Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.S-tier for speed. When latency is the product, start here.S-tier for builders. The right primitives. What Kai is built on under the hood.
