Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. Best for teaching a kid to code in 2026.
