Create flashcards using your PDF notes in minutes
Upload a PDF, slides, a document or a photo of a page. DeckOwl reads the text and builds flashcards you can study with spaced repetition.
Why turn a PDF into flashcards
Many students end up with a long PDF of lecture notes and no time to rewrite them by hand, so being able to create flashcards using PDF material directly saves hours each week.
- Upload a PDF, slides, DOCX, notes or a photo of a page
- Keep each card to one fact so it is easier to recall
- Review on a spaced schedule instead of cramming the night before
- Export to Anki or CSV on the Plus plan if you want to study elsewhere
Works with your own files
Upload PDFs, DOCX, PPTX, plain text notes or images. Photos of pages are read with text recognition.
Spaced repetition built in
Cards come back at the right intervals so you review what you are about to forget, not what you already know.
Study in the browser
Start on the free plan with no credit card and study right away. Exports to PDF, DOCX, Anki and CSV are part of Plus.
How it works
Upload your PDF
Drag in a chapter, lecture deck or set of notes. Text is extracted automatically.
Review the generated cards
Check the flashcards DeckOwl writes from your material and keep the ones you need.
Study with spacing
Work through the deck in the browser and let spaced repetition schedule your reviews.
Good flashcards ask one specific question with one clear answer. Working from your own pages keeps the cards tied to what your instructor actually covers, not a generic set.
Because the cards come from your own file, you can make a new deck for each chapter or unit and review it on a schedule that fits your exam dates.

Frequently asked questions
How many flashcards should I make from one chapter?
Aim for one card per key term, definition, or cause-and-effect idea in the chapter. Most chapters produce a manageable deck of 20 to 60 cards, and you can trim the list after reviewing the generated set.
What makes a flashcard easier to remember?
Keep one fact per card and write the question in your own words where you can. Cards that you explain aloud before flipping them tend to stick better than ones you only read.
Is it free to create flashcards from a PDF?
The free plan includes 3 generations per month and lets you study in the browser. Unlimited generations and spaced repetition come with Plus.
Can I export the flashcards to Anki?
Yes, Anki export is part of the Plus plan, which also includes PDF, DOCX and CSV export. The free plan is for studying in the browser only.
