Depending on the job you need doing, it’s a generative engine optimization (GEO) tool, a ChatGPT SEO tool, or an AI rank tracker.
How it works
You browse ChatGPT the way you always do. When an answer finishes, you click the fox in your toolbar, and FanoutFox reads that answer’s traffic the same way I’ve been reading it by hand, then lays it out in plain language.
Everything stays in your browser. There’s no account and nothing runs on a server.
Two ways to install
Chrome Web Store
The easy path, one click and automatic updates, and it’s where most people should start.
Manual download
The same code with no review queue in front of it. When ChatGPT breaks something, the fix goes up the moment it’s ready.
The changelog records every release and whether it’s live on the store yet.
