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.S-tier infrastructure. The one platform every AI dev eventually uses.S-tier for academic research. Nothing else comes close for systematic reviews.
