Weaknesses	Not for full songs with vocals Shorter generation limits	Less agentic than Cursor/Claude Code Model quality varies	Output quality behind Claude for polish SEO automation can produce generic content	Harder to use than hosted tools Needs infra
Kai's verdict	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.	A-tier. S-tier if you self-host. The reason open-source image gen matters.
