Label the structure
Tap a masked region to reveal the label
One diagram. Recall practice everywhere.
Add a diagram
In Generate, choose Diagram and drop in up to 10 images: plates, slides, pathways, charts.
Box the labels
Auto-detect finds them for you, or draw and name the boxes yourself. Fix anything in a tap.
Study it everywhere
Each label turns into cards, questions and figures across everything you make from it.
Built into everything you make
Your diagram shows up wherever you study
A diagram is part of your material, like a PDF or a lecture. Whatever you create from that material uses it.
Occlusion flashcards
One card per label. The label is masked, you recall it, then reveal. They join your deck on top of the AI cards.
Quiz and exam questions
“Identify the label” questions built straight from your boxes, mixed in with the rest of the paper.
Lesson figures
Your diagram appears in the lesson section it belongs to, with a check that asks you to name a hidden part.
Notes
The diagrams sit inside your notes next to the text they explain.
Auto-detect
ClassFactor reads the diagram, boxes every label and names it, in seconds. It uses a few credits, and you see the cost before it runs.
Or label it yourself
Draw a box over any label, name it, then move or resize it. Zoom into busy plates and step through every box. On a phone the picture fills the screen and the boxes are one tap away.
