The majority of people working in the field of technical translations (translation agency project managers, technical documentation department staffers, technical editors, etc.) are in contact with CAT applications on a daily basis. It is not necessary here to describe their function or financial and time-saving advantages in detail.
In my work I utilise studio 2019, Transit NXT, memoQ 8 and Across PE, presently the most widely-used translation applications.
I use ErrorSpy, Verifika application and available plug-ins for the CAT applications themselves to check translations.
