Programs that check English grammar and spelling include Grammarly, Ginger Grammar Checker and WhiteSmoke. Ginger Grammar Checker and WhiteSmoke function as stand-alone applications, while Grammarly works as a Web browser extension for Google Chrome.
Once it integrates itself with Google Chrome, Grammarly is capable of correcting over 250 grammatical mistakes and analyzing the context of the typed content to correct spelling mistakes accurately. It works automatically in text boxes on social media websites, such as Facebook or LinkedIn, and email services, such as Gmail. WhiteSmoke automatically checks all outgoing email messages that users send via Outlook, and it includes punctuation and style checkers in addition to alerting users about word repetitions or omissions.
