  • No install: quizzes run in any modern browser.
  • Upload PDFs, slides, notes, or photographed pages.
  • Multiple choice, true/false, and short answer with explanations.
  • Free plan includes 3 generations per month, no credit card needed.

Questions from your material

Quizzes are built from your own PDF, DOCX, PPTX, text, or photographed pages, so they match what your class actually covers.

Explanations for every answer

Each question comes with a short explanation, so a wrong answer teaches you something instead of just marking you down.

Add a PDF, slide deck, Word file, plain text, or a photo of a page.

Pick multiple choice, true/false, or short answer, and set how many questions you want.

Frequently asked questions

How many quiz questions should I make from one chapter?

Most chapters work well with 15 to 25 questions, mixing multiple choice with true/false so you practice both recall and recognition. Start with the sections you find hardest and add more questions as you go.

How do I study with quiz questions effectively?

Answer each question from memory before you check, and write down why each wrong option is wrong. Retake missed questions after a day or two instead of rereading the whole chapter.

Is there a free app I can download to make quizzes?

DeckOwl runs in your browser, so there is nothing to download. The free plan includes 3 generations per month and studying in the browser, but exports require the paid Plus plan.

Can I export my quiz to Moodle or QTI?

Yes, QTI 2.1 and Moodle XML export are included in the Pro plan at $14.99 per month. The free plan does not include exports.
