A free Chrome extension that reveals the web-search queries ChatGPT and Claude run when they browse, and the source URLs they cite, captured live and on-device. It makes query fan-out visible, the bridge between a natural-language prompt and what actually gets retrieved and cited. Live on the Chrome Web Store.
What does an AI assistant actually search for when it browses?
When ChatGPT or Claude runs a live web search it silently rewrites your prompt into its own search-engine queries. Those queries, and the sources the assistant then cites, are the bridge between what a user asks and what actually gets retrieved, but they are invisible without sitting in developer tools watching network traffic. This surfaces them live in a popup and an optional on-page ticker, de-duplicated and exportable to CSV.
Why does seeing the fan-out queries matter?
Capturing the queries an assistant issues to the open web, plus the URLs it cites, reveals how prompts are decomposed and reformulated (query fan-out), and which phrasings and entities the model anchors on. That is first-party signal for content and entity optimisation that complements traditional keyword data.
The build itself, reverse-engineering how ChatGPT and Claude stream their responses, is as much the point as the data. Everything stays on the device; no data leaves the machine.
What do the numbers say about search attribution and measurement?
| Metric | Figure | Source |
|---|---|---|
| ChatGPT weekly active users (Oct 2025) | 800 million | TechCrunch |
| Messages sent to ChatGPT per day | 2.5 billion | TechCrunch |
| Monthly users of Google AI Overviews | 2 billion |

How do you try it?
- Add it from the Chrome Web Store in one click, then pin the icon.
- Open ChatGPT or Claude and ask something that needs a live web search.
- Watch the queries and cited sources land in the popup and optional on-page ticker, live.
- Filter by queries or sources, and export the lot to CSV.
