| Kai's verdict | B-tier. Still early. Manus is more flexible for less money. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. | A-tier for social/casual. B-tier for serious work. Good entry point. |
