How do we compare to the competition?

When talking about our best-in-class translation quality, it's important for us to back up our words with data. Take a look below to see how we measure up against major tech companies.



In 2021, external professional translators were hired to blind review translations from various systems to rate the quality of each translation. In total, they reviewed 119 paragraphs from different domains. The graphs display how often each system's translations received the top rating. Cases where several systems tied for the top rating are not included in the above graphs.
