Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.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.S-tier for solo + free. The best free option, hands down.
