Machine Translation

Memsource Translate

Memsource Translate uses AI to automatically select the optimal MT engine for your translation jobs, based on each job's domain and language pair. It includes Machine Translation Quality Estimation (MTQE) which supports many language pairs.

  • 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 MT engines supported by Memsource Translate.

  • 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 do not include more characters.

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