Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier in its category. The first AI music tool I'd actually listen to.S-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
