Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier in its niche. The only one that actually gets emotion right.A-tier. Best for teaching a kid to code in 2026.S-tier for builders. The right primitives. What Kai is built on under the hood.
