Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.S-tier for realtime. If latency matters more than voice catalog, start here.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
