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.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.
