Kai's verdictB-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.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
