Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for creators training custom looks. B-tier for general use.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.
