Bodylang: open-source 3D anatomy app built with Claude Opus 5.5 to model your own body
samewakefulinsomnia · reddit · 2026-11-08
A developer leveraged Claude Opus 5.5's 3D modeling strength to build Bodylang, an open-source app that lets you chat with, model, and track your own body in 3D throughout the day and across various scenarios — inspired by how unclear 2D biology textbook diagrams are.
The app is early-stage and not all body systems are present yet, but the author finds it genuinely insightful and fun. Live demo at bodylang.vercel.app, code on GitHub. He also runs it as an interactive desktop background on a second monitor via another app called Splash.
