Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.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 search. I use it before Google now. If you're still Googling everything, try this for a week.
