Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.B-tier. Still early. Manus is more flexible for less money.S-tier for academic research. Nothing else comes close for systematic reviews.
