Kai's verdictB-tier. Still early. Manus is more flexible for less money.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for realtime. If latency matters more than voice catalog, start here.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
