What Flashcards and quizzes gives you

  • Made for you, instantly

    No typing out cards. The quiz and flashcards are generated from the content of the summary.

  • Multiple-choice quiz

    Answer questions on the material and see your score.

  • Flip-to-reveal flashcards

    A question on one side, the answer on the other. Try to recall it before you flip.

  • From any source

    Lectures, tutorials, articles and papers: if SumAI can summarize it, it can quiz you on it.

Reading is not the same as knowing

You finish a lecture summary and it all makes sense. A week later you can recall the title and not much else. That gap between recognizing something and being able to retrieve it is the oldest problem in studying.

The fix is well established: test yourself. Pulling an answer out of memory strengthens it in a way that rereading does not. SumAI builds that step in, by giving you a quiz and flashcards with every summary.

What the research says

Two findings are worth knowing, stated as carefully as the studies state them.

A 2013 review by Dunlosky and colleagues assessed ten common learning techniques. Only two were rated high utility: practice testing and distributed practice (spreading study over time). Rereading and highlighting were rated low.

A 2006 experiment by Roediger and Karpicke compared students who restudied a passage with students who took recall tests on it. Five minutes later, the restudy group did slightly better. Two days and one week later, the tested group remembered substantially more. Testing pays off on the timescale that matters for exams.

That last detail explains why testing feels less effective than it is. Rereading gives you the comfortable feeling of fluency today. Testing gives you the memory next week.

A routine that uses both tools

  1. Read the summary once. The Study Guide style suits this.
  2. Quiz yourself immediately. Treat wrong answers as a list of what to look at again.
  3. Check the points you missed, using the timestamps or Ask AI.
  4. Return to the flashcards a day or two later, and again after a week. Spacing the reviews is the second high-utility technique.

Fifteen minutes spread over three days does more than an hour in one sitting.

Getting more from flashcards

  • Answer before you flip. Say or think the answer first. Flipping straight away turns a test into rereading.
  • Explain, do not just recall. After a card, ask yourself why the answer is true.
  • Use the map. The mind map shows where each card sits in the bigger picture.

An honest note

Generated questions are a fast way to start testing yourself, and they are only as good as the summary they come from. If a question looks wrong, check it against the source. For high-stakes exams, use the quiz to find your gaps and your course materials to fill them.

Step by step

How to turn a YouTube video into flashcards on iPhone

  1. Summarize the video

    Paste the YouTube link into SumAI or share the video from the YouTube app. For study material, the Study Guide style works well.

  2. Read the summary once

    Go through the key points so the questions have something to test.

  3. Take the quiz

    Open the quiz and answer the questions. Your score shows what to revisit.

  4. Review with flashcards

    Go through the flashcards, answering each one in your head before you flip it. Come back to them a day or two later.

FAQ

Questions about flashcards and quizzes

Can AI turn a YouTube video into flashcards?

Yes. SumAI generates flashcards and a quiz from every summary, including summaries of YouTube videos. Summarize the video, then open the flashcards or the quiz for that summary.

Can I make flashcards from a PDF?

Yes. SumAI creates a quiz and flashcards from summaries of PDFs with selectable text, as well as from videos and web articles.

Are quizzes better than rereading?

For remembering later, yes. A widely cited 2013 review by Dunlosky and colleagues rated practice testing as a high-utility learning technique and rereading as low utility. In a 2006 study by Roediger and Karpicke, students who tested themselves remembered more after two days and after a week than students who restudied.

Do I have to create the questions myself?

No. SumAI writes the quiz questions and flashcards from the content of the summary automatically.

Does the quiz show a score?

Yes. The quiz is multiple choice and shows your score, so you can see how much of the material you have retained.
