Kai's verdictS-tier for aesthetics. If you care how it looks more than how it's made, this wins.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for builders. The right primitives. What Kai is built on under the hood.S-tier for open-source model APIs. The default in this space.
