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.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier for builders. The right primitives. What Kai is built on under the hood.
