Why build your own quiz instead of using a generic one
Pre-made free online quizzes rarely match what your teacher covered this week, which is why DeckOwl builds them from your own material instead.
- Questions match your own lessons, not a generic pool.
- Multiple-choice, true/false and short answer formats from one upload.
- Explanations for every question, whether you answered it right or wrong.
- Free plan for light use. PDF, DOCX, Anki and CSV export starts on Plus.
Built from your material
Upload a PDF, DOCX, PPTX, plain text or a photo of a page, and get questions drawn from your own lessons.
Explanations included
Every multiple-choice, true/false or short answer question comes with an explanation, so wrong answers still teach you something.
Free to start
The free plan includes 3 generations per month and studying in the browser, with no credit card needed to begin.
How it works
Add your notes
Upload a file or paste text. Photos of pages are read with text recognition.
Pick a question type
Choose multiple choice, true/false or short answer, then generate your quiz.
Study and review
Answer the quiz in your browser and read the explanations for anything you missed.
Generic question banks often test topics you have not studied yet, so you spend time on the wrong material. A quiz generated from your slides or notes focuses on the exact definitions, examples and problem types your course uses.
Because each question includes an explanation, you can check your reasoning after every answer rather than only seeing a score at the end.

Frequently asked questions
How many practice questions should I do for fractions and decimals?
Start with 10 to 15 mixed questions, then repeat the ones you missed. Spreading practice over several days works better than one long session.
What is the fastest way to check a fraction-to-decimal answer?
Divide the top number by the bottom number and compare the result to your answer. Estimating first, such as knowing 1/2 equals 0.5, catches most mistakes.
Is DeckOwl free to use?
The free plan includes 3 generations per month and studying in the browser, and you do not need a credit card to start. Exporting to PDF, DOCX or Anki requires a paid plan.
Which export formats are included in paid plans?
