Anatomy Open-Source: Turns Technical Principles Into Working Machines With Just One Sentence

Beating AI News: Developer Ryan has open-sourced an AI drawing tool called Anatomy, which currently supports Claude Code, OpenCode, and Codex. Users only need to describe the technical concept they want to explain in one sentence, and the AI will automatically design a machine that demonstrates the concept’s principle through moving parts. The generated works can also be operated via mouse or keyboard. For example, when explaining LRU cache (which prioritizes removing the least recently used data), the AI creates a bookshelf that can move books; when explaining how a mechanical watch works, it generates a mechanical device that can wind up, adjust speed, and disassemble gears. More complex works include SpaceX Starship’s Raptor rocket engine, which can be split into 11 components and simulate ignition. Currently, 33 major works are showcased on Anatomy’s official website. Anatomy first studies relevant principles and parameters, then designs parts, creates graphics, and adds animations. The movements and numerical readings in the scene are controlled by the same computational model, changing synchronously during operation. It also has built-in automated inspection tools to detect issues such as part interpenetration and occlusion errors. The final output is editable web code that can be opened independently or embedded into websites. The developer has also packaged existing works into a component library for direct use by developers. The project is open-sourced under the MIT License. However, creating detailed works takes significant time: the mechanical watch took nearly 2 hours to develop, while the Raptor rocket engine took over 10 hours. Its 3D functionality remains in the testing phase.
