Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.S-tier for realtime. If latency matters more than voice catalog, start here.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
