Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
