Press Release — A new approach to translating with DeepL

Cologne, Germany, September 12th, 2019

Germany’s leading AI company, DeepL, today unveils a new way to use their machine translation technology: direct integration into Windows and Mac operating systems. Millions of people enjoy DeepL’s unparalleled translation quality – as evidenced by each day’s 7 billion translated characters. Making the translation technology accessible wherever it’s needed helps DeepL users work even faster.

“The need for high-quality translations is not limited to a website, so neither should the solution be,” said CEO Jaroslaw Kutylowski. “We looked at how our users are translating and created a tool that streamlines the process and expands the scope of where DeepL can be useful.”

The software operates in the background and can be activated with a keyboard shortcut; there’s no need to copy text to the website and back in order to use the translation. The integration creates a direct connection between DeepL and any Windows or Mac computer.

Translations can be called up at any time, without ever leaving the program or application. The user need only select the text to be translated and press ⌘C (Mac) or Ctrl+C (Windows) twice. DeepL then displays the translation, along with alternatives. One final click inserts the translation into the user’s text.

“This integration represents a further step in our quest to provide high-quality AI solutions to everyday language problems,” said Kutylowski. “By opening up new avenues to use DeepL, we hope to see even more people expressing themselves, sharing information, and making new connections.”

The DeepL software supports the same 72 language combinations as on DeepL.com, as well as providing the much-loved alternate translations, synonyms, and other formulations. New languages will automatically become available once added to DeepL. Subscribers to premium service DeepL Pro can sign into their accounts via the software. The software is free to download at DeepL.com/app.

Press Release — DeepL Pro

Cologne, Germany, March 20th, 2018

Last August, DeepL raised the bar for the field of AI translation with the launch of DeepL Translator, whose accuracy left competitors scrambling to catch up. Since then, the company has been inundated by requests from developers and businesses looking to build the next generation of multilingual apps and services. Today sees the response to that demand; DeepL Pro.

DeepL Pro provides an application programming interface (API) for developers, a software plug-in for translators, and an enhanced web translation service. Additionally, DeepL Pro users enjoy excellent data protection; their texts and translations are never stored for any purpose, ensuring full confidentiality.

[...] read more

The long-awaited DeepL API is the platform upon which developers can create exciting new products: Live video and chat translation apps, browser extensions, email clients, augmented reality translators, etc. Integrating the DeepL API into internal business procedures allows global companies to overcome the challenges posed by language barriers.

A further audience for DeepL Pro is professional translators, already using software to better organize and manage their projects. Users of the world-leading SDL Trados Studio 2017 can immediately benefit from incorporating DeepL’s machine translation technology into their workflow, maximizing speed and productivity. With technology handling the grunt work, the translator is free to apply the finishing touches.

DeepL’s position in the AI market is unique. As a company based in Germany, DeepL adheres to the European Union’s world-leading data protection regulations. DeepL Pro subscribers have the added security of knowing that their texts are never stored.

Breaking onto the market last summer with the best machine translation quality yet seen, DeepL’s research and development team has managed to continuously outdo themselves. Record scores in scientific testing have consistently been improved upon.*

“Our neural networks have developed an astounding sense of understanding,” says CEO Dr. Gereon Frahling. “Expect further DeepL products to go far beyond translation and change the way you handle text and speech.”

* The previous BLEU 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, upon the launch of DeepL Translator in August 2017, DeepL obtained a BLEU score of 31.1. In March 2018, the neural networks set a new record of 33.1. DeepL also outperforms the competition in blind testing by professional translators.

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.
