Kai's verdictB-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.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for builders. The right primitives. What Kai is built on under the hood.
