Kai's verdictB-tier. Still early. Manus is more flexible for less money.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. Close second to Cursor. If $5/mo matters, start here.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
