runs the next day. Nothing is published and no other visitor can open your result. The script you paste is not part of the shared result page, and nothing is sent to YouTube: you copy the block into your own description.
Do chapters help retention?
Chapters are a navigation aid: viewers can see the structure of a long video, jump to the part they came for, and key moments can appear as separate search results. That is the whole claim. We make no retention claim, because whether a viewer stays depends on the footage, the pacing and the topic, none of which a chapter list can promise.
