Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier in its category. The first AI music tool I'd actually listen to.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier for solo + free. The best free option, hands down.
