DeepL Language Translator Expands with Pro Edition and RESTful API

DeepL, a deep learning company that develops AI systems for languages, has announced the launch of DeepL Pro, a fee-based subscription service for language translation. DeepL Pro includes an enhanced web translation service, a RESTful API for developers, and a software plug-in for translators. Texts and translations sent to DeepL are never stored which ensures the privacy and confidentiality of users.

Developers can use the DeepL API to integrate language translation capabilities with web and mobile applications. Examples of use cases for the DeepL API include language translation chatbots and virtual assistants, website and email language translators, and computer-assisted translation (CAT) tools. DeepL has already been integrated with SDL Trados Studio 2017, a translation environment, and users can take advantage of DeepL’s machine translation technology.

DeepL has built a supercomputer in Iceland in order to train neural translation networks on multilingual texts. According to the company website, this supercomputer is capable of “5.1 petaFLOPS (5 100 000 000 000 000 operations per second), enough power to translate a million words in under a second.” The neural translation networks are trained with billions of translated sentences from Linguee, a translation search engine also built by the company.

"Our neural networks have developed an astounding sense of understanding," said Dr. Gereon Frahling, DeepL founder and CEO, in a prepared statement. "Expect further DeepL products to go far beyond translation and change the way you handle text and speech."

Among the languages the DeepL translator service currently supports are English, Dutch, French, German, Italian, Polish, and Spanish. The company is working on training its neural networks to translate additional languages such as Mandarin, Japanese, and Russian.
