Turn your lecture PDF into flashcards in minutes
Upload a PDF, slides, notes or a photo of a page. DeckOwl reads the text and builds flashcards you can review with spaced repetition.
Why students turn a PDF into flashcards
Lecture slides and textbook chapters often hold far more terms than anyone can memorize in one pass. Turning a PDF into flashcards lets you pull the key definitions out of your own reading and drill them until they stick.
- Works with PDF, DOCX, PPTX, plain text, and images of pages
- Front shows the term or question, back shows the answer
- Export to Anki or CSV with a paid plan
- Free plan includes 3 generations per month
Reads your own files
Upload PDF, DOCX, PPTX, plain text notes, or photos of pages. Photos are read with text recognition.
Spaced repetition
Cards come back at intervals that suit how you remember, so your study time goes to the facts you miss.
Study in the browser
Start on the free plan with 3 generations a month. No credit card is needed to begin.
How it works
Upload your PDF
Drop in a PDF, slides, notes, or images of pages from your course.
Review the cards
Check the generated fronts and backs and edit any card that looks off.
Study on a schedule
Work through the deck and let spaced repetition decide which cards come back next.
Starting from your own material is faster than writing cards by hand. Upload the file, skim the cards the tool writes, and fix any question that misses the point. Cards built from your course readings tend to use the same terms your course uses, which a generic deck often does not.

Frequently asked questions
How many flashcards should I make from one chapter?
Aim for one card per distinct fact, such as a definition, a mechanism, or a cause and effect. A dense chapter may yield dozens of cards, so review the set and remove any that repeat each other.
What is the best way to study flashcards on the immune system?
Start with the two branches, innate and adaptive, then move to cell types such as neutrophils, B cells, and T cells. Say what each cell does out loud before you flip the card.
Can I export the flashcards to Anki?
Yes, but export is a paid feature. Plus includes PDF, DOCX, Anki and CSV export, while the free plan lets you study in the browser without exports.
Do I need a credit card to try it?
No. You can start on the free plan with 3 generations per month and no credit card.
