Kai's verdictA-tier in its niche. The only one that actually gets emotion right.A-tier. No reason not to use it if you're on Figma. Not worth switching for.B-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.
