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 for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.
