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.A-tier in its niche. The only one that actually gets emotion right.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
