How this works: every message tries your Pixel 7's local model first, over a private Cloudflare Tunnel. If it's offline or too slow, the router falls back automatically to Cloudflare Workers AI — a Cloudflare-hosted open model, not a frontier model like GPT, Claude, or Gemini. The badge under each reply shows which one actually answered.
Security: your Bearer token and chat history live only in this browser's localStorage — never sent anywhere but the router URL below. Replies from the Pixel stay entirely on your own hardware; replies that fall back to Workers AI leave your device and are processed by Cloudflare's infrastructure (still not a third-party frontier provider).
Web search: when the globe button is on, your message is sent as a search query to Cloudflare's Web Search API (Exa) and the reply always comes from Workers AI, not the Pixel. Sources are listed under the reply.
