A quick look at how Bo turns your own lectures into study material.
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.
Reading the label isn't recall. Covering it is.
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.

Occlusion from your own lectures
- From your whole lecture
- Bo pulls the labeled diagrams out of your own slides, scans, and photos, then masks them. Not one image you paste, your entire course.
- Native Anki, no add-on
- Cards export to Anki's built-in Image Occlusion note type, editable in Anki itself. Nothing trapped in our app, nothing to break on an update.
- One upload, every tool
- The same lecture also becomes flashcards, quizzes, exams, and a study guide, all tagged to the concepts they test.
Questions, answered.
Do I have to draw the masks myself?
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.
Does it export to Anki?
Yes, on Pro and up, 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.
What kind of diagrams work?
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.
Where do the diagrams come from?
Your own uploads. Bo crops the figures out of your slides or scans during processing. Nothing is generated or pulled from the internet.
Can I choose how many?
Yes. Pick the lectures or topics to pull from, and Bo offers up to however many labeled diagrams those actually contain. Choose fewer if you only want the high-yield ones.
