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 Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.
