Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Not for full songs with vocals Shorter generation limits	Output quality behind Claude for polish SEO automation can produce generic content	Harder to use than hosted tools Needs infra
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.	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.
