Kai's verdictA-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.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
