Turn any class PDF into flashcards for students to study
Upload lecture slides, notes, or a photo of a textbook page, and DeckOwl builds a flashcard deck you can review with spaced repetition.
Why a custom deck beats a generic printable one
Printable sets of PDF flashcards for students tend to cover a generic syllabus, while your exam covers the specific chapters your instructor assigned. Starting from your own PDF keeps the cards aligned with what you will actually be tested on.
- Cards cover your chapters, not a generic syllabus.
- Photos of printed pages are read with text recognition.
- Spaced repetition schedules reviews so well-known cards come back less often.
- The free plan includes 3 generations per month, studied in the browser.
Built from your material
Upload PDFs, DOCX, PPTX, notes, or photos of pages. Text in images is read with text recognition.
Spaced repetition
Cards return at intervals timed to when you are likely to forget them, so review time goes to what you need most.
Study in the browser
The free plan lets you study your deck in the browser. Plus adds PDF, DOCX, Anki, and CSV export.
How it works
Upload your PDF
Add a chapter, lecture deck, or set of notes from your course.
Review the cards
Edit or delete any card that does not match what your instructor covered.
Study on a schedule
Spaced repetition brings cards back as you approach the point of forgetting them.
Upload the file, review the generated cards, and delete anything that does not match your lecture. Because every card comes from your own text, you can check each answer against the source page.

Frequently asked questions
How many flashcards should I make for an intro biology chapter?
Most students do best with one card per distinct term or idea, so a dense chapter can need several dozen cards. Start with key terms and definitions, then add cards for processes that are easy to confuse.
What is the best way to study flashcards from a PDF?
Review cards in short sessions and try to recall each answer before flipping the card. Spaced repetition helps by showing the cards you miss more often.
Can I export my flashcards to a PDF?
Yes, PDF export is included with Plus at $39/year or $7.99/month. The free plan lets you study your deck in the browser without exports.
Do I need a credit card to start?
No, you can start on the free plan without a credit card. Students with a school email get 40% off Plus.
