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 model-shopping. I use this for every prototype before committing.B-tier. Still early. Manus is more flexible for less money.
