Kai's verdictS-tier infrastructure. The one platform every AI dev eventually uses.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier in its niche. The only one that actually gets emotion right.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
