YouTube Summarizer FAQ

No. Paste a link and go. An account only matters once you want history that follows you between devices, or the free limits lifted.

All of them: youtube.com/watch?v=…, youtu.be/…, Shorts, embeds, live replays, youtube-nocookie.com, and a bare eleven-character video id pasted on its own.

Usually a few seconds. Long videos take longer because there's more transcript to read — an eight-hour conference stream is a minute or two, not a few seconds.

Yes. Share a video to your browser, paste, and you get the same four views. The layout collapses to a single column on small screens.

If YouTube has no transcript — auto-generated or human — we transcribe the audio ourselves on Pro. On Free you'll get a clear message rather than a summary of nothing.

Thirty minutes on Free. On Pro there's no ceiling — eight-hour conference streams and full audiobook readings both work, they just take a little longer.

Every claim stays anchored to the timestamp it came from, so you can check it in one click. That's the honest answer: a summary is a starting point, and we make verifying it fast rather than asking you to take it on faith.

Two things to know. Where a video is confidently wrong, the summary will faithfully report a confidently wrong argument — accuracy here means "accurate to what was said". And auto-generated captions mis-hear names and technical terms, which flows downstream.

Unlisted links work if you have the URL. Private videos don't — we can only read what your link can reach.

Music videos, silent timelapses, and footage where the meaning is purely visual have nothing for a transcript-based tool to work with. You'll be told rather than handed something invented.

38, in both directions — you can summarize a Japanese lecture into English or an English keynote into Spanish. Technical terms are kept in their original form alongside the translation rather than guessed at.

We never store video files. Without an account, your recent summaries live in this browser's local storage and nowhere else — clearing them here clears them, full stop. With an account, they're stored so they can sync, and you can delete them at any time.

No to both. The business model is subscriptions. What you choose to summarize is a fairly intimate record of what you're trying to learn, and it isn't for sale. See the privacy policy for specifics.

Without an account: the "Clear" button next to your recent summaries. With one: delete your account from settings, which removes your history too. Details in the privacy policy.

Yes — no card, no trial clock, no end date. Five summaries a day covers most people who watch a couple of long videos a week.

Yes, from settings, without emailing anyone. Yearly plans are refunded pro rata for the months you haven't used.

Yes — contact us from your institutional email. Course-wide and departmental licences work the same way.

On the Team plan. Post a link, get structured JSON back — the same TL;DR, takeaways, chapters and notes the interface uses. See the team page.

No. This is an independent tool that reads publicly available transcripts. YouTube is a trademark of Google LLC.

Summaries are derived from someone else's work, so normal copyright and fair-use rules apply to what you do with them. Quoting a few takeaways with attribution and a link is generally fine; republishing a full transcript as your own content is not. The terms cover this.
