Gemma Gem is a Chrome extension that runs Google's Gemma 4 model entirely on-device via WebGPU, eliminating API keys and cloud dependencies. It implements a full agent loop with DOM tools (page reading, element clicking, form filling, JavaScript execution) and supports both 500MB and 1.5GB model variants. The architecture uses service workers and offscreen documents to provide on-device agentic AI with complete privacy preservation.
