Kai's verdictA-tier for designer-led sites. S-tier if animations matter.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier. If you're on Vercel/shadcn, this is cheating.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
