Kai's verdictA-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for creators training custom looks. B-tier for general use.S-tier for realtime. If latency matters more than voice catalog, start here.
