We’re excited to announce the release of our Python client library for the DeepL API. This is the first programming language-specific library we’ve built for the API, and our goal is to make it much easier for developers working with Python to build applications with DeepL. Just how much easier? Here's a text translation example. What used to be: Is now: We intend to support all functions of the DeepL API with the Python library, though support for new features may be added to the Python library after they're added to the API. If that’s all you needed to hear, and you’d like to get started right away, you can find the Python client library and documentation here. (By the way: you'll need an API authentication key to use the Python library. If you don't yet have a key, you can sign up for a Free or Pro API plan here.) In the rest of this post, we’ll share more about the Python library project and how you can get involved. Python was an ideal fit for our first client library. It's one of the most widely used programming languages in the world, and it’s popular amongst our API user base. It’s also a language that we have a lot of experience with at DeepL. That said, use cases for the DeepL API are wide ranging, and there are many languages beyond Python that are important to our users. We’re exploring other client libraries we might develop in the future, and if you have any feedback on the languages that are most important to you, please get in touch and let us know. The Python client library is also DeepL’s first ever open source project. We’re always looking for new ways to learn from our users and ensure that our products are solving real problems for them. We believe that open sourcing the project is the best way to foster transparent discussion about what users need and what problems they’re running into, and we encourage you to create an issue if you have ideas or feedback. Of course, GitHub issues isn’t the right place for every challenge you might run into while working with the Python library. If your help request includes sensitive data, please contact our support team. We’re happy to help. To recap, if you’d like to get started with DeepL’s Python client library, you can: Thanks for reading. We’re excited to see what you build. Have you ever wished for instant fluency in another language? Maybe you were traveling and couldn’t read a menu, or you met a new friend but didn’t speak the same language. With our new mobile translation app for iOS, you can say goodbye to language barriers. No matter where you are or who you’re with, you can get your iOS device out and easily access DeepL’s accurate translations. The app is accessible on iPhone and iPad and allows users to translate on the go. It supports all 26 DeepL languages and language variants, as well as other DeepL benefits like fast translations, quick language detection, and best-in-class translation quality. Additionally, you can try the speech to text translation feature, which allows you to use your device’s microphone to translate speech input. It also works the other way around with the text to speech feature, which allows you to listen to your text input and its translation. This is yet another exciting milestone for our team at DeepL as we continue to work towards eliminating language barriers and bringing cultures together. Eager to start translating on your iOS device? You can download the app for free here. We're excited to share that DeepL Translator now supports thirteen new European languages: Bulgarian, Czech, Danish, Estonian, Finnish, Greek, Hungarian, Latvian, Lithuanian, Romanian, Slovak, Slovenian, and Swedish. Over the years, many people have asked us to add more languages to our translator so that they could enjoy DeepL’s accurate translations. We’re thrilled to be able to honor several of those requests at once with the release of the new languages. With this launch, DeepL can now reach an estimated 105 million more native speakers around the world with natural-sounding, high-quality translations. This allows us to further our company vision of breaking down language barriers and bringing cultures closer together. We’re continually working to ensure the translation quality for all languages remains exceptional and that the translation process is seamless for all our users. And if your preferred language isn’t offered yet, don’t worry, we will add more languages in the future. From “Sziasztok” to “Hej”, we’re ready to say hello to our new users and are already looking forward to their feedback. All thirteen languages are now available on DeepL.com, via the DeepL API, and in our desktop apps, DeepL for Windows and DeepL for Mac. Ready to try out the new languages for yourself? Head over to DeepL Translator now to start translating. DeepL has now made it easier to get English translations in your preferred style: DeepL Translator can now produce translations that reflect the particularities of American and British English. Variations in spelling are covered: American neighbors become British neighbours, and they can call each other on their cell phones or on their mobile phones, depending on your preference. Similarly, terms that have completely different equivalents across the pond are also taken into account. American cookies become British biscuits. That is, of course, unless they’re on your web browser. This expanded control over DeepL Translator enables you to more quickly get translations that respect the language conventions that you prefer. To set the language variety you would like, simply select either “English (American)” or “English (British)” as the target language. American and British English are now available as target languages on DeepL.com, via the DeepL API, and in our desktop applications, DeepL for Windows and DeepL for Mac. Combining this feature with other features, such as the Glossary, allows you to take full control of the English texts DeepL Translator produces for you. *Please note that these two language variants are not currently available for translations from Japanese and Chinese. These two source languages will be added in the near future. Since we added Japanese to DeepL Translator, we’ve been amazed by how quickly people in Japan have taken to using our services. We made it a priority to make our paid subscription service, DeepL Pro, available in Japan and we can now announce that that has become a reality. All DeepL Pro subscription plans, providing added data protection, unlimited translation capacity, API access, and more, are now available in Japan. Japanese customers also benefit from prices in Yen. We continue to expand DeepL Pro coverage around the world and will add further countries and currencies in the near future. What’s better than finding the exact right word to express yourself? Always finding the exact right word to express yourself! Our new Glossary feature gives you the power to determine exactly how DeepL Translator should translate terms for you. Whether you translate legal contracts, technical manuals, or company newsletters, the Glossary can save the terms you use and the translations you like, ensuring consistency and saving you time. All you need to do is click on a word in the translated text, click on your preferred formulation, and save the Glossary pair when asked. Alternately, you can click on “Customization” and enter it manually. You can create Glossary entries for nouns, verbs, adjectives, adverbs, and even multi-word entries, and DeepL Translator will adapt the grammar and formulation to accommodate your preferences. You always have the option to turn the Customization feature on or off, giving you full control over how and when the rules you create affect DeepL Translator. Free users of DeepL Translator can create a limited number of Glossary pairs, whereas DeepL Pro subscribers can create as many as they like! Currently, Glossary pairs can be created for the following language combinations: German into English, French into English, English into German, and English into French. Further language combinations will be added in the near future, as will further options to customize DeepL Translator’s results and make the translations your own. We are delighted to announce that DeepL Pro is now available in the Land of the Free and the True North! This has been a longstanding goal of ours and we are very proud to welcome our American and Canadian friends. All DeepL Pro subscription plans, providing added data protection, unlimited translation capacity, API access, and more, are available immediately. Additionally, we are very happy to allow our North-America-based clients to pay for their DeepL Pro subscriptions in their local currencies, US and Canadian dollars. We’re constantly working to enter new markets and will be making DeepL Pro available in further countries in the near future. Please note that while businesses in Quebec may sign up as of today, registration will be open for private citizens shortly. Que legal! DeepL Translator is now also capable of translating into Brazilian Portuguese! The Portuguese language, in all its varieties, is spoken all around the world by millions of people on several continents. The country with the most Lusophones is by far Brazil, with over 200 million people. To reflect some of this linguistic diversity, our researchers have taught our algorithms to also produce translations in the variety of Portuguese used in Brazil. This allows DeepL Translator to capture the nuances and unique vocabulary of Brazil, as well as the language of millions more in Portugal, Angola, Mozambique, and elsewhere. Some variations in the Portuguese language are clear to see in the translations of the phrase “The girl is having breakfast.” Portuguese: A rapariga está a tomar o pequeno-almoço.Brazilian Portuguese: A menina está tomando o café da manhã. The terms for “the girl” (a rapariga/a menina) and “breakfast” (o pequeno-almoço/o café da manhã) reflect regional variations, as does the form of the verb tomar; Brazilian Portuguese prefers the gerund, whereas a construction using the infinitive is more common in Portugal and other countries. The two variations of Portuguese are now available on DeepL.com. To select the version you prefer, simply click on the language next to “Translate into” and select either “Portuguese” or “Portuguese (Brazilian).” Enjoy the many delights of the Portuguese-speaking world! Two of the questions we are most often asked are, “when will you add Japanese?” and “when will you add Chinese?” We are pleased to say, "今日！" Or, "今天！" The improvements in our neural network architecture that we made early this year have enabled us to achieve translation quality in Japanese and Chinese unlike anything we’ve seen before. To be sure the translations lived up to DeepL’s standards, we once again ran blind tests: We asked Japanese and Chinese translators to evaluate a set of translated texts from various online translation providers, without knowing which site produced which translation. Once again, DeepL’s results were picked as the best more often than any other provider’s, as you can see below: These two languages and their unique writing systems, posed interesting challenges for our research team. How do you teach a machine to translate to and from languages that are so different from one another? The answer is found in millions of translations, clever mathematics, and invaluable input from our Chinese and Japanese language experts. The result is an important expansion of DeepL Translator’s capabilities. The algorithms can now handle several thousand Chinese characters, as well as Japanese kanji, hiragana, and katakana. With this vast knowledge, DeepL Translator can now produce translations that use natural-sounding, context-appropriate language in two more of the world’s most-used languages. This is an important milestone for us; adding Japanese and Chinese expands our language coverage to over a billion potential new users. We are very proud to have been able to respond to the wishes of people around the world and fulfil our ambition to add Japanese and Chinese to DeepL Translator. 気に入っていただけると嬉しいです！ 我们希望你喜欢它！ We are pleased to inform you that, today, we have launched a completely new translation system that represents another quantum leap in translation quality. The neural networks we use are far superior to previous technologies and you can now test and use them free of charge at www.DeepL.com. We already made some headlines in 2017 when we released DeepL Translator, which was superior in quality to translation systems of even large high-tech companies and was able to translate even longer passages without errors. Our services quickly became popular: they are now used by more than half a billion people. Now our AI researchers have succeeded in achieving another breakthrough in translation quality. All the criteria that make for a good translation have been improved by the new system. The new neural networks are able to represent the meaning of the translated sentences in the target language much more precisely and, at the same time, are often able to find more professional formulations. This has prompted us to conduct new blind tests. We translated 119 lengthy passages from a wide variety of subjects using DeepL Translator and some competing systems. We then asked professional translators to evaluate these translations and choose the best translation - without being informed which system produced which translation. The translators selected the translations from DeepL four times more often than those from any other system: We assume that companies such as Google or Microsoft also have very good data for training neural translation networks. On the other hand, we have achieved many innovations in the mathematics and methodology of neural networks, with the help of which we can extend our lead. It is a special moment for our entire team that these improvements can now be used by billions of people. At DeepL, our vision is to break down language barriers worldwide and bring cultures closer together. To achieve this, we are planning to add many more languages and, in the coming months and years, we want to integrate translation technology wherever people communicate with each other, read texts, write or do business with each other. This vision also motivates many AI researchers and developers to join DeepL. If you too would like to help us bring the world closer together, please feel free to apply!
