Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for designers. The only one that takes vectors seriously.S-tier for model-shopping. I use this for every prototype before committing.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
