How the free version works

If you have a stack of lecture slides and no time to write practice questions, a free quiz maker can do the first draft. DeckOwl reads your own material and writes questions that match it, so you are testing what your course actually covered.

  • Multiple choice, true/false and short-answer questions
  • Explanations on every question
  • Free plan: 3 generations per month, studied in the browser
  • Plus adds unlimited generations and PDF, DOCX, Anki and CSV export

Frequently asked questions

How many questions should I make from one chapter of biology notes?

Start with 10 to 15 questions per chapter so you can finish a review in one sitting. Mix multiple choice with true/false so you test both recall and understanding.

What is the best way to study quiz questions before an exam?

Answer each question before reading the explanation, then retry the ones you missed. Spacing those retries over several days works better than cramming them once.

Can I export my quiz from the free version?

No. The free plan lets you study in the browser but does not include exports. PDF, DOCX, Anki and CSV export come with Plus, and QTI 2.1 and Moodle XML export come with Pro.

How many generations do I get for free?

The free plan includes 3 generations per month, and no credit card is needed to start. Plus gives unlimited generations, and students get 40% off with a school email.
