Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for local inference. If you care about privacy or want to tinker, install this today.B-tier. Still early. Manus is more flexible for less money.A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.
