Kai's verdictA-tier. Best for teaching a kid to code in 2026.S-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 overall, A-tier if GDPR/data residency matters. Solid backup option.
