Create flashcards from any PDF in a few minutes
Upload a PDF, slides, notes or a photo of a page. DeckOwl reads the text and drafts flashcards you can review with spaced repetition.
Turning a PDF into flashcards, step by step
Knowing how to create flashcards from PDF files saves hours when a textbook chapter runs to forty pages. Instead of copying terms by hand, you upload the file and let the tool find the definitions, dates and causes that are worth memorizing.
- Upload PDFs, slides, notes or photos of pages and get flashcards from the text.
- Edit or remove any draft card before you begin studying.
- Study in the browser on the free plan, with three generations per month.
- Plus adds unlimited generations and PDF, DOCX, Anki and CSV export.
Works with your own files
Upload PDFs, DOCX, PPTX, plain text notes or images of printed pages. Your course material becomes the source for every card.
Spaced repetition built in
Cards come back at the intervals that help you remember them, so you spend less time rereading and more time recalling.
Quizzes and mind maps too
Turn the same upload into multiple choice, true/false or short answer questions with explanations, or into a mind map of the topic.
How it works
Upload your PDF
Drag in the file from your class or textbook. No credit card is needed to start.
Review the draft cards
Check the generated questions and answers, then edit or delete any that miss the point.
Study on a schedule
Review in the browser each day. Plus users can export the set to Anki, PDF, DOCX or CSV.
Good cards ask one question each. A chapter on weather systems might produce a card asking what separates weather from climate, and another asking why albedo matters for polar ice. Read the draft set before you start, because the AI works best when you remove weak cards and keep the ones that match your course.
Once the cards are saved, spaced repetition handles the schedule. Cards you miss return sooner, and cards you know drift further out, so each study session stays focused on what you are most likely to forget.

Frequently asked questions
How many flashcards should I make from one PDF chapter?
Aim for one idea per card rather than a fixed count. A dense chapter often produces several dozen cards, and you can trim the ones that repeat the same point.
What is the best way to memorize climate terms like albedo and feedback loops?
Write each term in your own words, then test yourself without looking at the answer. Adding one real example, such as melting ice lowering albedo, makes the definition easier to recall later.
Can I export my PDF flashcards to Anki?
Yes, Anki export is included on the Plus plan at $99.90 per year or $9.99 per month. The free plan lets you study the cards in the browser but does not include exports.
Does it work with photos of printed pages?
Yes, images of pages are read with text recognition, so you can upload a photo of a printed handout as well as a PDF.
