Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier. If you're on Vercel/shadcn, this is cheating.A-tier. Bet on this one — the Sparkpage format is genuinely new.
