Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
