Kai's verdictS-tier for speed. When latency is the product, start here.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.A-tier in its niche. The only one that actually gets emotion right.
