Why build your own math deck instead of downloading one

Ready-made math decks are easy to find, but they rarely match the notation, examples and order your instructor used. A Anki math deck built from your own course material fits the exam you are preparing for.

  • Upload handwritten notes as photos and the text is read with recognition.
  • Keep one formula or method per card so the answer is easy to check.
  • Edit any generated card before it goes into your review schedule.
  • Plus exports the deck to Anki, Moodle XML and other formats for your class.
Example math deck cards for Anki
Quadratic formula: solve ax² + bx + c = 0x = (−b ± √(b² − 4ac)) / 2a, valid when a ≠ 0.
Pythagorean theorema² + b² = c², where c is the hypotenuse of a right triangle.
Power rule: derivative of xⁿn·xⁿ⁻¹, for any real number n.
Product rule for the derivative of f(x)g(x)f′g + fg′, because both factors can change at the same time.
Addition rule for mutually exclusive events A and BP(A or B) = P(A) + P(B), since they cannot both happen.

Built from your material

Upload your lecture PDF, slides, typed notes or photos of textbook pages. The flashcards cover the theorems, definitions and worked steps in your course.

Spaced repetition

Cards you miss come back sooner and cards you know are spaced further apart, so formulas stay in memory through the term.

Export to Anki

Plus exports your math deck to Anki as a file you can import, along with PDF, DOCX and CSV. The free plan studies in the browser.

How it works

Upload your math material

Add a PDF, DOCX, PPTX, text file or image of your notes. Photos are read with text recognition.

Generate and review the cards

DeckOwl creates flashcards from your content. Edit or delete any card before you start studying.

Study or export

Study with spaced repetition in the browser, or upgrade to Plus and export the deck to Anki.

Good math cards ask for one step or one result at a time. Put the rule on the front, such as a derivative or a identity, and the reasoning or final form on the back. Keep cards short enough to answer in a few seconds, and split long proofs into several cards.

DeckOwl reads your uploaded notes and writes cards from them, so you can review and fix any wording before studying. Each new topic can become its own set of cards that you add to the same deck.

Frequently asked questions

How many cards should a math deck have per topic?

Most topics work well with 10 to 25 cards that cover each rule, its conditions and one or two worked examples. Add more cards for the steps you keep missing.

What is the best way to study math flashcards?

Say the method out loud before you flip the card, then write the steps on paper to check them. Review cards you miss more often than cards you already know.

Can I export a math deck to Anki for free?

Export to Anki is a Plus feature. The free plan lets you generate 3 times per month and study in the browser without exports.

Do I need a credit card to try it?

No. You can start on the free plan without a credit card. Students with a school email get 40% off Plus.
