Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.B-tier. Useful for first drafts. v0 is the better bet for shipping code.S-tier for builders. The right primitives. What Kai is built on under the hood.
