Turn any PDF into flashcards with AI
Upload a PDF, slides, notes or a photo of a page. DeckOwl builds flashcards you can review with spaced repetition.
Why turn a PDF into flashcards
Lecture PDFs often run to dozens of pages, and rereading them rarely sticks. AI that turns PDFs into flashcards reads the text, pulls out terms and definitions, and builds a deck you can review in minutes. You can also start from slides, DOCX files, plain notes or a phone photo of a page.
- Reads PDF, DOCX, PPTX, plain text and photos of pages
- Cards show a question or term on the front and the answer on the back
- Spaced repetition schedules reviews around the cards you miss
- The free plan includes 3 generations a month and browser study
Reads your own files
Upload PDF, DOCX, PPTX, plain text or images. Photos of pages are read with text recognition.
Clean question and answer cards
Each card has a term or question on the front and a short, exact answer on the back, so you can check yourself quickly.
Spaced repetition built in
Cards you miss come back sooner, and cards you know are spaced further apart, so review time goes where it helps.
How it works
Upload your material
Add a PDF, slide deck, set of notes or a photo of a page from your course.
Generate the flashcards
DeckOwl reads the text and turns the key terms and ideas into a deck of flashcards.
Study and review
Work through the deck in your browser and let spaced repetition schedule what you see next.
Good cards ask for one thing each. Keep the front to a single term or question and the back to a short, exact answer, then let spaced repetition decide how often each card returns. Cards you struggle with come back more often, which is where most of the study time pays off.

Frequently asked questions
How many flashcards should I make from one chapter of cell biology?
Aim for one card per distinct term or process, which often lands between 20 and 40 for a typical chapter. If a card tests two facts at once, split it into two.
Which cell biology topics work best as flashcards?
Organelle functions, transport types, and the stages of mitosis work well because each has a short, checkable answer. Long explanations are better read in the text and then summarized on a card.
Can I export the flashcards to Anki?
Yes, Anki export is included with Plus, which costs $39 per year or $7.99 per month. The free plan lets you study in the browser without exports.
Is there a free plan?
Yes, the free plan includes 3 generations per month and browser study, and you do not need a credit card to start.
