How it works

  1. Paste the link

    A watch URL, a youtu.be link or a Short. Public videos only.

  2. Choose what to read

    Words only uses the captions, or the audio when there are none. Add the screen for slides and demos.

  3. Skim and jump

    Every point has a timestamp. Click one to check the moment it came from.

A summary with timestamps

Sample

A talk on a monthly budget you can keep: track first, cut one category, automate the rest.

  • Track every expense for one month before you change anything. 1:35
  • Cut the one category that surprised you most, not all of them. 10:12
  • Automate savings on payday so the decision is made once. 23:00
  • Review once a quarter, not every week. 35:05

Chapters

  • 0:00Why budgets fail
  • 1:35Track before you cut
  • 10:12Choose one category
  • 23:00Automate savings
  • 35:05Quarterly review

Works when there are no captions

A summarizer that reads only the captions YouTube already has gives up when a video has none, or summarizes the mistakes in rough auto-captions. Scribiz checks the captions first. If they are missing or poor, it listens to the audio and summarizes that. The result says which one it used.

Pick Words and screen when the point is on the slides, as in a lecture, a product demo or a tutorial. Slide titles and on-screen text are then part of what gets summarized. For a plain talk, Words only is enough and costs less.

Timestamps you can check

A summary is only useful if you can tell it is right. Every key point and chapter is matched to a segment of the transcript, so the timestamp is where the words were said, not a number a model guessed. Click it and the player jumps there.

A model still writes the summary, so it can leave things out. Open the timestamps for the points that matter to you. Quotes are meant to be exact, so check them against the transcript.

Chapters come as a list you can paste into a video description. For the full text, use the YouTube transcript page.

Long videos and other sources

Long videos are transcribed in parallel chunks, then summarized from the whole transcript, so the end gets as much weight as the start. The length you can run depends on your plan, and minutes and billing explains what each mode costs.

Not on YouTube? The video summarizer takes TikTok, Instagram and files such as Zoom recordings. If you work in Claude or Cursor, the MCP server lets your agent ask for the same summary. Can ChatGPT or Claude watch a YouTube video explains why a pasted link is not enough.

Yes, on the result page. A question uses a tenth of a minute, answers point to timestamps, and without an account you get five a day. Minutes and billing lists every mode.

Yes. Scribiz detects the spoken language, and the summary and chapters are written in the language of the transcript. It does not translate.

Summaries are written by a model and can be wrong or leave things out. Each point links to a time so you can check it. Quotes are meant to be exact, so check them against the transcript.
