A word processing application, such as Microsoft Word, checks for spelling and grammatical errors with a click of a button. Numerous grammatical online services are also available, including Grammarly, Style Writer and Ginger Software.
Online grammar services offer additional services, like a sentence rephraser, that offers a number of unique ways to write a sentence, as well as a plagiarism checker and vocabulary suggestions. Grammar checkers often contain a dictionary and thesaurus. Writing statistics, word counts and character counts are also offered by numerous services. Finally, online grammar services offer email support. While Microsoft Word's grammar checker is free with the program, most online services charge a monthly fee.
