Product Overview: DeepL API is a translation API that allows DeepL's high-precision AI translation technology to be embedded into websites, apps, and business systems. Designed as an enterprise-grade translation API, it supports the construction of multilingual environments. A major feature of the translation is its ability to generate natural, high-quality translations that consider context, tone, and the nuances of the original text, rather than simple word replacement.

It also supports the translation of text containing HTML and XML markup, streamlining the translation process for websites and applications. Additionally, its automatic language detection function allows translation without specifying the source language in advance.

DeepL API for Voice combines speech recognition, translation, and speech output to enable real-time conversation translation, supporting multilingual communication in various scenarios such as online meetings, telephone calls, and face-to-face interactions.

Furthermore, DeepL API is provided under strict data protection standards; translated text is deleted without being saved after translation. This enables secure multilingual support for companies and supports global business expansion.
