Make flashcards automatically from your own PDFs and notes
Upload a chapter, lecture slides or photos of your notes and DeckOwl builds a deck of flashcards you can review on a spaced repetition schedule.
How an automatic flashcard maker with AI fits into studying
Writing flashcards by hand can take longer than the reading they summarize. An automatic flashcard maker with AI reads your own material and turns key terms, definitions and processes into question and answer cards, so you spend your time recalling instead of typing.
- Turns PDFs, slides, documents and photographed pages into cards
- Adds spaced repetition so review time follows what you forget
- Free plan includes 3 generations per month and browser study
- Paid plans add unlimited generations and Anki, CSV, PDF and DOCX export
Reads the files you already have
Upload PDF, DOCX, PPTX, plain text or images. Photos of pages are read with text recognition, so handwritten-to-typed notes can still become cards.
Spaced repetition built in
Cards you find hard come back sooner, and cards you know well are spaced further apart, so review time goes to the material you are actually forgetting.
Study in the browser or export
Free accounts study in the browser. Paid plans add PDF, DOCX, Anki and CSV export for studying on other devices or in other apps.
How it works
Upload your material
Add a PDF, slide deck, document, text file or photo of your notes. No credit card is needed to start.
Review the generated cards
DeckOwl proposes question and answer cards from your content. Keep the ones that matter and edit any that need tightening.
Study on a spaced schedule
Work through the deck daily. The schedule brings back cards you miss and spaces out the ones you already know.
The quality of the deck depends on the source. Use the chapter or lecture you are actually being tested on, check each card against the original, and delete anything trivial. Ten strong cards from the right section beat a hundred copied from a loose page of notes.
Spaced repetition does the rest. Reviewing each card just before you would forget it builds long-term recall more efficiently than rereading, and the schedule adjusts to what you miss.

Frequently asked questions
How many flashcards should I make from one chapter?
Most chapters work well with 20 to 40 cards, each focused on a single idea. Start with key terms and definitions, then add cards for processes and comparisons you tend to mix up.
How do I check that the automatic cards are accurate?
Compare each card with the source passage before you start studying, especially for numbers, dates and dosages. Edit or delete any card that is vague, misleading or missing context.
Can I export the flashcards I generate?
Exports are part of the paid plans. Plus includes PDF, DOCX, Anki and CSV export, and Pro adds QTI 2.1 and Moodle XML, while the free plan lets you study in the browser.
What file types can I upload?
You can upload PDF, DOCX, PPTX, plain text notes and images, and photos of pages are read with text recognition. Free accounts get 3 generations per month.
