A flashcard maker that turns your PDF into study cards
Upload lecture slides, textbook chapters, notes or photos of pages. DeckOwl pulls out the key terms and definitions and schedules reviews so you remember them.
From a PDF to a deck you will actually review
Most course material arrives as a PDF: a lecture deck, a chapter scan or a handout. A flashcard maker from PDF app reads that file and turns key terms and definitions into cards, so you spend your time studying instead of typing. Plain notes, DOCX and PPTX files work the same way.
- Free plan: 3 generations per month, studied in the browser
- Plus: unlimited generations with PDF, DOCX, Anki and CSV export
- Pro: stronger AI model, bulk upload, QTI 2.1 and Moodle XML export
- Students get 40% off with a school email
Upload almost any file
Add PDFs, PPTX slides, DOCX files, plain notes or photos of pages and get cards built from the text.
Spaced repetition built in
Cards return at the intervals your memory needs, so you review what you are about to forget.
Export when you need to
Plus adds PDF, DOCX, Anki and CSV export, so your cards can move into other study tools.
How it works
Upload your PDF
Add a lecture deck, a chapter or a handout. Photos of pages are read with text recognition.
Review the cards
Check the generated flashcards, remove repeats and fix any answer that drifts from the source.
Study on a schedule
Practice in the browser with spaced repetition and come back to the cards that need more work.
Check the output before you study. Remove cards that repeat each other, correct any answer that drifts from the source, and add a card for anything your instructor stressed. Spaced repetition then schedules reviews so the hard cards come back more often.

Frequently asked questions
How many flashcards should I make for the periodic table groups?
Start with one card per group plus one for each element you must recall, which for a single unit is often 20 to 40 cards. Add more only for groups with exceptions you keep missing.
What is the fastest way to memorize the periodic table groups?
Learn the trend first, such as valence electrons and reactivity, then use cards to drill group names and exceptions. Short daily reviews work better than one long session.
Is there a free plan?
Yes. The free plan includes 3 generations per month and browser study, and no credit card is needed to start. Exports require Plus.
Can I export my cards to Anki?
Yes, Anki export is included with Plus, which costs $39/year or $7.99/month. Students can get 40% off with a school email.
