Free YouTube video summarizer

Paste a YouTube link. Get a structured AI summary and the full transcript, free, with no signup.

Free · No signup · Works with any public video that has captions

  • A structured summary

    Sections, key points and takeaways, not a wall of text.

  • The full transcript

    Every caption, searchable and grouped by time.

  • A page you can share

    One link for your notes, a group chat or a class.

This tool gives you the summary. LunaNotes gives you the rest.

LunaNotes is an AI note-taking app: bring a video, a PDF, an audio file, a meeting or your own writing, and it becomes a note you can edit, study, revise and ask questions of. The free tool stops where that work starts.

  • A structured note, not a wall of text

    Headings, hierarchy, and the details that matter — editable the moment it lands, and searchable forever after.

  • A diagram of how it connects

    Turn the note into a concept map or flowchart. The relationships prose hides become obvious.

  • Flashcards that test your material

    Generated from your own note, so revision starts from something you've already processed.

Start for free

Free plan: 1,000 AI credits a month, 5 diagrams, 5 flashcard decks. No credit card.

Frequently asked questions

How do I summarize a YouTube video?

Copy the video's link from the address bar or the Share button, paste it above and press Summarize. A minute or two later you get a summary with key points, plus the full transcript, on a page you can share.

How do I get the transcript of a YouTube video?

Paste the link above. The result page includes the video's complete transcript next to the summary, taken from its captions, so you can read or search it without playing the video.

Can I get the summary in another language?

Yes. Pick a language under the link and the summary is written in it. There are 12 to choose from, including Spanish, French, German, Portuguese, Japanese and Chinese. The transcript stays in the language the video was spoken in.

How long does it take?

Usually under two minutes. If someone has already summarized the same video, you go straight to the result.

Is it really free? Do I need to sign up?

Yes, it's free, and no. Paste a link and you get the summary without an account, an email address or a credit card.

Which videos does it work with?

Any public YouTube video that has captions, either the creator's own or YouTube's auto-generated ones. Private, members-only and age-restricted videos can't be read, and a video with no captions at all has nothing to work from.

What is LunaNotes?

LunaNotes is an AI note-taking app. You bring a video, PDF, audio file, meeting or your own writing, and it gives you an editable note plus diagrams, flashcards and an AI chat built from it. This tool runs one step of that on its own. The free plan includes 1,000 AI credits a month, with no credit card.

Can I edit the summary?

The page here is a fixed public result. To edit it, open the same video in a free LunaNotes account. The summary arrives as a note you can rewrite and turn into a diagram or flashcards.
