Free computer-aided translation tool

BasicCAT is an open source and free computer-aided translation tool, which aims at providing a simple and useful tool for translators. The name is BasicCAT, because of its simplicity and its programming language—Basic. Basic is easy to learn and everyone can build a suitable CAT tool based on BasicCAT's source code.

The design principle of BasicCAT is to reduce eye shift and focus on translating. Machine Translation, selected word meaning and language check results will all show as a dropdown list below the input textarea.

It comes packed with a dozen of useful features that include autocorrect, quick fill, terminology manager, language check and more.

Beyond its rich functions set, it allows you to add more plugins and extend the translation engine with other services like Google, IBM Watson, Naver Papago, Amazon (offline machine translation) and more.
