| Kai's verdict | S-tier for academic research. Nothing else comes close for systematic reviews. | B-tier. Useful for first drafts. v0 is the better bet for shipping code. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | S-tier for builders. The right primitives. What Kai is built on under the hood. |
