Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
