Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.	S-tier in its category. The first AI music tool I'd actually listen to.	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
