Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for solo + free. The best free option, hands down.A-tier for social/casual. B-tier for serious work. Good entry point.
