Supertext AI translation for WordPress (WPML)
AI translation into your WPML languages, professional translation orders and XLIFF/HTML translation files
Using Polylang instead of WPML? There is a Supertext plugin for Polylang too. Supertext for Polylang →

How it works
For AI translation, editors open a post or page and click Translate next to a language in the Supertext box. Supertext translates the title, the content block by block, the excerpt, the custom fields WPML translates and untranslated categories and tags, and creates the translation as a draft linked to the original in WPML. Translate again replaces an existing translation after a warning. In the Posts or Pages list, the Supertext AI Translation bulk action translates many posts at once and never overwrites existing translations.
For professional translation, editors choose Supertext Human Translation in the bulk actions, pick a language and translation type, and select a delivery option with its quoted price. When Supertext delivers, the translation is written into WPML automatically and tracked on the Orders page.
WPML has no interface for third-party machine translation services, so Supertext brings its own box and bulk actions instead of appearing inside WPML's translation editor. The plugin is independent of the Polylang one.

About WordPress (WPML)
WordPress is the most widely used open source content management system, written in PHP and powering everything from personal blogs to large corporate sites. WPML (WPML Multilingual CMS) is the most widely used commercial plugin for multilingual WordPress sites: it links posts, pages, taxonomies and custom fields across languages and comes with its own translation management.
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
WPML translates with its own AI engine, PTC, and has made DeepL, Google and Microsoft “legacy”; by default its automatic translations are published without review. Supertext creates drafts linked in WPML for you to check, into Swiss variants with formal address, hosted in Switzerland, and orders professional translation when a text has to be perfect.
