Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for academic research. Nothing else comes close for systematic reviews.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
