Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Close second to Cursor. If $5/mo matters, start here.S-tier if you're on Mac. The fastest way to get AI answers without context-switching.S-tier for realtime. If latency matters more than voice catalog, start here.
