Kai's verdictA-tier for creators training custom looks. B-tier for general use.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.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.
