How the PDF becomes a quiz

Review sessions run faster when the questions already exist. Instead of writing a pdf to quiz game from scratch after every lecture, upload the reading or slides and let the AI draft the questions from the same text your students were given.

  • Start from the PDF or slides your class already uses, so the questions match the lesson.
  • Mix multiple-choice, true/false and open questions to test recognition and recall.
  • Read the explanations aloud after each answer to turn mistakes into quick teaching points.
  • Keep a short set of 10 to 20 questions so the review fits a class period.
Example biology review questions for a quiz game
What organelle produces most of a cell's ATP?The mitochondrion. It carries out most of the oxidative phosphorylation that makes ATP, so it is the main energy source for the cell.
During which phase of mitosis do chromosomes line up along the cell's equator?Metaphase. Spindle fibers attach to the kinetochores and align the chromosomes along the metaphase plate.
True or false: DNA replication is semiconservative.True. Each new double helix keeps one original strand and one newly made strand, as the Meselson-Stahl experiment showed.
What is the net ATP yield from one glucose molecule in glycolysis?Two ATP. Glycolysis spends two ATP in its investment phase and produces four, so the net gain is two.
Why do enzymes lower activation energy?They stabilize the transition state, so fewer molecules need extra energy to react, which speeds up the reaction without being used up.

Works from your own files

Upload PDFs, DOCX or PPTX files, plain notes, or photos of pages. Text recognition reads the material so the questions match what your class actually covered.

Three question types

Generate multiple-choice, true/false or open questions. Each one includes an explanation, so a wrong answer becomes a short lesson instead of just a missed point.

Study or export

Practice the quiz in your browser on the free plan. Paid plans export to PDF, DOCX, Anki and CSV, and Pro adds QTI 2.1 and Moodle XML for learning management systems.

How it works

Upload your material

Add a PDF, slide deck, notes file or photo of a page. Choose the question type you want to start with.

Generate the questions

DeckOwl builds multiple-choice, true/false or open questions from the text, each with an explanation of the correct answer.

Run the review

Work through the quiz on your own or read the questions aloud for a class review. Export on a paid plan if you need a file.

Good review questions test understanding, not just memory of a sentence. Check the generated questions before you use them, remove any that do not match the lesson, and keep the explanations so students can see why each answer is right or wrong.

Frequently asked questions

How many questions should a review quiz game include?

Most review sessions work well with 10 to 20 questions, which fits a short class period. Shorter sets are easier to repeat, which helps with recall.

Do quiz questions need explanations to help students learn?

Yes. A short reason for the correct answer shows students why the other choices are wrong, not just which one scored a point.

Can I export a quiz from DeckOwl?

Exports are a paid feature. Plus includes PDF, DOCX, Anki and CSV export, and Pro adds QTI 2.1 and Moodle XML for learning management systems.

Is there a free plan?

Yes. The free plan includes 3 generations per month and studying in the browser, and no credit card is needed to start.
