Professionals working in sectors with specific language and jargon have often expressed wishes for the ability to customize the translations they get from DeepL Translator. Legal, technical, and/or scientific terminology, as well as aspects of company style guides, can be entered into the Glossary and will then be correctly and consistently applied in translation. This increased control provides invaluable benefits in terms of accuracy and efficiency.

“We are very pleased to give our users more influence on how our technology works for them,” said DeepL CEO Jaroslaw Kutylowski. “Our new Glossary feature is an exciting advance that gives people more control over machine translation and opens new possibilities for how DeepL’s technology can facilitate communication.”

The Glossary can be viewed at any time by clicking the “Customization” button on DeepL Translator. The user can then add, edit, and delete translation pairs to make sure that the Glossary is always up to date. In future, it will be possible to share Glossaries between team members.

As of today, the ability to influence DeepL Translator’s choice of words is available to DeepL Pro subscribers and free users alike on DeepL.com. Without a subscription, the number of possible Glossary pairs is limited, whereas DeepL Pro subscribers may create as many as they like. The Glossary feature is available for translations between German and English, and English and French, with further language combinations to be added in future.

Press Release — DeepL Translator adds Japanese and Chinese

Cologne, Germany, March 19th, 2020

Germany’s top AI company, DeepL, is proud to now provide machine translation for two of the most highly-anticipated and in-demand languages: Japanese and Chinese.

In Europe and the Americas, DeepL is already known as the world’s best AI translation company. Now, following a long period of intensive research, the company has added two of Asia’s most-spoken languages, with quality exceeding other machine translation systems. “China and Japan are two of the most economically and culturally important countries, so this has been an important goal for us for a long time,” said DeepL CEO Jaroslaw Kutylowski. “Now that our systems produce Chinese and Japanese translations that live up to our standards, we have reached an important milestone in our quest to bring people around the world closer together.”

[...] read more

As always, to ensure the highest quality, DeepL blind-tested their new systems: Japanese and Chinese translators were presented with anonymized translations from DeepL and competitors such as Google, Microsoft, and Chinese giants Baidu and Youdao, and were asked to select the best results.* DeepL once again came out on top in all language combinations.

Achieving high levels of accuracy and natural-sounding Chinese and Japanese translations proved to be an exciting challenge for DeepL’s researchers. On the back of early 2020’s advances in the company’s neural network architecture, the team of mathematicians and computer engineers trained new algorithms on millions of translated texts and sought the insights of DeepL’s Chinese and Japanese language experts to optimize performance.

The result is translation AI familiar with several thousand Chinese characters and Japanese kanji, hiragana, and katakana, and able to recognize the context in which words and phrases occur. DeepL’s systems capture linguistic nuances to produce natural-sounding translations using language relevant to a specific field, such as legal or medical terminology.

Translation to and from Japanese and Chinese is now available free of charge on DeepL.com. The addition of these two languages brings the total number of translation combinations available on DeepL Translator to 110, and expands DeepL’s language coverage to more than 1 billion potential new users.

*Further details about the blind tests can be found at DeepL.com/Blog.

Press Release — DeepL achieves new breakthrough in AI translation quality

Cologne, Germany, February 6th, 2020

German start-up DeepL has released a new translation system that represents a quantum leap in translation quality. The artificial intelligence is far superior to all extant translation technologies and is free to use on www.DeepL.com.

[...] read more

The company made headlines as early as 2017, when it outshone the translation systems of all major high-tech companies with DeepL Translator. For the first time, the newly-designed neural networks were able to translate even longer passages without errors. As a result, the popularity of DeepL grew rapidly: More than half a billion people used its services in 2019.

Today, DeepL is releasing a new translation system based on its many advancements in artificial intelligence. All criteria that make a good translation have been improved by the new system. The meaning of translated sentences is more accurately conveyed in the target language, and, at the same time, the new system often finds more professional formulations.

DeepL's new translation system was also scientifically evaluated in blind tests: 119 lengthy passages from different domains were translated with DeepL Translator and competing systems, such as Google Translate or Microsoft Translator. Professional translators then evaluated these translations and selected the best one - without being informed which system had produced which translation. The translators selected DeepL's translations four times more often than those of any other system.*

DeepL has demonstrated once again that European companies can not only keep up with the world leaders in the field of Deep Learning, but can also set new standards. "We assume that companies such as Google or Microsoft also have very good data for training neural translation networks," says DeepL co-founder and CEO Jaroslaw Kutylowski. "On the other hand, we have achieved many innovations in the mathematics and methodology of neural networks. It is, of course, a special moment for the whole team now that these improvements can be used by billions of people."

DeepL's vision is to break down language barriers worldwide and bring cultures closer together. To achieve this, the company is planning to add many more languages and, in the coming months and years, wants to integrate translation technology wherever people communicate, interact, or do business with each other. This vision also motivates many AI researchers and developers to join DeepL; the number of employees more than doubled in 2019 to 60, and Kutylowski is expecting a further doubling in 2020: "Highly-qualified applicants are naturally always welcome here."

Press Release — DeepL Translator

Cologne, Germany, August 29th, 2017

German tech company DeepL launches DeepL Translator, a breakthrough in neural machine translation that delivers translations of unrivaled quality. From today, it is available to everyone, free of charge on www.DeepL.com.

[...] read more

Despite the money and resources that major internet companies have been pumping into the development of neural networks, it is DeepL that can boast the world's most accurate and natural-sounding machine translation tool. When users enter a text, DeepL’s artificial intelligence is able to capture even the slightest nuances and reproduce them in translation unlike any other service.

In blind tests pitting DeepL Translator against the competition, translators preferred DeepL’s results by a factor of 3:1. Automated tests bear this out, as well. Within the field of machine translation, the gold standard for measuring system performance is the bilingual evaluation understudy (BLEU) score, which compares machine-translated texts with those produced by a translator. DeepL Translator achieves record BLEU scores.*

"We have achieved several significant improvements in neural network architecture," says Gereon Frahling, the company’s founder and CEO. “By arranging the neurons and their connections differently, we have enabled our networks to map natural language more comprehensively than any other neural network to date.”

DeepL’s revolutionary neural architecture runs on a supercomputer in Iceland, 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. “Due to the abundance of renewable energy, we can train our neural networks very cost-efficiently in Iceland. We will continue to invest in high-performance hardware,” explains CTO Jaroslaw Kutylowski.

The DeepL team uses this supercomputer to train neural translation networks on a huge collection of multilingual texts. In training, the networks examine a multitude of translations and learn independently how to translate with correct grammar and structure. Here, DeepL can draw on the success of its first product: Linguee, the world’s largest translation search engine. Over the past decade, DeepL has gathered over a billion high-quality translated texts, the finest possible training material for a neural translation network.

DeepL Translator currently supports 42 language combinations between English, German, French, Spanish, Italian, Polish, and Dutch. The neural networks are already training to master more languages like Mandarin, Japanese, and Russian. DeepL also intends to release an API in the coming months, allowing its superior translations to enhance other products such as digital assistants, dictionaries, language learning apps, and professional translation programs.

“DeepL’s ambitions are not limited to translation,” says Frahling. “Our neural networks have developed a level of text understanding that opens several exciting possibilities.”

*The previous record on the widely-used WMT 2014 newstest set for English-German was 28.4, achieved by the Google research department. On the same set, DeepL’s public translation service obtains a BLEU score of 31.1. For the 2014 newstest set for English-French, DeepL Translator achieves a BLEU score of 44.7, besting the previous record by more than 3 points.
