Kai's verdictA-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.S-tier for realtime. If latency matters more than voice catalog, start here.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.
