Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.A-tier. Bet on this one — the Sparkpage format is genuinely new.
