Kai's verdictA-tier for real-time. B-tier for everything else. Worth checking when news breaks.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-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.
