Overview

Unbabel is a translation platform for companies that serve customers in more than one language. It calls itself a Language Operations platform: one system that manages translation across customer support, marketing and product content. Its logo identifies it as a TransPerfect company, and it is used in gaming, retail, technology and travel, with connectors for Zendesk, Salesforce, Intercom and Freshdesk.

Translation runs through AI-driven workflows. Machine translation handles the content first, and the platform brings in human reviewers where quality needs it, so each workflow can be tuned for speed, quality or cost by market or content type. AI quality estimation scores translations without a human reference and reports on performance. Two related tools are named on the site: Quality Intelligence, which checks the quality of any translation, and MT Score, which compares third-party machine translation models to find the best one for a given language pair.

Pricing is not published. The site has a demo request and a product tour, and cost depends on volume, languages and the amount of human review. The company holds ISO 27001 certification for its security program. Teams should ask how the human review step is priced, since that is the part of the workflow that varies most.

  • AI translation with human review where needed
  • Workflows tuned for speed, quality or cost per market
