Kai's verdictA-tier. The most interesting spreadsheet in years. Great for ops dashboards.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for realtime. If latency matters more than voice catalog, start here.B-tier. Still early. Manus is more flexible for less money.
