Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for creators training custom looks. B-tier for general use.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
