Kai's verdictA-tier for creators training custom looks. B-tier for general use.A-tier for sales teams. B-tier for solo users.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
