Don't just see the heart.
Understand why it fails.

🫀 Mechanism, not just anatomy

Causal-chain walkthroughs with Socratic prediction gates — the agent asks "what do you think happens next?" before revealing the answer, so it sticks. Starting with cardiovascular disease, growing from there.

🎨 Four classic atlas styles, live

Flip one heart between Netter, Rohen, Sobotta, and Grant's rendering styles in real time — the visual language you'll actually see in your textbooks and on the wards.

🧭 9 body systems in 3D

Dissect layer by layer, toggle vessels/nerves/skeleton in context, and zoom continuously from organ down to tissue.

✓ Cited, and honestly trust-labeled

Every clinical claim resolves to a real source. Content is clearly marked agent-checked vs. expert-validated — never dressed up as more certain than it is.

Pre-health & nursing students

Build real spatial understanding before lab, and drill the causal chains — not just labels — that show up on exams.

Med & allied-health trainees

Go past "what is it" to "why does it fail" — the mechanism walkthroughs are built for exactly this jump.

Career-changers & lifelong learners

No prerequisite. The guided agent teaches by asking, meeting you at whatever level you're starting from.
