Companies and their teams are learning how to balance cyber security with productivity and user experience. How can they improve usability and productivity for employees, while keeping their systems safe and their costs low? Single sign-on (SSO) authentication helps companies and employees alike to address these challenges. What is SSO? SSO allows employees to log in to all company applications with one set of user credentials. Users can switch easily between corporate apps without having to generate and remember multiple passwords. SSO setup via Self-Service is now available for DeepL Pro Advanced or Ultimate users with 35+ licenses. Look at what our current customers are saying – and learn how SSO improves security, user experience and productivity. Enhance security and compliance There is a seemingly endless array of apps we use daily. With so much to keep track of, it’s no wonder that most users choose the same or similar passwords for each application (yes, we’re all guilty of it!) While a weak password might make life easier for an employee, it puts companies at risk of cyber-attacks. Hackers can break down defenses app by app if login credentials are weak. With SSO, the team administrator has a central login directory, with complete control over user permissions and access to resources. SSO also helps IT to ensure regulatory compliance by documenting user activity from this central location. Improve user experience SSO is an antidote to password fatigue. With a single login to remember, employees can spend more time focusing on important tasks and less time stressing over yet another new password. Employees can easily request access to new apps in the corporate suite and, if they do forget their master login, they can reset their password quickly and easily. Reduce cost SSO unburdens the IT department from having to constantly reset passwords for multiple apps, reducing overall cost and increasing productivity in other areas of the business. Set up SSO SSO setup via Self-Service is available for our Advanced and Ultimate accounts with 35+ licenses. Administrators can consult our Help Center instructions to set up SSO in less than ten minutes, making it easier than ever to manage their team’s access to DeepL translation products.

With a few days left before the holiday season begins, we want to reflect on our journey over the past 12 months. Our 230-strong team, spread across four different countries, worked extremely hard to realize our mission—breaking down language barriers and bringing cultures closer together. By adding 13 new languages to DeepL Translator earlier this year, we reached 105 million more native speakers worldwide and provided them with natural-sounding, high-quality translations. All thirteen languages are now available on DeepL.com, via the DeepL API, and in our desktop and mobile apps. We also enhanced the file translation feature by adding PDF as a file format. Over 70% of DeepL Pro users requested it in early 2021. And when our users ask, we listen! After releasing it to the public, PDF is now the most popular file format translated on DeepL. Whether you use DeepL in a professional setting or after hours, we want to ensure you can always access our high-quality translations. With the release of our first mobile app for iOS, you can now use DeepL's core functionality on the go. Download the app for free here. Android users shouldn't feel left behind. Our team is currently developing the Android app, which is scheduled for release in Q1 2022. As we grow and welcome more new users year over year, we continuously strive to add new languages and further improve the translation quality provided by our neural networks. This includes advances in the architecture, training methodology and efficiency of the neural networks as well as the intelligent usage of the data that is used in the networks’ training. Last but not least, we continued to invest in our API products this year to enable developers with advanced features. With the recent release of glossary support for the DeepL API, users can specify their translations for words or phrases and customize their translations consistently and at scale. Furthermore, to make it easier for developers to build with the DeepL API, we also released official client libraries in Python and .NET. Read more in the API documentation. On this note, we'd like to thank you for using DeepL. If there's something you've always wanted to see in our product, click here to let us know. We wish you a wonderful holiday season and a great start into the new year! Our real-time file translation feature now supports PDF as a file format. As we continue to provide a best-in-class translation experience for over half a billion people globally, adding the PDF format was important for our community. Over 70% of DeepL Pro users requested it in early 2021. And when our users ask, we listen! Whether it’s an eBook or a document from an international client, you can now translate entire PDF files with just a few clicks. All fonts, images, and formatting remain in place so you can enjoy unbeatable translation quality and increase your efficiency in one go. The number of document translations available to you per month depends on your plan. Free users can translate up to three documents per month (5 MB file size, 100K character limit), while DeepL Pro subscribers have more flexible options. The PDF translation feature is also available for API users who want to build this feature directly into their custom business applications. DeepL uses an Adobe API to convert PDF content to formatted text and then to convert the translated document back to a PDF. It only takes a few seconds, but it’s important to note that your PDF file and the translated document will be sent to Adobe Inc., located in the US, to be converted. The translation will, of course, be performed by DeepL. You can find more information in our Privacy Policy. If you use one of DeepL’s desktop apps, you’ll soon have two options for translating PDF files: Real-time PDF translation is now available via the web translator, the DeepL API, and will soon be available via the desktop apps, DeepL for Windows and DeepL for Mac. Please keep in mind that custom fonts and large image sizes might impact the quality of your translation. If possible, use documents with fewer visual elements to ensure the highest standards of translation. If you need more information, please refer to this Help Center article. Have a PDF you’ve been waiting to translate? You can try it out now on DeepL Translator. We are frequently asked how it is that DeepL Translator often works better than competing systems from major tech companies. There are several reasons for this. Like most translation systems, DeepL Translator translates texts using artificial neural networks. These networks are trained on many millions of translated texts. However, our researchers have been able to make many improvements to the overall neural network methodology, mainly in four areas. It is well known that most publicly available translation systems are direct modifications of the Transformer architecture. Of course, the neural networks of DeepL also contain parts of this architecture, such as attention mechanisms. However, there are also significant differences in the topology of the networks that lead to an overall significant improvement in translation quality over the public research state of the art. We see these differences in network architecture quality clearly when we internally train and compare our architectures and the best known Transformer architectures on the same data. Most of our direct competitors are major tech companies, which have a history of many years developing web crawlers. They therefore have a distinct advantage in the amount of training data available. We, on the other hand, place great emphasis on the targeted acquisition of special training data that helps our network to achieve higher translation quality. For this purpose, we have developed, among other things, special crawlers that automatically find translations on the internet and assess their quality. In public research, training networks are usually trained using the “supervised learning” method. The network is shown different examples over and over again. The network repeatedly compares its own translations with the translations from the training data. If there are discrepancies, the weights of the network are adjusted accordingly. We also use other techniques from other areas of machine learning when training the neural networks. This also allows us to achieve significant improvements. Meanwhile, we (like our largest competitors) train translation networks with many billions of parameters. These networks are so large that they can only be trained in a distributed fashion on very large dedicated compute clusters. However, in our research we attach great importance to the fact that the parameters of the network are used very efficiently. This is how we have managed to achieve a similar translation quality even with our smaller and faster networks. We can therefore also offer very high translation quality to users of our free service. Of course, we are always on the lookout for very good mathematicians and computer scientists who would like to help drive development, further improve DeepL Translator, and break down language barriers around the world. If you also have experience with mathematics and neural network training, and if it fulfills you to work on a product that is used worldwide for free, then please apply to DeepL! We’re excited to announce glossary support for the DeepL API! Glossaries are available to both DeepL API Free and Pro subscribers. You can create an account here if you don’t already have one. We first added glossary support for our web translator and desktop apps in 2020, and it’s become a much-loved feature amongst our users. The use cases are many and varied—whether you’re translating… ...there’s often brand- and industry-specific vocabulary that you need to account for. Glossaries allow you to specify your own translations for words and phrases, making it possible to customize your translations consistently and at scale so you can deliver the best possible results to your users without pushing a bunch of manual work onto your translation and content teams. And it's an especially important capability for us to offer to our API users, who are often building automated translation workflows that, with the help of glossaries, can be automated even further. Glossary support for the API will also make it possible for CAT tool providers with a DeepL plug-in to build glossary functionality into their products. If you’d like to learn how to use glossaries in the API, or you’re ready to get started, you can check out the API documentation. In the rest of this post, we’ll share a bit more about what you can expect from the feature. Currently, glossaries for the API can be created for the same language combinations available for glossaries on the DeepL web translator and desktop apps: Our team is working on adding more language combinations soon. Glossaries created via the DeepL API are distinct from glossaries created via the DeepL web translator and desktop apps. This means that API glossaries can't be used on the web translator and desktop apps and vice versa. And both DeepL API Free and Pro users can create up to 1000 glossaries. The maximum size limit for a glossary is 10 MB. To wrap it up, here’s everything you’ll need to get started with glossaries in the API and to get help if you need it: 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.
