Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier for sales teams. B-tier for solo users.	S-tier for model-shopping. I use this for every prototype before committing.	S-tier for builders. The right primitives. What Kai is built on under the hood.
