Kai's verdictA-tier. Best for fast prototypes. Competitive with Lovable — try both.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
