It was used by students to mark content that needed citation and by teachers to detect duplicate risks. However, media has noted that it is not a professional academic review tool, and its results are not highly reliable. After the feature is discontinued, Word will still retain editing capabilities such as grammar correction, spelling checking, and style suggestions.
