Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
