How a PDF becomes a quiz
Students who want a free PDF to quiz workflow usually need two things: a tool that costs nothing to try, and enough generations to cover a full term of readings. DeckOwl's free plan includes 3 generations a month and studying in the browser, so you can check the question quality on your own material before paying anything.
- Free plan: 3 generations per month, studied in the browser
- Plus at $39/year or $7.99/month: unlimited generations and PDF, DOCX, Anki and CSV export
- Pro at $14.99/month adds a stronger AI model, bulk upload, QTI 2.1 and Moodle XML export
- Students get 40% off with a school email, and no credit card is needed to start
Upload your own PDF
Drop in a lecture PDF, a slide deck, or a photo of a textbook page. Text recognition reads images too.
Three question types
Multiple choice, true/false and short answer questions, each with an explanation so wrong answers still teach you something.
Study in the browser
The free plan lets you take quizzes online. Plus adds PDF, DOCX, Anki and CSV exports for your other tools.
How it works
Upload the PDF
Add a PDF, DOCX, PPTX, text file or image of your notes.
Choose a question type
Pick multiple choice, true/false or short answer for your quiz.
Take the quiz
Answer each question, read the explanation, and retry the ones you missed.
A quiz built from your own lecture notes tests what your professor actually covered, which a generic question bank may not. If you need more than three generations in a month, Plus at $39/year or $7.99/month removes the cap.

Frequently asked questions
How many questions should a practice quiz have for a biology chapter?
Around 10 to 20 questions works well for one chapter, mixing recall questions with a few application questions. Retake the quiz after a day or two to check what you retained.
Is multiple choice or short answer better for studying biology?
Multiple choice is quick for checking vocabulary and definitions, while short answer forces you to explain processes like respiration in your own words. Using both gives a fuller picture of what you know.
Is the free plan really unlimited?
No. The free plan includes 3 generations per month and browser study. Unlimited generations start on Plus at $39/year or $7.99/month.
Can I export a quiz to Moodle or QTI?
Yes, but only on Pro at $14.99/month, which includes QTI 2.1 and Moodle XML export. PDF, DOCX, Anki and CSV export are available on Plus.
