Bo pulls the labeled diagrams out of your own slides, scans, and photos, then masks them. Not one image you paste, your entire course.
AI Image Occlusion

How Bo makes it.
01
Upload the lecture
Slides, a scanned atlas, a photo of a page. Bo pulls out the labeled diagrams.
02
Bo masks every label
Every printed label, boxed automatically. One card per diagram.
03
Study it, or send it to Anki
Recall in-app, or export to Anki's native Image Occlusion and a print-ready PDF.
Study it
Quiz the diagram, not a copy of it.
Cover everything and recall the whole picture, or reveal one label at a time.

It leaves the app clean.
Native Anki Image Occlusion
Export to Anki's built-in Image Occlusion note type. Cards open in Anki's own editor with no add-on, one editable note per diagram.
Print-ready PDF
Every diagram as a clean worksheet. Hide-all to quiz yourself, then check against the answer sheet.
Cover, don't reread
Reading the label isn't recall. Covering it is.
It remembers
It tracks the labels you keep missing.
Every diagram you study feeds your course mastery, so Bo knows which labels you keep blanking on and brings them back sooner.

FAQ
Questions, answered.
No. That is the whole point. Bo detects every printed label on the diagram and masks it for you. If a box needs nudging there is a drag-and-resize editor, but you start from a finished deck, not a blank canvas.
Yes, to Anki's built-in Image Occlusion note type, so the cards open in Anki's own image-occlusion editor with no add-on. One editable note per diagram, and Anki generates a card per label.
Anything with printed labels: anatomy, histology, cell and plant biology, neuroanatomy, labeled processes and cycles, maps. If the diagram has callout labels, Bo can occlude them.
Your own uploads. Bo crops the figures out of your slides or scans during processing. Nothing is generated or pulled from the internet.
