Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
