Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.
