| Kai's verdict | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | B-tier. Still early. Manus is more flexible for less money. | A-tier for designer-led sites. S-tier if animations matter. | A-tier. Close second to Cursor. If $5/mo matters, start here. |
