Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier in its category. The first AI music tool I'd actually listen to.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
