YouTube Timestamp Generator: Chapters Ready to Paste
Paste the link to your video and the timestamp generator finds where each topic starts, then writes 4 to 12 chapters as "0:00 Title" lines. They follow YouTube's chapter rules, so pasting them into your description splits the progress bar into sections.
Download only videos you made or have permission to use. Tube Snip shows each video's license so you can check before you reuse it.
Understand any video without watching all of it
Each tool runs on the video you fetched. Costs are in credits; guests get a few free runs every day, and every account starts with free credits.

How to generate YouTube timestamps in 3 steps
- Paste the link to your video above. Public and unlisted videos both work, so you can add chapters before you publish.
- Open the AI tab and choose Chapters. The tool reads the video's captions, finds where the topic changes and writes chapter lines like "0:00 Intro" and "2:15 Setting up".
- Copy them into your description. Paste anywhere in the YouTube description and save. The chapters show on the progress bar within minutes.
A chapter run costs 3 credits. Without an account you get 3 free AI runs a day; a free account starts with 60 credits.
What you get
Here is the format, shown for an example 18-minute video about building a desk:
0:00 What we're building
1:20 Tools and wood list
3:45 Cutting the legs
7:10 Joining the frame
11:30 Sanding and oil finish
15:05 The finished deskThe first line is always 0:00. There are 4 to 12 chapters, and each title stays under 50 characters, so it fits on the progress bar and in the chapter list on phones.
YouTube's rules for chapters
YouTube only turns timestamps into chapters when all of these are true (YouTube Help: video chapters):
| Rule | Why it matters |
|---|---|
| The first timestamp is 0:00 | Without it, YouTube ignores the whole list |
| At least three timestamps | Two sections don't count as chapters |
| In time order | Out-of-order lines break the list |
| Each chapter is 10 seconds or longer | Very short sections are dropped |
The generator writes chapters that meet all four rules. Paste them as plain lines, one chapter per line, with the time first.
Timestamps or a timestamp link?
"Timestamp" means two things on YouTube, so here are both:
- Chapters (this tool): a list of times in your description that splits your own video into sections.
- A link that starts at a time: for sharing a moment of any video. On a computer, pause at the moment, right-click the video and choose Copy video URL at current time, or tick Start at in the Share box. On a phone, add ?t= and the number of seconds to a youtu.be link, for example ?t=95 for 1:35.
Tube Snip reads time links too: paste one and the clip cutter opens at that moment.
Where to paste your chapters
On a computer (YouTube Studio)
Open YouTube Studio → Content, click the video, paste the chapter lines into Description and click Save. A short line above them, like "Chapters:", is fine.
iPhone and Android (YouTube Studio app)
In the YouTube Studio app, open the video, tap the pencil, then Description. Paste the lines and tap Save. Copy them from Tube Snip on the same phone with the Copy button.
In a comment
Chapters only become clickable sections from the description. A comment with timestamps gives viewers clickable times, but no chapters on the progress bar.
Write chapter titles people click
The generator writes a first draft. A few minutes of editing makes chapters work harder:
- Say what happens, not "Part 2". "Fixing the wobble" beats "Section 4".
- Use the words people search. A chapter can show in Google results as a key moment, so name it the way someone would ask for it.
- Keep the intro short. If your 0:00 chapter is two minutes long, viewers skip it. Name it after the payoff instead: "What the finished desk looks like".
- Mark the answer. In a video built around one question, give the answer its own chapter. People will jump to it, and they will stay longer than if they gave up looking.
How the generator finds where chapters start
YouTube's captions come with a time on every line. The generator reads the whole transcript, looks for the points where the subject changes (a new step, a new question, a new product, a new part of the story) and names each section in a few words. It's told to start at 0:00, to keep between 4 and 12 chapters and to keep titles under 50 characters, which is why the output pastes straight in. Videos that already follow a clear structure, like "first, second, finally", get the most exact chapters. Rambling videos still get chapters, but check the start times by clicking them.
Chapters for different kinds of videos
These are examples of how chapter lists look for different formats, not real videos:
Tutorial
0:00 The finished result
0:40 What you need
2:10 Step 1: Prepare the surface
5:30 Step 2: First coat
9:15 Step 3: Sand and second coat
13:00 Common mistakesPodcast or interview
0:00 Who is our guest
3:20 How she started
14:05 The first big failure
27:40 What she'd tell her younger self
41:10 Rapid-fire questionsReview
0:00 Verdict in 30 seconds
0:30 Design and build
4:15 Battery test
8:40 Camera samples
12:20 Who should buy itNotice the review puts the verdict first. People who only want the answer get it, and many stay for the reasons.
For lectures, name chapters after the concepts, the way a student would look for them before an exam: "Supply and demand", "Price elasticity", "Worked example". For vlogs, name places and moments rather than times of day: "Arriving in Lisbon" tells viewers more than "Morning". For long streams uploaded as videos, chapters are the only way most viewers will ever find the good parts, so mark every highlight.
Common chapter mistakes
- A long "Intro" chapter. If 0:00 to 2:30 is called "Intro", people skip it. Shorten the intro in the edit, or give that chapter a real name.
- Chapters that are too fine. Fifteen chapters in an eight-minute video make the progress bar hard to use on a phone. Merge small steps.
- Vague names. "Part 1", "Part 2" and "Final thoughts" say nothing. Every chapter title should tell a stranger what happens in it.
- Wrong times after re-editing. If you trim the video in YouTube Studio's editor after adding chapters, the times shift. Run the generator again on the final version.
- Typing the times by hand. One wrong digit, like 1:65, and YouTube may ignore the line. Copy the generated list as it is, then change only the titles.
Do chapters help views and search?
Chapters don't change where a video ranks by themselves, but they help in three practical ways. Google can show a video's chapters as key moments in its search results, which gives your video more ways to be found for specific questions; Google's own video documentation says it prioritizes key moments set in the YouTube description. Viewers who came for one part find it instead of leaving. And people who rewatch a section, like a recipe step, come back to your video instead of searching again. The cost is a few seconds of pasting, so there's little reason to skip them on any video longer than a few minutes.
Chapters and YouTube's automatic chapters
YouTube can add automatic chapters to some videos when the creator hasn't. You can allow or block them in YouTube Studio in the video's settings. Chapters you write yourself always replace automatic ones, and they're usually better: you know which part matters. The generator gives you your own list in seconds, without scrubbing through the timeline.
Chapters inside downloaded videos
Chapters live in the description on YouTube, but they can travel with a file too. When you save a video with the YouTube video downloader, Embed chapters is on by default: the MP4 keeps the chapter marks, and players like VLC and QuickTime show them.
YouTube chapter generators: Tube Snip vs other tools
When we asked Google's AI Overview for the best YouTube timestamp and chapter generator in October 2026, it listed several small browser tools and general AI assistants. Here are the options we could verify, plus YouTube's own automatic chapters. Each tool's facts below were checked on its own website on 19 October 2026.
| Tool | What it is | Price | Install | Best for | Watch out for |
|---|---|---|---|---|---|
| Tube Snip | Web app | 3 credits a run: 3 free runs a day without an account, 60 credits with a free account | Nothing | 4 to 12 chapters with titles under 50 characters, starting at 0:00, from a YouTube link | Uses credits after the free runs; the video needs speech or captions |
| YouTube automatic chapters | Built into YouTube | Free | Nothing | Doing nothing: YouTube may add chapters by itself | Not every video is eligible, and you don't choose the titles |
| SocialCal chapter generator | Web tool | Free, no sign-up | Nothing | Checking a chapter list against YouTube's rules, from a link or a pasted transcript | Link mode has a per-visitor limit; the video needs captions |
| ScreenApp | Web app | Free account with 2 transcriptions (up to 45 minutes each); paid from $19/month billed yearly | Nothing | Chapters from a link or an uploaded file, before the video is on YouTube | The free plan covers 2 videos |
| Descript | Video editor (app and web) | Free plan with 100 AI credits a month; Hobbyist $16/month billed yearly | Desktop app or web | Creators who edit in Descript: chapters from the transcript while editing | A full editor, more than you need for chapters alone |
Pick by situation. For chapters from a video that's already online, Tube Snip or SocialCal. For a file you haven't uploaded yet, ScreenApp or Descript. If you don't mind YouTube choosing for you, leave automatic chapters on.
More tools for the same upload
- A full description: the description generator writes 150–300 words with chapters included.
- Titles: the title generator writes five titles under 70 characters.
- Tags: the tag generator writes 15 tags from the same video.
- A transcript: the transcript generator gives the full text with timestamps.
Why chapters don't appear, and the fix
| What you see | Why | Fix |
|---|---|---|
| Chapters don't show on the progress bar | The first line isn't 0:00, or there are fewer than three | Keep the generated 0:00 line and at least three chapters |
| Some chapters are missing | A chapter was shorter than 10 seconds | Merge it with the one before |
| "This video has no captions" | The video is too new or has no speech | Wait an hour after uploading, or add captions |
| "You have used today's 3 free runs" | The guest limit | Make a free account for 60 credits |
Who uses it
- Tutorial makers so viewers can jump straight to their step.
- Podcasters marking each topic or guest question in a long episode.
- Teachers splitting a lesson so students can revise one part.
- Reviewers giving the verdict its own chapter.
- Course creators linking each chapter from a lesson page, so students land on the exact explanation they need.
- Live streamers turning a three-hour stream upload into a list of highlights people can actually navigate.
The rules
Use the chapters on your own videos. Chapter titles describe your content, so keep them accurate; misleading chapter titles count as misleading metadata under YouTube's policies. Any footage you use in the video must be yours, Creative Commons or used with permission.
Questions about this tool
How do I add timestamps to a YouTube video?
Paste the video link here, run Chapters, copy the lines and paste them into your video's description in YouTube Studio. The first line must be 0:00.
Is the timestamp generator free?
You get 3 free AI runs a day without an account. A chapter run costs 3 credits, and a free account starts with 60 credits.
Why don't my YouTube chapters show?
YouTube needs a 0:00 first line, at least three timestamps in order, and chapters of 10 seconds or more.
How many chapters should a video have?
Enough to mark each real change of topic. The generator writes 4 to 12, depending on the video's length and structure.
How do I share a YouTube link that starts at a certain time?
On a computer, right-click the video and copy the URL at the current time, or tick Start at when sharing. On a phone, add ?t= and the seconds to the link.
Can I add chapters before publishing?
Yes. Upload the video as Unlisted, wait until YouTube has made its captions, then paste the link here.
Should I write chapters for short videos?
Chapters help most on videos longer than a few minutes, where viewers look for one part. Each chapter must be at least 10 seconds, so very short videos rarely need them.
Can I edit the generated chapters?
Yes. Keep the times and change any title you like. Titles under 50 characters fit best on phones.
Do chapters stay in downloaded videos?
Yes, when you download with Tube Snip's video downloader and Embed chapters is on. VLC and QuickTime show the chapter marks.
Before you download
Why do some downloaders give me HD video with no sound?
In HD, YouTube serves picture and sound as two separate streams. Tube Snip downloads both and joins them, so every file in the Video tab plays with audio.
Can I paste just the video ID?
Yes. Paste the 11 characters after v= and it works the same as a full link. Shorts links, youtu.be links, embed links and links with a start time all work too.
How do I share a video from the YouTube app?
Install Tube Snip from your browser menu ("Add to Home screen" or "Install app"). Then in the YouTube app tap Share and pick Tube Snip; the video opens here, ready to download or summarise.
What are credits?
Credits pay for AI work. A transcript costs a few credits and a script blueprint costs more; the table above shows each tool. Downloading never uses credits. Unused monthly credits do not roll over; credit packs never expire.
Is downloading YouTube videos allowed?
Download your own videos and videos you have permission to use. Each result shows the video's license. Creative Commons videos can be reused with credit; standard-license videos need the creator's permission. We remove videos after valid copyright requests.
Which AI models do you use?
We route each tool to the model that does it best, from providers like Anthropic, OpenAI and Google. Best quality uses a stronger model and costs twice the credits.
