Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier for designer-led sites. S-tier if animations matter.B-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.
