Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for model-shopping. I use this for every prototype before committing.S-tier for designers. The only one that takes vectors seriously.
