Study diagrams and labeled visuals without rebuilding them by hand
Upload visual material, hide the labels you want to test, and turn diagrams into reusable recall practice much faster than manual recreation.
Visual study usually breaks at the exact point where it should become useful. You have the diagram, the screenshot, or the labeled system in front of you, but turning it into something repeatable takes so much manual work that the whole method gets postponed. Image occlusion fixes that bottleneck.
Upload any visual
Diagrams, anatomy images, maps, charts — upload as-is.
Mask and test yourself
Hide labels or regions and turn the image into active recall.
Reuse across sessions
One image supports multiple prompts, reviewed repeatedly.
Visual study materials are powerful, but manually recreating them is slow and fragile.
If you have to redraw, relabel, or crop everything yourself, visual learning becomes another setup project instead of a repeatable study method.
How you get to review faster
Step 1
Upload the visual
Start from a diagram, anatomy image, map, chart, or labeled process you already use for studying.
Step 2
Mask what you want to recall
Hide labels or visual regions to turn one source image into practical recall prompts.
Step 3
Review the visual repeatedly
Use the same image-based cards across sessions instead of rebuilding your visual study set from scratch.
Why this saves time and keeps visuals useful
Faster setup for visual memory
You spend less time reconstructing images and more time practicing recognition and recall.
Better fit for diagram-heavy subjects
Image occlusion works especially well when labels, structures, and spatial relationships matter.
More reuse from one asset
A single diagram can support multiple prompts instead of becoming one static note.
Who this works best for
Medical and health-science learners reviewing anatomy or labeled systems.
Students working with maps, charts, pathways, or network diagrams.
Anyone whose material is easier to recognize visually than describe from scratch.

Create exam-ready flashcards from your notes in minutes
Paste material from notes, PDF excerpts, docs, or course outlines and turn it into a strong first draft you can refine fast.
Keep reviews sustainable, even when your schedule is not
OxyLesson helps you keep a manageable daily review rhythm instead of letting missed days explode into an impossible queue.
Know whether your study system is actually moving you forward
Progress feels easier to sustain when you can see review consistency, streaks, and weak spots instead of guessing whether your routine is working.
