Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for sales teams. B-tier for solo users.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
