## Features

* **Multi-Kernel Support**: Work with Replicad, OpenSCAD, and Zoo (KCL) kernels
* **AI-Powered**: Intelligent CAD model generation with RAG-enhanced assistance
* **Web-Based**: Browser-based CAD modeling with real-time collaboration
* **Export Capabilities**: Support for STL, STEP, and other CAD formats

## Getting Started

Choose your preferred CAD kernel and start building:

* [Replicad](./kernels/replicad) - Parametric TypeScript/JavaScript API backed by OpenCascade.js
* [OpenSCAD](./kernels/openscad) - WebAssembly build of OpenSCAD with `.scad` syntax
* [Zoo (KCL)](./kernels/zoo) - KittyCAD Language for cloud-native CAD with AI integration

## Architecture
