Kai's verdictS-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.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.
