Make flashcards from a YouTube video
Lectures, crash courses, language videos, certification prep — the material is on YouTube, but flashcards are how it sticks. Three ways to get from video to cards, fastest first.
Way 1: One click — the built-in self-test
- Paste the video link on VidWords and run Watch with AI.
- Switch the journey to Study notes. Watch turns the analysis into recall cards: each chapter and key point becomes a "test yourself" prompt with the answer hidden until you expand it.
- Quiz yourself right on the page — recall first, then reveal. Every card links back to the timestamp, so a shaky answer takes one click to re-watch.
Because AI Watch reads the frames as well as the audio, the cards can cover things caption-only tools never see — the diagram, the worked example on the slide, the numbers in the table.
Way 2: Export to Anki, Quizlet, or Notion
The built-in self-test is recall practice, not spaced repetition. For long-term retention you want the cards in a real SRS app — and that's an export away:
- In the Watch journey, click Download .md. You get Markdown with the TL;DR, each chapter's summary and takeaways, and key moments.
- Convert takeaways to question–answer pairs. An LLM does this in seconds — paste the Markdown with: "Turn each takeaway into a flashcard as CSV with columns question,answer. Questions test recall, answers are one sentence."
- Import: Anki — File → Import, map the two columns. Quizlet — paste the CSV rows into a new set. Notion/Obsidian — the Markdown drops in as-is; use a toggle-list template for reveal-style cards.
Way 3: DIY from the transcript (free)
No Watch minutes? The free transcript plus any LLM makes solid text-only cards. Get the transcript, switch to plain text, copy it, and use this prompt:
Below is the transcript of an educational YouTube video.
Create 15-25 flashcards from it:
- Format each as "Q: ..." / "A: ..." on separate lines.
- Questions must test understanding, not trivia.
- Answers: 1-2 sentences, faithful to the transcript.
- Cover the whole video, in order.
- Include any formulas, definitions, and numbers verbatim.
[paste transcript here]This route is free and works everywhere — its limit is that the cards only know what was said. If the payoff is on the slides (math derivations, code, anatomy diagrams), the transcript alone misses it; that's exactly the gap the Watch study view closes.
Which way should you use?
| Built-in self-test | Markdown → Anki | Transcript + LLM | |
|---|---|---|---|
| Effort | One click | ~5 minutes | ~5 minutes |
| Covers visuals (slides, diagrams) | Yes | Yes | No — speech only |
| Spaced repetition | No — on-page recall | Yes (Anki/Quizlet) | Yes, after import |
| Cost | Included Free-plan Watch minutes | Included Free-plan Watch minutes | Free |
Honest guidance: cramming tonight → built-in self-test. Studying a course over a semester → Markdown → Anki. Zero budget and the video is talk-driven → transcript + LLM.
FAQ
Can AI really make good flashcards from a video?
Yes, when the cards stay anchored to the source. Watch builds cards from its evidence-indexed analysis (with timestamps to verify); the DIY prompt above instructs the model to stay faithful to the transcript. Skim any AI-generated deck once before trusting it for an exam.
Does this work for language learning?
Yes, when the video provides a caption track in the language you need. You can turn vocabulary from that transcript into contextual cards and pair it with a separately verified translation for front/back prompts.
Can I do a whole playlist?
For transcripts, yes — bulk extraction handles up to 500 videos from a playlist or channel. Watch analyzes one video at a time; run it on the lectures that matter most.
