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 for fiction. If you're writing a novel, this beats raw ChatGPT every time.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
