Kai's verdict	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	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 reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
