Translate your way with the DeepL glossary feature

DeepL users value precision and customizability, which is why our glossary feature is so popular among visitors worldwide.  

You can specify how your words and phrases are translated, saving editing time and ensuring consistency in written communication. DeepL instantly adapts grammar and syntax to your glossary specifications, and you can toggle the feature on and off at any time.

Glossary usage 

The glossary is perfect for using industry or company-specific jargon and gives you customization and control of the translation experience. For example, transportation giant Deutsche Bahn leverages the glossary feature for the DeepL API to standardize terms and phrases across a multinational workforce, ensuring smooth travel for millions of riders year-round. 

No matter your industry, the glossary feature keeps your translations consistent. As the most requested asset among our business customers, we've set our sights on improving the language availability of the feature by adding 8 new language pairs

How does it work? 

On the web translator or desktop apps, click on any word or phrase in the translation you wish to change, and choose from a list of alternatives. DeepL will ask if you'd like to save this translation to always replace the original source word or phrase for the future.

You can also manually enter glossary additions by clicking the Glossary button at the top of the target language box, or upload your own file (only available for Advanced and Ultimate plans).
