While technology is amalgamated into educational settings, to use of computer-assisted translation (CAT) as one kind of learning assistant in education contexts is receiving attention. The study introduces one computer-assisted translation (CAT) app, Termsoup, as a way to help learners make a connection between different disciplines or subject areas in ESP (English for Specific Purposes) courses. The study will discuss how the app was employed in a Tourism English course. The app also allows the creation of a corpus and the study will explain how this was done as a way to review student writing and cultivate learners' autonomy. With the aid of CAT, the study hopes to foster learners’ autonomy and enhance students’ ESP writing skills in other disciplines in the future.
