Three free, read-only bookmarklets that show the query fan-out behind an AI answer: the searches ChatGPT, Claude or Gemini runs for a prompt, the pages they get back and which ones they cite. Drag the one you want to your bookmarks bar, then click it on a chat. On Windows, where a dragged bookmark does not always take, use the copy button under each one instead.
| Tool | Where | When it fills | What you get |
|---|---|---|---|
| ChatGPT Fanout Explorer | chatgpt.com | As it answers, a batch of searches at a time. Saved chats too. | Every query on a chat you run with the bookmark open, every page a search returned (cited or not) and which were cited. The freshness window and site limit are no longer sent by ChatGPT |
| Claude Fanout Explorer | claude.ai | As it answers, one search at a time. Saved chats too. | Every query and every page it opens, the pages a search returned (cited or not) and which were cited, exact per query |
| Gemini Fanout Explorer | gemini.google.com | After the answer finishes, not while it types. Saved chats too. | The search queries Gemini normally hides from you, plus every source it cited. It cannot show the other pages it read, because Gemini does not keep them. |
All three read a chat you already have open, live or from your history and keep a copy in your own browser. Nothing about your chats is sent anywhere. Gemini is the one that behaves a little differently: it reveals its searches only after the answer finishes, then shows the sources it cited without the wider pool of pages that ChatGPT and Claude expose.
Version 2026-09-22.8, released 22 September 2026. What changed
Live and saved chats. On a new chat it fills as ChatGPT searches, a batch of several searches at a time, then settles once the answer is done. On a chat from your history it shows the whole fan-out at once. For every search it gives you the pages that came back and which of them were cited. Since September 2026 ChatGPT no longer saves the query text with the chat, so the bookmarklet captures it from the answer as it streams: Click the bookmark before you send the prompt and the queries are kept for that chat. The freshness window and the site limit are no longer sent at all, so those columns are empty on new chats and still filled on chats saved before the change.
ChatGPT Fanout Explorer (short, loads the latest code from GitHub)
To use the copied code: bookmark any page, right-click the bookmark, choose Edit and paste this in as the URL. On Windows this copy and paste route is more reliable than dragging. Full install page and other routes.
Version 2026-09-22.1, released 22 September 2026. What changed
Live and saved chats. On a new chat each search appears as Claude runs it, one query at a time, filling while the answer is written. On a chat from your history it shows at once. For every search and every page Claude opens it gives you the query, the pages that came back and which of them were cited, exact per query.

Version 2026-09-22, released 22 September 2026. What changed
Live and saved chats. Gemini reveals its searches only once the answer is saved, so the panel fills when the answer finishes rather than word by word. It shows two things Gemini keeps out of the interface: the search queries it sent to Google plus every source it cited, with how much of the answer each one backs. Gemini does not expose the pages it read and dropped, a freshness window or a site limit, so those columns from the ChatGPT and Claude tools are not here.
Gemini Fanout Explorer (standalone: Gemini blocks remote code, so the whole tool is in this bookmark)
To use the copied code: bookmark any page, right-click the bookmark, choose Edit and paste this in as the URL. On Windows this copy and paste route is more reliable than dragging. Full install page and other routes.
Each tool has its own install page with the copy and paste routes and the troubleshooting steps: ChatGPT, Claude, Gemini. The code for all three is public on GitHub at github.com/oritsimu-new/fanout-explorer.
