Query Fan-Out Revealer

See what AI search actually searches for

A browser extension that reveals the real fan-out queries ChatGPT, Claude and Perplexity run behind their answers — and which sources they cited.

The problem

When you ask an AI assistant a question, it rarely searches for what you typed. It quietly expands your prompt into several different searches, reads the results, and writes an answer from a handful of them. That middle step is invisible, and it is where the decisions get made.

What this shows

Observed, not simulated

Most tools in this space guess what an AI system would probably search for, or run their own prompts on a schedule and report back. This one reads the actual response stream in your own browser. What you see is what happened.

Retrieved is not the same as cited

Assistants read far more pages than they quote, and the gap between the two is the useful part. Enter your domain and every answer tells you which side you landed on: retrieved and cited, retrieved but passed over, or never found at all. Those are three different problems with three different fixes, so the extension never blurs them together.

Your metrics, with the working shown

MetricWhat it measures
Retrieval rateHow often your content is found by the AI
Citation rateHow often your content is cited in the answer
Retrieval to citation rateHow often your found content actually gets cited
Mention rateHow often your brand is named, with or without a link

Hover any metric and it shows both the definition and the arithmetic behind the number on screen, so you can check the figure before you report it. Prompts that already name your brand are excluded from mention rate and flagged on the card — an answer echoing your own prompt is not organic visibility.

Private by design

No server, no account, no analytics. The extension reads a copy of the response your browser already received, stores it locally, and sends nothing anywhere.

Measuring brand mentions means the answer text is stored on your computer too. You can switch that off in the panel if you would rather not keep it. Full details in the privacy policy.
