IMPORTANT: The tool is no more actively mantained (exept for its on-going porting to macOS which is the only current activity on this project).
TranslatorBank/CorpusMode* is a free tool designed for professional translators and interpreters to collect and manage monolingual specialized texts from the Web (i.e. building specialized corpora), look them up in an interactive, user-friendly way and find terminological and phraseological information typical of a specific domain. It virtually supports any language, provided the respective resources are available. Out of the box resources are available for English, Italian, German and French.
