1.7B LLM running entirely in-browser with WebGPU—no servers, no API keys, no per-message costs.

Strengths
  • Inverts cloud-AI deployment assumption by running model on visitor's device.
  • One script tag integration with zero backend or billing setup required.
  • Local RAG keeps user data in-browser with no privacy trade-offs.
Weaknesses
  • 290MB one-time download may impact page load on slower connections.
  • WebGPU browser support limits compatibility to modern devices only.
