How a quiz from a YouTube video actually gets made

Lecture and tutorial videos are hard to test yourself on while you watch them, so a quiz maker using a YouTube link is often what people really want. DeckOwl does not fetch a URL directly. Copy the transcript or your typed notes into a text file or DOCX, upload it, and the AI writes questions that each come with an explanation.

Paste the transcript and remove timestamps or ads that add noise.
Add your own notes for slides or diagrams the transcript does not describe.
Start with short answer questions to check recall, then switch to multiple choice.
Review every explanation, not just the questions you got wrong.

Example cell biology quiz questions from a lecture video

Which organelle produces most of a cell's ATP?Mitochondria. They carry out cellular respiration, which generates most of the ATP in aerobic cells.

True or false: plant cells lack a cell membrane.False. All cells have a plasma membrane, and plant cells also have a cell wall outside it.

What is the main function of ribosomes?Protein synthesis. They translate mRNA into polypeptide chains.

True or false: osmosis moves water from low solute concentration toward high solute concentration.True. Water moves across the membrane toward the side with more dissolved solute, which has lower water potential.

Why does the nucleus need a nuclear envelope?It separates DNA from the cytoplasm and controls what passes through the nuclear pores.
