How about a feature? Currently, creating "Image Occlusion" cards (where you hide parts of a diagram) usually requires a desktop computer. This feature would bring a mobile-first approach to that:
You take a photo of a textbook diagram or a labeled chart. The app uses on-device AI to automatically detect text labels and "box" them for you.
For non-text parts (like anatomy or a map), you can just use your finger or Apple Pencil to "paint" over an area to hide it.
It turns a 5-minute desktop chore into a 30-second task you can do while sitting in a lecture or a coffee shop.
You simply tap the boxes you want to hide to create cards instantly.
