| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for teachers. If you teach K-12, start here this week. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | A-tier for creators training custom looks. B-tier for general use. |
