Kai's verdictS-tier for designers. The only one that takes vectors seriously.S-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.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.
