Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
