Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.A-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.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
