Kai's verdictB-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.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.
