How student quizzes work in DeckOwl

Quizzes for students are most useful when they come from the material being studied that week. DeckOwl reads uploaded PDFs, DOCX and PPTX files, plain-text notes, or photos of pages, then writes multiple-choice, true/false or short-answer questions with an explanation for each answer. The quiz runs in the browser, and the explanation shows why the right answer is right.

Questions come from your own notes, slides or readings
Multiple-choice, true/false and short-answer formats
Explanations show the reasoning behind each correct answer

Example biology cell structure quiz questions

Which organelle produces most of a cell's ATP?Mitochondria. They carry out cellular respiration, which releases energy stored in glucose and converts it to ATP.

True or false: plant cell walls are made mainly of cellulose.True. Cellulose gives the wall rigid support and keeps the cell from bursting when it takes in water.

What is the main job of ribosomes?Protein synthesis. They read messenger RNA and link amino acids into polypeptide chains.

Why does an animal cell swell and burst when placed in pure water?Osmosis. Water moves into the cell because its solute concentration is higher than the surrounding water, and an animal cell has no wall to resist the swelling.

Which structure controls what enters and leaves the cell?The cell membrane. Its phospholipid bilayer is selectively permeable, letting some molecules pass while blocking others.

Multiple-choice, true/false and short-answer questions, all built from the material you upload.

How it works

Upload the material

Add a PDF, slide deck, Word file, notes or a photo of a textbook page.

Generate the quiz

DeckOwl writes questions and explanations from the text it reads.

Study in the browser

Students work through the quiz alone and review the explanations after each answer.

These are self-paced practice quizzes for one student working alone, not live sessions where a whole class joins a shared code. Teachers or tutors who want a quiz outside the app can export it on paid plans: PDF and DOCX on Plus, and QTI 2.1 or Moodle XML on Pro. Free-plan students study in the browser only.

Frequently asked questions

How many questions should a student quiz have for one chapter?

Ten to twenty questions usually cover the main terms and ideas in a chapter without turning review into a chore. Shorter quizzes are easier to repeat, which helps more than one long attempt.

How should students use practice quizzes before an exam?

Answer from memory first, then read the explanation for every miss before checking notes. Spread quiz sessions across several days, since repeated short reviews tend to stick better than one long cram.

Can students export their quizzes?

Exports are a paid feature. Plus includes PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML, while the free plan lets students study in the browser only.

Is there a free plan, and do I need a credit card?

Yes, the free plan includes 3 generations a month and no credit card is needed to start. Students with a school email get 40% off paid plans.
