Kai's verdictS-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
