How a free online quiz tool fits into your study week
Most quiz sites make you type every question yourself, which takes longer than the studying it is supposed to support. A free quiz tool online should start from the notes and slides you already have, so the practice matches the exam you are preparing for.
- Upload PDFs, slides, notes or photos of pages
- Get multiple-choice, true/false and short answer questions
- Read an explanation for every answer
- Start on the Free plan with no credit card needed
Multiple-choice, true/false and short answer
Each question comes with an explanation, so a wrong answer teaches you why the right one is correct.
Built from your material
Questions come from the pages you upload, not a generic question bank, so the quiz matches what your class covers.
Photos work too
Snap a page from a textbook or handout and text recognition reads it, so you can quiz yourself without retyping anything.
How it works
Upload your material
Add a PDF, DOCX, PPTX, plain text notes or a photo of a page.
Choose a question type
Pick multiple-choice, true/false or short answer, then generate your quiz.
Answer and review
Work through the questions in your browser and read the explanation after each one.
Quizzing yourself on a unit before the test is one of the most useful habits you can build. Short sets of questions show you which ideas have slipped, and the explanations fill the gaps while the material is still fresh.
The Free plan gives you 3 generations per month and lets you study in the browser. If you want to keep questions outside DeckOwl, PDF and DOCX export are on the Plus plan, and QTI 2.1 and Moodle XML export are on Pro.

Frequently asked questions
How many practice questions should I make for a fractions and decimals unit?
Start with 10 to 15 questions per section so you can cover equivalent fractions, adding decimals and converting between the two. Repeat the topics you miss in a second round.
What is a good way to practice converting fractions to decimals?
Work the problem by hand first, then check your answer against the explanation. True/false questions such as 'is 3/8 equal to 0.375' are good for catching common slips.
Is there a free plan?
Yes. The Free plan includes 3 generations per month and studying in the browser. Exports to PDF, DOCX, Anki and CSV are paid features on the Plus plan.
Can I export quizzes to Moodle?
Moodle XML and QTI 2.1 export are included in the Pro plan at $14.99 per month.
