Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.A-tier in its niche. The only one that actually gets emotion right.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.
