> Gemini in Chrome can now work across multiple tabs, so you can quickly compare and summarize information across multiple websites to find what you need.

I noticed the other day that my own Chrome browser had begun doing something almost-but-not-quite like this, specifically in the context of browser-chrome-level search autocomplete.

Typing in the omnibar now seems to offer completion suggestions based on (seemingly) 1. feeding a fulltext extract of all my open tabs into a RAG; 2. doing a search of that RAG using the completion prefix as the query; and then 3. feeding the matched text-chunks to a local (Gemini Nano?) auto-completion suggestion model.

So if I have a tab open somewhere talking about e.g. what type of plants would grow well on a north-facing balcony in Vancouver, and then open a new tab and type "trellace " into the omnibox — then it'll suggest completions seemingly coming specifically from "ideas" it got by reading that open tab. Close the other tab, and those suggestions disappear.

(This might just be an experiment that was pushed to me, though I couldn't find anything specifically referencing it in chrome://flags.)
