Turn your PDFs into flashcards you can study today
Upload a PDF, slide deck or set of notes, and DeckOwl's AI writes the flashcards for you. Then review them on a spaced repetition schedule.
Why students turn to a flashcard app from PDF
Most course readings arrive as long PDFs, and making cards by hand from every chapter takes longer than the studying itself. A flashcard app from PDF lets you skip the copying step and start reviewing the same day the reading is assigned.
- Upload a PDF, slides, notes or a photo of a page
- Review and edit cards before studying them
- Study in the browser on the free plan
- Export to Anki, CSV, PDF or DOCX on the Plus plan
Works with your files
Upload PDFs, DOCX, PPTX, plain text, notes or photos of pages. Photos are read with text recognition.
Spaced repetition built in
Cards return at the right time, so the ones you miss come back more often until they stick.
Quizzes and mind maps too
The same material can also produce multiple choice, true/false and short answer quizzes with explanations, plus mind maps.
How it works
Upload your material
Add a PDF, slide deck, document or a photo of a page.
Check the cards
Review the generated flashcards and edit any that need fixing before you study.
Study on schedule
Spaced repetition brings each card back just before you are likely to forget it.
The app reads the text in your file and proposes question and answer cards. You can check each one against the source, delete weak cards, and add your own before you begin reviewing.
Spaced repetition then decides what to show you next. Cards you know well appear less often, and cards you miss appear again soon, which keeps review time focused on the material you have not yet learned.

Frequently asked questions
How many flashcards should I make for probability basics?
Start with one card per definition or rule, which usually means 20 to 40 cards for a single chapter. Add more cards for the formulas you mix up, like the addition and multiplication rules.
How do I study probability with flashcards?
Put the rule or definition on the front and a worked example or the formula on the back. Review the cards on a schedule, and say the reasoning out loud instead of only recalling the answer.
Do I need a credit card to start?
No. The free plan gives you 3 generations per month and browser study, and you can start without entering a credit card.
Are exports included for free?
Exports are part of the paid plans. Plus includes PDF, DOCX, Anki and CSV export, and Pro adds QTI 2.1 and Moodle XML.
