About DeepL Translator
DeepL is a machine translation tool whose core purpose is translating text and documents. Users can type text directly to get a translation, or drag and drop documents in common formats such as Word, PowerPoint, Excel, and PDF to translate them while preserving the original formatting and layout. Paid Pro features include Glossaries, Rules, Clarify, and alternatives and phrase suggestions, which help make translations better suited to the context and target audience. For developers, DeepL offers an API that makes it possible to integrate translation into their own systems and business workflows; official client libraries are available for Python, JavaScript, PHP, .NET, Java, and Ruby, and the community also maintains libraries for more languages such as Dart, Go, and Rust. The enterprise edition adds security and compliance capabilities such as encryption, access control, and audit logs, and DeepL states that it complies with GDPR and is SOC 2 Type II certified. Note that the alternatives feature is available in all languages except Chinese (Simplified and Traditional) and is not available to API users.
