How to convert a YouTube video into a quiz
Whether you're cramming for an exam from a Khan Academy lecture or testing yourself on a Crash Course episode, here's how to turn any YouTube video into a comprehensive quiz in under a minute.
Step-by-step
- 1Find a YouTube video with captions. Auto-generated captions work, but manually-added captions give the most accurate results.
- 2Copy the video URL — full link or short youtu.be/ form, both are accepted.
- 3Paste it into the input above and choose how many questions you want and which question types (multiple-choice, true/false, short answer).
- 4Wait around 30 seconds while the AI extracts the transcript and generates an explanation for every answer.
Tips for the best quiz
- Pick lecture videos (10+ minutes) over Shorts — more transcript means richer questions.
- Manually-captioned videos beat auto-generated ones for technical material with jargon.
- If a video is very long (90+ minutes), chunk it: jump to the chapter you're studying and use that segment's URL.
- Pair the quiz with your own notes — re-take the quiz after a review session for spaced retention.
When this works best
- Reviewing a recorded lecture before an exam
- Self-testing after watching a MOOC, Crash Course, Khan Academy, or MIT OpenCourseWare video
- Language learning — generate questions from a captioned video in the language you're studying

YouTube to Quiz FAQ
StudyGlen extracts the captions (subtitles) from the YouTube video, then uses AI to analyze the content and generate relevant quiz questions with explanations.
Yes, the video needs captions (subtitles) — either auto-generated by YouTube or manually added by the creator. Most YouTube videos have auto-generated captions.
If the video has neither manual nor auto-generated captions, the AI cannot extract content and the quiz cannot be generated. Most YouTube videos uploaded after 2010 have auto-generated captions enabled by default — try a different video, or paste the transcript manually if you already have one.
Yes! Guest users can generate 1 quiz per day without creating an account. Free registered users also get 1 quiz per day.
YouTube to quiz works with videos in any language that has captions. The AI auto-detects the language and generates questions accordingly.
There's no strict length limit, but longer videos with more caption content produce better quizzes. Very short videos (under 2 minutes) may not have enough content for quality questions.
Yes, but Shorts (under 60 seconds) usually contain too little content for a meaningful quiz — you'll typically get only 2–3 questions. For better results, use full-length lecture videos or tutorials.
Unlisted videos work as long as the link is accessible without sign-in. Private videos (visible only to specific accounts) cannot be processed because the caption extractor needs public read access. If you control the video, switch it to Unlisted before pasting the URL.
Currently one video at a time per quiz. If you want to combine sources — for example, a full course playlist — generate one quiz per video; they all live in your library and can be retaken in any order.
Auto-generated captions are typically 90–95% accurate for clearly-spoken English. Heavy accents, background music, technical jargon, or non-English videos with auto-captions can drop accuracy. The AI is robust to small caption errors — it understands context — but for high-stakes study material we recommend videos with manually-uploaded captions when possible.
We store the video URL alongside your generated quiz so you can re-open it later — nothing else from the video is retained. We don't download or rehost the video itself. Generated study content from public videos is for personal study; respect creators' rights and don't redistribute the AI output as your own teaching material without attribution.
Yes — multiple-choice is the default question type. You can also choose true/false or short-answer, or mix all three. The AI generates four plausible options per multiple-choice question with one correct answer plus an explanation.
