How it works
Upload your material
Add a PDF, slide deck, set of notes, or a photo of a page.
Generate your flashcards
DeckOwl turns the content into question and answer cards you can edit.
Study on a schedule
Review each day and let spaced repetition decide when each card returns.
Good flashcards ask one thing at a time and have a short, checkable answer. Start with the terms and definitions your instructor repeats, then add cards for processes and comparisons, where a single question can hide several steps.
Spaced repetition does the scheduling. Cards you miss return sooner, and cards you know drop out of the rotation, which keeps review sessions short as the exam gets closer.

Frequently asked questions
How many flashcards should I make for a biology unit?
A common approach is one card per term, definition, or process step in the chapter, which often means 30 to 60 cards for a single unit. Start with the most testable material and add more cards as you find gaps.
How do I know which facts belong on a flashcard?
Pick facts you would need to recall without looking at the notes, such as definitions, causes, and steps in order. Keep each answer short enough to check in a few seconds.
Can I export my flashcards to Anki?
Yes, but export is a paid feature. Plus includes PDF, DOCX, Anki, and CSV export, and the free plan lets you study in the browser.
Is there a free plan?
Yes. The free plan includes 3 generations per month and browser study, and you can start without a credit card. Students with a school email get 40% off paid plans.
