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 all-rounder. If you want one tool that does everything okay-to-great, this is it.S-tier for open-source model APIs. The default in this space.
