Kai's verdictA-tier for real-time. B-tier for everything else. Worth checking when news breaks.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.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.
