| Kai's verdict | A-tier. Best for teaching a kid to code in 2026. | S-tier for teachers. If you teach K-12, start here this week. | 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. |
