Extract flashcards from your own PDFs, slides and notes
Upload a lecture PDF, a slide deck, typed notes or a photo of a textbook page. DeckOwl reads the text and builds flashcards you can review with spaced repetition.
Why build your own deck instead of hunting for one
Students who want a quizlet flashcard extractor usually have course material in slide decks and lecture PDFs, not in a ready-made set that matches their syllabus. DeckOwl builds flashcards from the files you upload, so the cards reflect your professor's wording and your reading list.
- Works from PDF, DOCX, PPTX, plain text and photos of pages
- Creates flashcards with spaced repetition scheduling
- Free plan includes 3 generations per month and browser study
- Plus adds unlimited generations and PDF, DOCX, Anki and CSV export
Reads the files you already have
PDF, DOCX, PPTX, plain text and images are all supported. Photos of pages go through text recognition, so handwritten-free printed pages work too.
Spaced repetition built in
Cards resurface at the intervals that help you retain them, so you spend less time rereading and more time recalling.
Export when you need it
Plus adds PDF, DOCX, Anki and CSV export, so your cards can move into the tools you already use.
How it works
Upload your material
Drop in a PDF, slide deck, DOCX file, pasted notes or a photo of a page.
Review the generated cards
Check the flashcards DeckOwl created, edit anything that looks off, and remove cards you do not need.
Study on a schedule
Work through the deck in the browser, and let spaced repetition decide when each card comes back.
Start with the sections your exam will cover. Upload one chapter or one lecture at a time, then check that each card has a single fact on the front and a short, accurate answer on the back. Smaller batches make it easier to catch errors before they stick.
Once the deck is ready, study it in short sessions. Spaced repetition handles the scheduling, so the cards you miss come back sooner and the ones you know fade into longer intervals.

Frequently asked questions
How many flashcards should I make for a biology unit?
Most units work well with 20 to 40 cards covering key terms, processes and definitions. You can remove or add cards after reviewing the generated set.
What makes a good flashcard for studying?
Each card should test one fact, with a clear question on the front and a short answer on the back. Cards that ask how or why usually build understanding better than single words.
Can I export my flashcards?
Yes, on the Plus plan, which is $39/year or $7.99/month, with PDF, DOCX, Anki and CSV export. The free plan lets you study in the browser without exports.
Do I need a credit card to start?
No. You can start on the free plan with 3 generations per month and no credit card.
