Zoo (formerly KittyCAD) makes Zoo Design Studio, a CAD app in which every model is defined in its KCL code language and can be edited visually or by its Zookeeper AI agent. Zoo also offers a Text-to-CAD API. Design Studio has a free plan, with paid tiers for heavier AI use; the app's source code is on GitHub.

AI-generated parts still need dimension and tolerance checks before manufacture.
