Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier. If you're on Vercel/shadcn, this is cheating.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
