Does it work on any video?

Any public video that has captions, which is the overwhelming majority since YouTube generates them automatically. Videos with no speech, or with captions disabled by the uploader, cannot be summarised — there is simply no text to read.

How accurate is it on auto-captions?

Auto-captions mistranscribe names, jargon and accents, and the summary inherits that. It is told to read through obvious errors rather than quote them, but for anything you intend to rely on, check the claim against the video itself.

Is there a length limit?

Roughly an hour of speech per video. Longer videos are summarised from the first hour rather than refused, which keeps a two-hour podcast useful instead of erroring.

Do I need an account?

Not to summarise. Paste a link and read the result, no signup and no email. An account is only needed if you want the video made; rendering it uses credits.

Can I summarise the same video twice?

You can, and the second time is instant. Results are cached per video for a week, since a video's transcript does not change.

Can I republish the video I make from it?

The script is original narration built from the idea, not the creator's words re-cut, so what you generate is yours to post. Re-uploading the source video itself is a different thing entirely, and not something this does.

Q: What is the short script for?

Most people summarising a video are mining it for their own content. Alongside the summary you get a 45-second script built from the single most interesting idea in the video, written to be read aloud — and one button that turns it into a finished vertical video.

Paste a link and get the summary, the specific takeaways, and a short script built from the best idea in it.

Summarising is research, not the goal

Almost nobody summarises a video for its own sake. They are deciding whether it is worth an hour, or mining it for something they can make. The summary answers the first question in about ten seconds.

The second is the interesting one. A long video usually contains one idea that would travel on its own, and finding it is most of the work of short-form content. That is why the short script sits next to the summary rather than behind a paywall — it is the part that becomes a video.

What it will not do is let you republish someone else's video. The script is original narration built from the idea, not the creator's words re-cut, which is the distinction YouTube's reused-content rules turn on.

Frequently asked questions

Everything about summarising YouTube videos

It reads the video's caption track — the same text YouTube shows when you turn subtitles on — and summarises that. Nothing is downloaded or re-uploaded, which is why it comes back in seconds rather than minutes.
