Content checks#

The checks understand word forms, stop words and readability rules in 9 languages: English, German, Dutch, French, Italian, Spanish, Portuguese, Bosnian (also Croatian and Serbian in Latin script) and Arabic (right to left). Reading ease and passive voice are measured in English, German, Dutch, French, Italian, Spanish and Portuguese.

Translations#

Core SEO and Core SEO Premium are translated into English, German, Dutch, French, Italian, Spanish, Portuguese (Brazil), Bosnian, Croatian and Arabic. The plugin follows your WordPress language.

WPML and Polylang#

On multilingual sites, every page is checked in its own language. The AI writes in the language of each page, unless you set a language under AI settings.
