Kai's verdictS-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier in its niche. The only one that actually gets emotion right.A-tier for designer-led sites. S-tier if animations matter.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
