Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.S-tier for builders. The right primitives. What Kai is built on under the hood.
