Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.
