Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
