    FAQ

    Everything you might be wondering

    How do I add chapters to a YouTube video?
    Paste the video URL above and press Generate chapters. The tool reads the transcript and gives you a ready-to-paste list of timestamps and titles. Copy that block, open your video in YouTube Studio → Details, and paste it into the description — YouTube turns it into clickable chapters automatically. It's the fastest way to add chapters to a YouTube video without any editing software.
    What are YouTube's rules for chapters?
    Your description must contain a list of timestamps where the first one is 0:00, there are at least three timestamps in ascending order, and every chapter is at least 10 seconds long. This tool formats the block so it follows those rules.
    Is it really free?
    Yes. It's free and needs no account. Because it runs on a shared free queue, generating chapters can take a minute or two. For instant results, priority processing, bulk channels, and unlimited runs, use the Claras Chrome extension.
    Do chapters help SEO and discovery?
    Chapters make a video easier to navigate, which improves watch time. They also let YouTube and Google surface individual sections as key moments in search, giving your video more ways to be found.
    Does it work on every video?
    It works on public videos that have captions or a transcript. Private, age-restricted, or caption-less videos may not be processable.

    How to add chapters to a YouTube video

    A YouTube chapter generator reads a video's transcript and turns it into a list of timestamps and titles — the YouTube chapters that appear as clickable segments on the progress bar. Paste a link, and this free tool gives you a ready-to-paste chapters block plus a clickable list, so you can add chapters to any video in seconds instead of scrubbing the timeline by hand.

    How to add chapters to a YouTube video

    1. Copy the video URL from the address bar or the Share button.
    2. Paste it into the chapter generator at the top of this page and press Generate chapters.
    3. Press Copy chapters to grab the ready-to-paste block of timestamps and titles.
    4. Open the video in YouTube Studio → Content → Details and paste the block into the description.
    5. Save. YouTube turns the timestamps into clickable chapters within a few minutes.

    What are YouTube's rules for chapters?

    YouTube only shows chapters when your description meets three requirements, and this tool formats the block to satisfy all of them:

    • The first timestamp must be 0:00.
    • There must be at least three timestamps, listed in ascending order.
    • Each chapter must be at least 10 seconds long.

    Do chapters help with SEO and discovery?

    YouTube chapters improve the viewing experience — people can skip to the part they want, which tends to lift watch time and retention. They also give search engines more to work with: YouTube and Google can surface an individual chapter as a key moment in results, so a single video can rank for several different queries.

    Is there a limit?

    This free tool is meant for occasional use and runs on a shared queue, so chapters can take a minute or two and there's a small daily cap. If you publish often — or want to chapter a whole channel or playlist at once, instantly — the Claras Chrome extension removes the wait and the limits, and generates chapters right on the YouTube page.
