How PDF to flashcards works
A 40-page chapter can become a deck of flashcards from PDF in a few minutes, so you spend your time studying instead of copying key terms by hand. DeckOwl reads the text, picks out terms and concepts, and writes a question on the front with the answer on the back.
- Works with PDF, DOCX, PPTX, plain text notes and images of pages.
- Generates question-and-answer cards you can review in the browser.
- Schedules reviews with spaced repetition so weak cards come back first.
- Lets Plus users export to Anki or CSV once the cards are ready.
Flashcards from any PDF
Upload PDFs, DOCX, PPTX, plain notes or photos of pages and get question-and-answer cards.
Spaced repetition built in
Cards you are about to forget come back first, so you are not reviewing the whole deck every time.
Quizzes and mind maps too
Multiple choice, true/false and short answer quizzes with explanations, plus mind maps from the same file.
How it works
Upload your PDF
Add a chapter, lecture deck or set of notes. Scanned pages are read with text recognition.
Review the generated cards
Check the front and back of each card against your source and edit anything that looks off.
Study with spaced repetition
Review cards in the browser on a schedule that adjusts to what you remember.
Cards use spaced repetition, so the ones you miss return sooner and the ones you know appear less often. If your file is a scan, photos of pages are read with text recognition, and DOCX, PPTX and plain notes work the same way.

Frequently asked questions
How many flashcards should I make from one textbook chapter?
Focus on key terms, definitions and cause-and-effect points rather than every sentence. Cut cards you already know well so your reviews stay short and useful.
How often should I review flashcards to remember them?
Review each card when it is due instead of cramming the whole deck the night before. Spaced repetition schedules this for you, so cards you miss return sooner.
Can I turn a scanned PDF into flashcards?
Yes. Scanned pages and photos are read with text recognition, so the text needs to be legible. Check the generated cards against the page for any misread words.
Do I need to pay to export my flashcards?
The free plan lets you study in the browser with 3 generations per month but no exports. Plus, at $39/year or $7.99/month, adds unlimited generations and PDF, DOCX, Anki and CSV export.
