Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier in its niche. The only one that actually gets emotion right.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.
