Studying labeled diagrams without a drawing canvas

Many students searching for a flashcard app you can draw on are trying to learn labeled diagrams, where the labels matter more than the picture. DeckOwl does not include a drawing canvas, so you cannot sketch directly on cards. What it does is read the text in your own material, including photos of pages, and turn it into flashcards.

Upload slides or PDFs and generate cards from the labels and definitions in them.
Edit any card before you study so the wording matches your course.
Review cards in the browser on the free plan, or export them to Anki on Plus.
Pair flashcards with a quiz or mind map to check understanding beyond memorizing labels.

Flashcards from your files

Upload PDFs, DOCX or PPTX files, plain notes, or photos of pages, and get question and answer cards.

Spaced repetition

Cards you miss come back sooner, so your review time goes to the material you are weakest on.

Quizzes and mind maps

Test yourself with multiple choice, true/false and short answer questions, or map a topic as a branching diagram.

How it works

Upload your material

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

Generate flashcards

DeckOwl turns the text into question and answer cards you can edit.

Review on a schedule

Study in the browser and let spaced repetition bring back the cards you struggle with.

For anatomy, biology or any subject built on figures, start with the labels in your slides or textbook PDF. Each label can become the front of a card, with its meaning or function on the back. Generate the cards from that file, then review them so the labels you miss return sooner.

The free plan includes 3 generations per month and study in the browser. Plus adds unlimited generations and PDF, DOCX, Anki and CSV export, and Pro adds a stronger AI model and bulk upload.
