How it works

Three components, all running on Cloudflare's free tier.

01

Chrome extension

Hooks into every navigation via the webNavigation API. Injects block overlays for dangerous sites and warning banners for suspicious ones. No user action needed.

Edge analysis

A Cloudflare Worker runs a 6-signal heuristic engine plus Workers AI (Llama 3.1 8B) for semantic analysis. Combo overrides catch digit substitution attacks like g00gle.xyz instantly.

Community + cache

Verdicts are cached globally via Workers KV. Community votes (Safe / Suspicious / Unsafe) feed back into scoring — one user's detection protects all users worldwide.
