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.S-tier for designers. The only one that takes vectors seriously.S-tier for realtime. If latency matters more than voice catalog, start here.
