| Kai's verdict | S-tier for solo + free. The best free option, hands down. | A-tier for creators training custom looks. B-tier for general use. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. |
