Why turn notes into flashcards

Lecture notes pile up quickly, and rereading them rarely shows what you have actually learned. Pasting or uploading your material and getting AI-created flashcards from notes gives you a quiz-style way to test recall right away.

Generate the full set

Works with the files you already have

Upload PDFs, DOCX and PPTX files, plain text notes, or images of pages. Photos are read with text recognition.

Cards built from your own material

Flashcards come from your notes, not a generic deck, so you study exactly what your instructor covered.

Spaced repetition built in

Cards you miss come back more often, and cards you know are spaced further apart.

How it works

Upload your notes

Add a document, slide deck, text file or photo of a page.

Generate your flashcards

DeckOwl reads the material and writes question and answer cards from it.

Study and review

Work through the deck in the browser and let spaced repetition schedule your reviews.

Good cards hold one fact each, with the term or question on the front and the answer on the back. Review them in short sessions, say each answer aloud before you flip, and spend extra time on the cards you keep missing.
