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. Bet on this one — the Sparkpage format is genuinely new.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier in the agent category. The first one I'd give to a non-technical friend.
