Overview
Unbabel is a language-operations platform combining machine translation and human review.
What Unbabel does
Unbabel combines translation AI, quality estimation and human language expertise for enterprise content and customer communications. Its Language Operations platform lets organizations set review requirements for different content, markets and risk profiles.
Translation and quality workflows connect automated processing with human review where needed. The company’s technology includes the TowerLLM translation model and COMET evaluation tools, with the operating platform supporting continuing multilingual delivery rather than only one-off translated text.
TransPerfect acquired Unbabel in August 2025 and announced integration of its technology into GlobalLink. Its translation technology now forms part of TransPerfect’s wider language-services and technology offering.
Differentiation
Quality-controlled language operations
The service combines translation with evaluation and configurable review, rather than treating generated text as a finished result in every case.
Current ownership context
Unbabel is part of TransPerfect following the 2025 acquisition, while its language technology remains identifiable within the combined offering.
