Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for open-source model APIs. The default in this space.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
