| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier. Category leader. Nothing else is close yet. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. | A-tier for creators training custom looks. B-tier for general use. |
