Study math formulas with electronic flashcards made from your notes
Upload a PDF, slides, or a photo of a textbook page and get math flashcards with spaced repetition.
Why electronic math flashcards work better than retyping notes
Math rewards repetition, since formulas, identities and theorem statements only stick when you recall them on a schedule. Electronic math flashcards let you drill those items in short sessions on any device, and spaced repetition moves the hard ones back into rotation sooner.
- Start with one card per definition, theorem, and formula in the chapter.
- Add a separate card for each solution step you tend to forget on practice problems.
- Keep answers short enough to recall in a few seconds, such as the final formula.
- Review a little every day instead of cramming a full unit the night before a test.
Cards from your own material
Drop in a PDF, DOCX, PPTX, plain-text notes, or a photo of a page. DeckOwl reads the text and proposes cards from your course, not a generic deck.
Spaced repetition scheduling
Cards you miss come back sooner and cards you know drift further out, so formulas and theorem statements stay in memory between exams.
Edit before you study
Change any question or answer before a session. This helps when your course uses a different notation than the one the model chose.
How it works
Upload your material
Add the PDF, slides, notes, or image of the math chapter you are studying.
Review the generated cards
Check definitions, formulas, and worked steps, and fix any notation that does not match your class.
Study on a schedule
Work through the due cards in your browser each day. Spaced repetition sets the order and timing for you.
DeckOwl reads your lecture slides, worksheets, or photos of a textbook page and proposes cards for definitions, formulas, and the steps in worked examples. You can edit any card before studying, which matters when your instructor uses a different convention.
Free accounts can generate three sets per month and study in the browser. Paid plans add unlimited generations and export to PDF, DOCX, Anki, and CSV.

Frequently asked questions
How many flashcards should I make for a calculus unit?
Start with one card per definition, theorem, and formula in the unit, then add cards for the steps you miss on practice problems. The right total depends on how much of the material you already know.
Should a math flashcard show the full worked solution on the back?
Keep the back short enough to recall in a few seconds, such as the final formula or the first step. Put the full solution on its own card so you practice the method rather than memorizing one answer.
Can DeckOwl export math flashcards to Anki?
Yes, but export is a paid feature. The Plus plan costs $99.90 per year or $9.99 per month and includes Anki, PDF, DOCX, and CSV export, while the free plan lets you study cards in the browser.
Does DeckOwl work with photos of printed math pages?
Yes, images are read with text recognition, so photos of printed pages generally work. Handwritten math may be read less accurately, so check the generated cards before you study them.
