Kai's verdictA-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.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 for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
