Your call: hype or real?

Real = it will matter in daily use. Hype = louder than it is. One vote, and it can’t be changed.

Our view and readers’ views are opinions, not statements of fact about a product.

Why it matters

You copy less data between pages, but the source pages' information is sent to a Gemini model.

For most people

Watch: only in the US and Canada for now.

On a form with at least four text fields, a "Fill from sources" option lets you pick which tabs to use.
Data from the source pages goes to Google's Gemini 3.1 Flash Lite to generate suggestions.
The /watch command monitors a page for sales or new job listings, daily or weekly, while the browser is open.
Watching pauses after 60 days with no change and stops after 90 days.
Both features are in the desktop beta in the US and Canada, with other countries in the coming months.

Try itUseful, but review the tabs you pick before filling.
