Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-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.
