A Chrome extension that analyzes every domain you visit in real time — blocking dangerous sites before you interact with them, powered by AI running on Cloudflare's global network.
Three components, all running on Cloudflare's free tier.
Hooks into every navigation via the webNavigation API. Injects block overlays for dangerous sites and warning banners for suspicious ones. No user action needed.
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.
Verdicts are cached globally via Workers KV. Community votes (Safe / Suspicious / Unsafe) feed back into scoring — one user's detection protects all users worldwide.
These results come from the live Cloudflare Worker. Not simulated.
The Worker is already deployed — you just need the extension.
Clone or download the repo from GitHub and navigate to the extension/ folder.
Open chrome://extensions → enable Developer mode → click Load unpacked → select the extension/ folder.
The shield icon appears in your toolbar. Navigate to any site — dangerous domains are blocked automatically, suspicious ones get a warning banner. Click the icon for the full analysis.
