How it works
For AI translation, editors use Polylang's usual translate button, marked with the Supertext logo, to create a linked translation of a post or page. In the Posts or Pages list they can also select several items, choose Supertext AI Translation as the bulk action and pick a target language.
For professional translation, editors choose Supertext Human Translation, pick a language and translation type, and select a delivery option with its quoted price. When Supertext completes the order, the translation is written back automatically as a draft or published post, depending on the settings, and tracked on the Orders page.

About WordPress (Polylang)
WordPress is the most widely used open source content management system, written in PHP and powering everything from personal blogs to large corporate sites. Its large ecosystem of themes and plugins lets site owners extend it without custom development. Multilingual WordPress sites often use Polylang Pro, a commercial plugin that links posts, pages and terms across languages.
Use your own translation tool
Export content as XLIFF 1.2 and HTML, translate it with your agency or CAT tool, and import it back.
Compared with built-in translation
Polylang Pro has DeepL built in, one post at a time, as a draft. Supertext sits right next to DeepL in the same menu, so you can compare both on your own content, and adds professional translation orders when a text has to be perfect.
