Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Not for full songs with vocals Shorter generation limits	Niche use case Pricing ramps fast	Pricey for casual use Fiction-only focus — not for business writing
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	A-tier in its niche. The only one that actually gets emotion right.	S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.
