Gemma-4 WebGPU Kernels Tool
A demo running Google's Gemma-4 model directly inside a web browser using your device's graphics hardware — private, on-device AI with no server and no data leaving your machine.
Gemma Gem Tool
A Chrome extension that runs Gemma 4 E2B locally through WebGPU using an ONNX build with 4-bit weights, and gives the resulting agent page-reading, clicking, typing, screenshot and JavaScript tools. Worth knowing before you install: the widely quoted ~500MB is the cached download on disk, and the project's own estimates for GPU and system memory during inference are substantially higher and not benchmarked on real devices.
Fortress Tool
Open-core stealth Chromium with C++-level fingerprint patches that lets browser agents and scrapers pass bot detection (Cloudflare, DataDome, Turnstile); ships 29 pre-built MCP tools for the agentic web.
