AI-powered translation platform that combines machine translation with human post-editing for scalable, high-quality multilingual customer support
Unbabel is an enterprise AI translation platform in the Language Operations (LangOps) category with custom pricing starting at approximately $100,000+/year, designed for mid-market and large organizations that need scalable, high-quality multilingual customer communication. Founded in Portugal in 2013, Unbabel blends neural machine translation with a distributed community of human post-editors to deliver near-native-quality translations across dozens of languages for global enterprises.
The platform's architecture is built around a hybrid pipeline. Source text first passes through Unbabel's proprietary machine translation stack, which selects from a portfolio of engines — including its own LLM-based models and third-party neural MT systems — to produce an initial translation. That draft is then scored by a Quality Estimation (QE) model, one of the core pieces of Unbabel's intellectual property, which predicts translation quality at the segment level. High-confidence segments are delivered immediately; lower-confidence segments are routed to human post-editors drawn from Unbabel's global community for correction before delivery. This selective routing keeps costs and turnaround times lower than full human translation while maintaining quality well above raw machine translation.
