StudyTokHow to make flashcards from a photo
You can turn a photo of a page into a deck of flashcards in about a minute. Here is how scanning works, how to take a photo that gives clean results and what to check afterwards.
How photo-to-flashcards works
An AI model first reads the text in the picture, including printed text and many styles of handwriting. It then decides which statements are worth memorizing and rewrites them as question-and-answer pairs. You end up with a deck you can study immediately instead of a page you still have to process by hand.
How to take a photo that scans well
- Use even light. Shadows across the page are the most common cause of missed words. Face a window or lamp so your hand and phone do not cast a shadow.
- Hold the phone parallel to the page. A steep angle squeezes the text at the far edge.
- Fill the frame. Get close enough that the text is large, but keep all four corners of the page visible.
- Flatten the page. Curved book gutters distort lines. Press the book open or scan one half at a time.
- One topic per photo. A page about one subject gives a more focused deck than a messy spread.
What to check after scanning
AI cards are a very good first draft, not a finished product. Spend a minute on each batch: delete cards that test trivia, fix any word the model misread (names and formulas deserve a glance) and merge cards that ask the same thing twice. This review is also your first exposure to the material, so it is not wasted time.
What works best
Dense, fact-heavy pages produce the best decks: lecture notes, summary sheets, vocabulary lists, textbook sections with definitions and processes. Pure diagrams, full-page photos with tiny print or heavily decorated pages work less well, so consider typing a caption or scanning the surrounding text instead.
From scan to study session
In StudyTok the flow is: open the scanner, take the photo, review the generated cards, save them into a deck and start studying. Spaced repetition then schedules each card for you, so you see hard cards more often and easy cards less. The decks are stored on your phone, so you can study offline afterwards.
