Make flashcards on your phone from notes, PDFs, or photos
Snap a photo of a textbook page or upload a PDF from your phone, and DeckOwl builds flashcards with spaced repetition. The free plan lets you study right in your phone's browser.
Making flashcards on your phone, step by step
Between classes or on a bus, a phone is often the only device nearby, so it helps to make flashcards on your phone without a laptop or a stack of index cards.
- Keep each card to one question or term.
- Photograph pages in good light so the text is readable.
- Review a short session daily rather than one long cram.
- Export to Anki or PDF on a paid plan if you want cards outside the browser.
Start from a photo
Photos of pages are read with text recognition, so a snapshot of a textbook or handout becomes a card deck.
Upload what you already have
PDF, DOCX, PPTX, plain text notes, and images all work as input.
Review with spaced repetition
Cards come back at the intervals your memory needs, so you review less and remember more.
How it works
Capture or upload
Take a photo of your notes or choose a PDF or slide deck saved on your phone.
Generate the cards
DeckOwl turns the material into flashcards ready for spaced repetition.
Study on the go
Open the deck in your phone's browser and review during the commute or a short break.
You do not need a printer. Photograph a page of notes, upload a PDF or slide deck, and DeckOwl generates flashcards you can review in your phone's browser. The free plan includes 3 generations per month and browser study, while exports to PDF, DOCX, Anki, and CSV are part of the paid plans.
Good phone cards are short: one fact per front, with an answer you can check in a line or two so each review takes seconds.

Frequently asked questions
How many flashcards should I make from one lecture?
Aim for roughly 10 to 20 cards per lecture, focusing on terms, definitions, and cause-and-effect relationships. Cover the most testable ideas first and skip repeated details.
What makes a good flashcard for studying biology on a phone?
Ask one specific question per card, such as the function of an organelle, and keep the answer short. Cards that need a full paragraph to answer are hard to review in a few minutes.
