Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.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.
