Gemini Fanout Explorer

Version 2026-09-22, released 22 September 2026. What changed

A bookmarklet that shows the Google searches Gemini runs behind the scenes for a chat plus every source it cited, live once the answer is stored or on a saved chat. Read-only.

What it shows

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.

Install

Recommended: Drag this button to your bookmarks bar (Cmd+Shift+B on a Mac or Ctrl+Shift+B on Windows shows the bar), then click it on a gemini.google.com chat:

Gemini Fanout Explorer

Or copy this and paste it as the URL of a new bookmark (bookmark any page, right-click it, Edit):

Gemini blocks code loaded from other sites, so unlike the ChatGPT and Claude bookmarklets there is no short auto-updating version here: The whole tool sits inside this one bookmark. It is about 23KB, which some drags and pastes on Windows do not survive, so if the drag does not take, use the copy button and the paste route. The same code is on GitHub at github.com/oritsimu-new/fanout-explorer as gemini-fanout-explorer.bookmarklet.txt.

Version 2026-09-22, released 22 September 2026

Lighter on the rate limit. The reader no longer keeps re-reading a chat that has a stopped or regenerated answer in its history, and it never reads from a background tab. Drag the panel by its toolbar to move it, and pull the bottom right corner to resize it. It opens at the top right, which is awkward on a magnified screen or a narrow window, and where you put it is remembered for next time. Double-click the toolbar to send it back to where it started. Escape closes the panel, the toolbar with the Close button stays pinned to the top while you scroll and the panel can no longer run past the edge of the screen. The panel also shows its build date next to the title, so a stale bookmark is easy to spot.

Which version are you running? Click your bookmark on a chat and look next to the title at the top of the panel. It shows the build date, like v2026-09-22. No date there means you are on a build older than 2026-09-22.

Getting this build. This bookmarklet has all of its code inside the bookmark, so it never changes by itself: Drag or paste it again from this page to move to this build. Opening this page is not enough, the bookmark itself has to be replaced.

If clicking the bookmark does nothing

Use

  1. Live: Open a new chat on gemini.google.com in Chrome, click the bookmark, send your prompt. The queries and cited sources appear once Gemini has finished answering.
  2. Saved chat: Open the chat, click the bookmark. Chats you have read before show at once from a saved copy in your browser.
  3. Two tables: Search queries is the fan-out Gemini hides, Cited sources is every page it cited. Click + on a source to read the snippet and the answer text it backs.
  4. Click a column header to sort. Download queries CSV is one row per query, Download sources CSV is one row per cited page.
  5. The Index tab explains every column, the Types tab what Gemini records for a grounded answer.

The other bookmarklets

There is one of these for each assistant plus a single page with all three: Fanout Explorer, all three. The code for all of them is on GitHub at github.com/oritsimu-new/fanout-explorer.

Sharing

Send a link to this page or the all-three page. It works in Chrome, Edge or Brave, on gemini.google.com (not the app), logged in, on your own chats.
