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. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier in its category. The first AI music tool I'd actually listen to.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
