Why we included this project

Gemma Chat is a proof-of-concept for running a coding agent entirely offline on Apple Silicon. It's an Electron app that uses Google's Gemma 4 through Apple's MLX framework, so after a one-time model download you can describe an app and watch the model write out multi-file projects in HTML, CSS, and JavaScript with a live preview updating as it types. No API keys, no cloud calls, and no Wi-Fi once the model is on disk. A separate chat mode adds tool use for web search, URL fetching, a calculator, and bash, and voice input works through in-browser Whisper. The recommended model is about 3 GB, so the whole thing runs on a laptop. This is a working demo rather than a battle-tested production tool, but if your code and prompts should never leave your machine, or you often work where there's no signal, it's a useful place to start.
