Turn any PDF into flashcards you can study online
Upload a PDF, slide deck, set of notes or a photo of a page. DeckOwl reads the text and builds flashcards you can review in your browser on a spacing schedule.
Why turn a PDF into flashcards
Your lecture PDF is full of terms and dates, but rereading it rarely makes them stick. online flashcards from PDF files let you pull out the key facts and drill them on a schedule, which is closer to how memory works.
- Paste or upload the source you already have, so the cards reflect your course.
- Check each card against the original text before you rely on it.
- Review a short set every day and let spaced repetition set the timing.
- Use a quiz or mind map alongside the cards when you want to test understanding.
Built from your own PDF
Flashcards come from the material you upload, so they match your course readings and not a generic question bank.
Spaced repetition
Cards you miss come back sooner and cards you know fade into longer gaps, which keeps review time focused.
Works with more than PDFs
Upload DOCX, PPTX, plain text notes or images of pages, and the text is read with recognition before cards are made.
How it works
Upload your PDF
Drag in a PDF, or add slides, notes or a photo of a page. No credit card is needed to start.
Generate your cards
DeckOwl reads the text and drafts flashcards, which you can check and edit before studying.
Study in your browser
Review the cards online on a spaced repetition schedule and come back to the ones you find hard.
Start with one chapter or one section rather than the whole document. Shorter sets are easier to check for accuracy, and reviewing a small batch daily tends to work better than a long session once a week.

Frequently asked questions
How many flashcards should I make from one chapter?
Most chapters work well with a focused set of cards covering the main terms, dates and causes, rather than every sentence. Start small, review them, and add more only where you keep missing.
How do I study flashcards so they stick?
Review a little every day instead of cramming, and say the answer aloud or in writing before you flip the card. Mark cards you miss so they come back sooner.
Can I use my PDF on the free plan?
Yes, the free plan includes 3 generations per month and lets you study in the browser. Exports are part of the paid Plus plan.
Can I export my flashcards after I make them from a PDF?
Export is a paid feature, and Plus includes PDF, DOCX, Anki and CSV export along with unlimited generations. Plus is $39 per year or $7.99 per month, and students get 40% off with a school email.
