A growing share of machine translations are approved - untouched - by human translators in post-editing workflows. But they still cost time and money. Now companies are getting human post-editing quality faster and cheaper, by automatically approving the good machine translations - at human accuracy.

We’ll walk through the motivations, use cases, prerequisites, adopters, providers, integration and ROI.
