Translation connectors


Smartcat connects linguists, companies, and agencies to streamline the translation of any content into any language, on demand. Our platform puts your translation process on autopilot, from content creation to payments.

The extension works by linking your WordPress website to a Smartcat account and pushing the content for translation upon request. After the translation is done in Smartcat — either by yourself, your own volunteers, or hired vendors — it is automatically pulled back to WordPress.

Account & pricing

You need to create a Smartcat account as one is not automatically created when installing the extension. To create an account please visit the signup page at All translation features in Smartcat are free to use.


  • Integrate your WordPress website to a specific Smartcat account
  • Choose the translation vendor

  • Send content to a specific Smartcat project
