Kagi does this really nicely, you just add a question mark at the end and it'll add on top of the search results an LLM summary of what's been found. It's subpar in quality but more than enough to aggregate the results by theme

Yeah you'd need to support it in the term itself. So many queries coming from the url bar. As opposed to a toggle or something. I wonder if we have info on that - what percentage is input in address bar vs google homepage/app.

The problem is that's not discoverable though. The toggle on google.com would be nice but most people probably arent searching that way.
