Or try one of these example videos:
Free: one video and one deck per day. Needs a video with captions — works best up to about 20 minutes.
Any Video Into Flashcards
Paste a link and get a ready-to-study deck drawn from the video's transcript. The video needs captions, and it works best up to about 20 minutes.
Runs On Your Device
The cards are written by Chrome's built-in AI, which runs on your own computer. The transcript stays with you — nothing is sent to a server to be turned into cards.
Edit Before You Save
Every card is a draft. Reword a question, fix an answer, or drop a card you don't need — then keep the deck.
Study With Spaced Repetition
Turn the deck into a learning session that schedules each card for review at the right time, so what you watched actually sticks.
Free, No Signup
Generate a deck without creating an account — one video and one deck per day. Sign up only when you want your decks and progress saved and synced.
Made for Lectures & Talks
Great for recorded lectures, conference talks, tutorials and course videos — anything you watched once and want to remember.
How It Works
- 1
Paste the YouTube Link
Copy the video URL and paste it above. A normal watch link, a youtu.be short link or a Shorts link all work.
- 2
We Pull the Transcript
The video opens in a reader with its transcript beside the player — readable, highlightable text instead of 40 minutes of talking.
- 3
Cards Are Written for You
On-device AI turns the transcript into question-and-answer flashcards. You watch them appear and choose how many to make.
- 4
Learn It
Save the deck and start a spaced-repetition session, so the scheduler brings each card back right before you'd forget it.
Frequently Asked Questions
How does this work?
We load the video's transcript, open it in a clean reader next to the player, and hand the text to Chrome's built-in AI, which drafts question-and-answer flashcards from it. You review the cards and save the ones you like as a deck.
How long a video can I use?
Best results up to about 20 minutes. The on-device AI reads roughly the first 20 minutes of a longer video and tells you in the generator when it did. For a long lecture, highlight the parts you care about in the reader and generate again — your highlights are always used first.
Why does it say the transcript is unavailable?
The cards come from the video's captions, so a video with captions disabled — or none yet in your language — has nothing for the AI to read. You'll still see the player, but no cards can be drafted. Try another video.
How many videos can I do per day?
One video and one deck per day on the free plan. Fetching transcripts costs us money, so the free limit is honest and small — an Ultimate plan lifts it.
Is it really free?
Yes. You can generate a deck without creating an account. Create a free account only when you want your decks and learning progress saved and synced across your devices.
Can I edit the flashcards?
Every card is a draft you can change. Reword a question, correct an answer, uncheck cards you don't want, and set how many the AI generates before you save the deck.
Is my data private?
The flashcards are written by Chrome's built-in AI, which runs on your own computer. The transcript is used on your device to make the cards and is not sent to our servers to be turned into flashcards.
Why don't I see any flashcards generated?
The generator uses Chrome's built-in AI, which needs Chrome 138+. If nothing appears, update your browser or check our troubleshooting guide. If the video simply has no captions, there's nothing to make cards from.
What happens when I use the AI for the first time?
Chrome downloads its on-device AI model the first time — about 3–4 GB. This can take several minutes depending on your connection — keep the tab open. You'll see a download percentage while it runs.
How do I study the deck afterwards?
Once the deck is saved you can start a learning session. Cards are scheduled with spaced repetition, so you review each one right before you'd forget it — the most efficient way to memorize.
What if the AI model won't download or work?
Make sure you have about 22 GB of free disk space — that's Chrome's threshold before it downloads the model, not the model's size (it's about 3–4 GB) — and try enabling the Chrome AI flags in chrome://flags/.
