Study math flashcards made from your own textbook pages
Upload a PDF, slides, notes or a photo of a page. DeckOwl turns the formulas, definitions and worked steps into flashcards you review on a spaced repetition schedule.
Why build math flashcards from your own material
Ready-made math sets often skip the exact notation, methods and examples your instructor uses, so math flashcards built from your own worked problems and lecture slides tend to be more useful. Upload a PDF, DOCX, PPTX, text file or a photo of a page, and DeckOwl writes question-and-answer cards you can review in the browser.
- Turn a chapter's formulas and theorems into cards in one upload.
- Keep cards aligned with your course notation and examples.
- Review short sessions on a schedule instead of cramming before a test.
- Switch to quizzes when you want to check whether you can apply a method.
Built from your material
Cards come from the pages you already use in class, so the terms and problem types match your syllabus.
Spaced repetition
Cards you miss return sooner, and the ones you know well wait longer, so review time goes where it helps.
Quizzes and mind maps too
Turn the same material into multiple choice, true/false or short answer quizzes with explanations, or a mind map of how the topics connect.
How it works
Upload your material
Add a PDF, DOCX, PPTX, plain text notes or a photo of a page. Text in images is read with text recognition.
Review the cards
Study in the browser on the free plan. Each card is scheduled with spaced repetition as you grade your recall.
Export when you need to
Plus adds unlimited generations and PDF, DOCX, Anki and CSV export, so you can print a set or move it into another app.
Spaced repetition schedules each card so harder formulas come back sooner than the ones you already know. Start with the definitions and theorems from your last unit, then add the procedures you keep missing on practice sets.

Frequently asked questions
How many math flashcards should I make for one exam?
Start with the definitions, formulas and theorems that appear on your study guide, which is often 30 to 60 cards for a single unit. Add procedure cards for the problem types you keep missing on practice sets.
What is the best way to study math flashcards?
Try to solve or state the answer before you flip the card, then grade yourself honestly. Keep sessions short and review often, because spaced repetition works best with frequent, regular practice.
Can I export my math flashcards to Anki?
Yes, but Anki export is a paid feature included in Plus, which costs $39 per year or $7.99 per month. Studying in the browser is included in the free plan.

No. You can start on the free plan with 3 generations per month and study in the browser without adding a credit card. Students with a school email get 40 percent off paid plans.
