If instead of a copy-pasting spree, or setting up a whateverClaw, the user might just click a button in Chrome, it could be actually useful. (Consider a dozen such buttons.)
Immediately after booking something,I tell Gemini to add it to my TripIt. Works great. I have a little prompt explaining how I like it formatted that I cut and paste, so I can just make this a one-click prompt. I could also have it add flights to my.flightradar24.com.
I also use Gemini in Chrome to add appointment confirmations to my calendar. Or remember things in Google Keep.
There's lot of use cases for this kind of thing.
