How it works

Turn visual notes into review cards in seconds

Keep the fast OCR workflow from the original page, now in the shared Voovo product landing system.

Step 1

Add your image of any diagram

It could be an anatomy diagram, a biochemical cycle, even a table. Add it from your camera roll, or use Drag & Drop from your book.

Step 2

Voovo scans the image and detects text boxes

If the scan is not 100%, tap Retry Scan and Voovo runs a different text recognition algorithm.

Step 3

Choose what to hide for spaced repetition

Select every text box you want to study later, then choose how much information should be hidden on each flashcard.

Ready when your diagram is

Create image occlusion flashcards without redrawing a thing.
