| Kai's verdict | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | 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. | S-tier for academic research. Nothing else comes close for systematic reviews. |
