The idea is you could ask a to browser to do things like operate on multiple websites to do boring stuff, e.g. cross check phone reviews across sites x y and z.
I 100% don't feel comfortable letting my browser work alone, but "agentic browsers" are a thing some people want and/or are building.
A small part of me wants this to spectacularly succeed so I can stop using whatever the army of figma designers wishes to force down my throat when most things I need could be spreadsheets with a few buttons with macros hooked up.
It makes sense as an avenue for Agents as well, since it is the defacto "work app" platform. For many, their entire workday is spent inside the browser.
