Image Occlusion Flashcards

Some knowledge is spatial: where the aorta is, which country borders which, what each button in your editor does. Image occlusion masks the labels on an image and quizzes you on what's underneath, no Anki add-ons required.

How it works

1. Upload an image

A diagram, a map, a chart, a screenshot. On iPhone and iPad you can pick it straight from your camera.

2. Mask what you want to learn

Draw boxes over the labels, with a mouse on the web or your finger or an Apple Pencil on iPhone and iPad. Type the answer for each region.

3. Let the regions quiz each other

Draw two or more regions and their answers become each other's wrong options automatically. Want different choices? Write your own or have AI draft them.

4. Review on any screen

One image with five masked labels gives you five review moments. They play on the web, iPhone, iPad, and Apple TV, on the same spaced repetition schedule as the rest of your collection.

Where it shines

Anatomy and biology diagrams are the classic use, but occlusion works anywhere a picture has named parts: maps and capitals, the Krebs cycle, circuit boards, sheet music, star charts, or the toolbar of the software you're learning.

Text cards flatten spatial knowledge. Occlusion keeps the structure, so you're not just memorizing a list of planet names, you're remembering where each one sits.

Common questions

Do I need Anki or any add-ons?

No. Image occlusion is built into Interact as a first-class exercise type. Upload, mask, save. There's nothing extra to install or configure.

Does AI create the occlusions for me?

You draw the masks yourself, which takes seconds and keeps you in control of what's worth memorizing. AI can help write the answer choices.

Is it free?

Yes. Creating image occlusions by hand is unlimited on every plan.

What makes a good occlusion image?

A clean, labeled, high-resolution image. Mask one label per region, and mask the parts you'd actually want to be quizzed on rather than everything.
