Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier for social/casual. B-tier for serious work. Good entry point.S-tier in the agent category. The first one I'd give to a non-technical friend.B-tier. Still early. Manus is more flexible for less money.
