Kai's verdictS-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.S-tier if you're on Mac. The fastest way to get AI answers without context-switching.S-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.
