Turn your own number lessons into flashcards with AI
Ready-made sets are hard to find nearby and rarely match your course. Upload a PDF, slides, notes or a photo of a page and get flashcards built from your material.
Why build your own set instead of buying one nearby
Practice sets for number flashcards are hard to find in a local store, and a generic set rarely matches the formulas, units or notation your teacher uses. Printable sheets can help with basic counting, but they cannot reflect your own course.
- Cards come from the exact pages or slides you upload.
- Spaced repetition schedules reviews around the cards you miss.
- Free plan includes 3 generations per month and browser study.
- Paid plans add PDF, DOCX, Anki and CSV export.
Built from your material
Upload a PDF, DOCX, PPTX, plain text notes or a photo of a page, and the flashcards follow what your class actually covers.
Spaced repetition
Cards you miss come back sooner and cards you know are spaced further apart, so review time goes to the numbers you still need.
Study anywhere
Study in the browser on the free plan. Paid plans add PDF, DOCX, Anki and CSV export so you can print or move your cards.
How it works
Upload your source
Add the PDF, slides, notes or photo that contains the number facts you need to learn.
Generate your cards
DeckOwl reads the text and writes flashcards with a front and a back for each key fact.
Review and export
Study with spaced repetition in the browser, or export to PDF or Anki on a paid plan.
Generating cards from your own material keeps the set aligned with your class. Upload the chapter or lecture slides, review the cards that come out, and keep the ones that cover what your exam will ask.

Frequently asked questions
How many number flashcards should I make for a math unit?
Start with the facts your unit actually tests rather than every number on the page. Add cards as you find gaps in your review sessions.
Which number facts do students usually need to memorize?
Multiplication facts up to 12 × 12, perfect squares and common powers of 2 come up often in early algebra. Your teacher's syllabus is the best guide for which facts to prioritize.
Can I export number flashcards to Anki?
Yes, on the Plus plan at $39/year or $7.99/month you can export to Anki, PDF, DOCX and CSV. The free plan includes study in the browser but no exports.
Is there a free plan?
