Kai's verdictA-tier. Best for teaching a kid to code in 2026.B-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.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
