Kai's verdictB-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.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
