Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for realtime. If latency matters more than voice catalog, start here.S-tier if you're on Mac. The fastest way to get AI answers without context-switching.
