Kai's verdictB-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.S-tier for open-source model APIs. The default in this space.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.
