Frequently Asked Questions
Everything you need to know about our free YouTube transcript and summary tool
It's a free online tool that produces an accurate transcript and a structured AI summary for almost any public YouTube video. Paste a URL and you get a shareable results page a minute or two later. It's made by LunaNotes, and it runs one step of that app on its own.
LunaNotes is an AI note-taking app. You bring a source — a video, a PDF, an audio file, a meeting, or your own writing — and it produces a structured note you can edit, plus diagrams, flashcards and an AI chat built from that note. YouTube is one of the places a source can come from, not the whole product. This tool exists so you can judge the output before you sign up for anything.
The free plan gives you 2,000 AI credits a month (roughly 400 notes), 100 MB of storage for files you upload, 5 AI diagrams and 5 flashcard decks — no credit card. That's the point where a summary stops being a fixed public page and becomes a private note you own, edit and keep.
Use it as often as you like — this tool is free and we don't meter it. What an account adds isn't more runs, it's somewhere for the results to live: private notes you can edit, organise and come back to.
We use advanced AI technology to ensure high accuracy. However, the quality may vary depending on the video's audio clarity, accents, and background noise.
Not on this page — what the free tool produces is a fixed, public, shareable result. Editing is exactly what LunaNotes is for: run the same video in a free LunaNotes account and the summary arrives as a note you can rewrite, restructure, highlight and add your own thinking to, then turn into a diagram or a flashcard deck.
No. The tool works without an account and there's no credit card anywhere in the flow. An account is what you want when you'd like to keep the result, edit it, and build on it.
It works with most YouTube videos, but not all, for example, private videos, videos with paywall or videos with few views. If you have any issues, please contact us.
After generation, you'll receive a unique URL that you can easily share with others.
Yes. Pick a language in the form and the summary is written in it — we support 12+, including Spanish, French, German, Portuguese, Japanese and Chinese. Leave it on "Auto" and we follow the video's own language. The transcript itself is taken verbatim from the video's captions, so it always stays in the language the video was spoken in.
