Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.
