The Sketch Engine SDL Trados Studio plugin brings the latest natural language processing (NLP) technology directly into the SDL Trados Studio interface. The translator can easily get information about how a word or phrase is used by native speakers, which collocations it most typically combines with, what synonyms can be used instead and how it is usually translated. The information is based on an automated analysis of multi-billion word text corpora using the ultimate technology from Sketch Engine.

concordance, thesaurus, translations, collocations in SDL Trados Studio

Sketch Engine supports many more languages via the web interface. See the list.


A Word Sketch for the highlighted word displays suggestions of the most typical word combinations as used by native speakers. Examples in context can be displayed with a click of the mouse.


The thesurus generates a list of alternatives for the selected word. The list contains synonyms, antonyms, similar words and words form the same topic area.

term extraction

Our next generation term extraction delivers exceptionally clean results, no manual cleaning required. It is already available through the web interface and will be added to the plugin soon.
