Machine Translation

Memsource Translate

Memsource Translate is the machine translation (MT) hub within Memsource. Its AI-powered MT Autoselect feature finds the optimal engine for each translation job, based on its domain and language pair. Translating can start with Memsource Translate's fully managed engines or supported engines can be added via API. MT Quality Estimation supporting many language pairs is enabled for all engines by default.

  • Memsource Translate is provided in all accounts and is after March 12, 2019, the default machine translation engine.

  • Memsource Translate characters can be used by all Memsource Translate's fully managed engines.

  • Multiple instances of Memsource Translate can not be created.

  • Free characters are included in each edition (Ultimate: 2M, Team and Academic: 500k, Team Start: 250k, Personal: 50k). These characters are for testing purposes and specific to the purchased edition; upgrades or renewals do not include more characters.

  • Once purchased, Memsource Translate characters do not expire. They can be later used after renewing/reviving a subscription.

  • Fully managed engines are presented on the Memsource Translate page or if MT Profiles are enabled, on a profile page. Fully managed engines can be switched on and off from these locations.
