Making a quiz from a YouTube lecture

Long YouTube lectures are easy to watch and hard to remember. If you want an AI quiz maker for YouTube videos, the practical route is to bring the lesson's text to DeckOwl: paste a transcript or your typed notes, or upload slides and PDFs. The tool reads that material and writes multiple-choice, true/false or short-answer questions with explanations.

  • Paste the transcript, not just the video link, since DeckOwl works from text you provide.
  • Clean up auto-captions for names and technical terms before generating.
  • Add slides or handouts from the same lecture to cover diagrams and formulas.
  • Retake only the questions you missed a few days later to strengthen recall.
Example photosynthesis quiz questions
Which organelle is the site of photosynthesis in plant cells?The chloroplast. It contains chlorophyll, which absorbs light energy for the process.
True or false: Photosynthesis releases oxygen when water molecules are split.True. Water is split during the light-dependent reactions, and the oxygen is released as a byproduct.
What are the reactants in the overall photosynthesis equation?Carbon dioxide and water, using light energy. Plants produce glucose and oxygen from these.
Where are ATP and NADPH produced during photosynthesis?In the light-dependent reactions on the thylakoid membranes. The Calvin cycle then uses these energy carriers.
Which enzyme fixes carbon dioxide in the Calvin cycle?RuBisCO. It attaches CO2 to RuBP, which starts carbon fixation.

Multiple-choice, true/false, short answer

Each question comes with an explanation so you learn why the right answer is right, not just which letter to pick.

Works from text you provide

Paste a transcript or typed notes, or upload PDF, DOCX or PPTX files. Photos of pages are read with text recognition.

Export when you need it

Save quizzes as PDF or DOCX, or move them into Anki or Moodle with the paid plans.

How it works

Get the transcript or notes

Copy the captions or transcript from the video, or type your own summary of the key points.

Paste or upload

Add the text to DeckOwl, or upload the lecture slides or handout as a PDF, DOCX or PPTX file.

Answer and review

Take the generated quiz, read the explanations for anything you missed, and retake the weak questions later.

DeckOwl does not fetch the video itself, so the quiz is only as accurate as the text you give it. Check the transcript for errors before you generate, and add your own notes on any point the speaker covered quickly or skipped.

Frequently asked questions

Can DeckOwl make a quiz directly from a YouTube link?

No. Paste the transcript or your own notes as text, or upload a PDF, DOCX, PPTX file or a photo of your notes. The quiz is built from the material you provide.

How many questions should I make from one photosynthesis video?

Aim for 10 to 15 questions that cover the light-dependent reactions, the Calvin cycle, and the inputs and outputs. Fewer questions often leave one stage untested.

How do I study photosynthesis with quizzes?

Answer each question before reading the explanation, then review the ones you got wrong. Spacing the same questions across several days works better than one long session.

Can I export the quiz to Moodle or PDF?

PDF and DOCX export are part of the Plus plan at $39/year or $7.99/month. QTI 2.1 and Moodle XML export are part of Pro at $14.99/month, and the free plan gives 3 generations per month with study in the browser only.
