Platform Description

DeepL utilizes deep learning-based neural machine translation (NMT) technology to understand context and provide natural translations. It applies the Transformer architecture to precisely analyze the relationships between words and capture complex meanings. It supports a wide range of document formats, including PDF, Word, and PowerPoint, and can translate while maintaining the layout and formatting of the original, ensuring document quality. DeepL Write supports professional writing by improving grammatical errors, vocabulary choices, and even stylistics, while DeepL Voice reduces language barriers in meetings and consultations with real-time voice translation. We also provide APIs so developers can easily integrate them into their applications or web services, and our fast response times and high availability make us suitable for large-scale services. GDPR compliance and a no-data-storage policy ensure security, and glossary features help you maintain consistent translations and brand tone.

FAQs

  • The DeepL REST API is free to get started, with a monthly translation limit of 500,000 characters and support for one language (out-of-the-box). Higher capacity and features require a paid plan (DeepL API Pro, $5.49/month).
  • Basic text translation is free, and you can upload up to three document files per month for translation (but not editing). However, document translation capacity and advanced features (document editing, glossaries, APIs, etc.) are only available on paid plans.
  • Yes, DeepL uses artificial intelligence technology based on Neural Machine Translation (NMT) to provide natural and accurate translations.
  • While DeepL is a highly accurate machine translation engine, it is not 100% accurate. A 2020 study found that DeepL has an accuracy rate of around 89%, and a study by the Globalization and Localization Association (GALA) reported that it is more accurate than its competitors.
  • You can submit a customer support request from the Help Center or your account dashboard on the DeepL website.
  • Some services are considered better translators than DeepL by some users. For example, Taia's AI translation tool offers translation memory, formatting preservation, and even human translation services that DeepL doesn't have, for added convenience and accuracy. However, DeepL is still rated as the best in the industry for natural context and sentence flow, so your choice may depend on your intended use.
