Could you build this?
Partial Building the Chrome extension wrapper is easy, but optimizing and running local quantized LLMs smoothly via WebGPU inside a browser tab requires specialized low-level knowledge of WebGPU runtimes and memory constraints.
What it would actually take: The stack relies on WebGPU, WebAssembly, and libraries like WebLLM / ONNX Runtime Web loading quantized models (e.g., Qwen 0.5B/1.5B) directly into browser VRAM. The difficult parts are managing GPU buffer memory limits inside the Chrome sandbox, preventing main thread freezing during inference, and mapping DOM states into token-efficient visual/textual representations for the on-device agent.

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
