Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Close second to Cursor. If $5/mo matters, start here.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
