The free grammar checking website and proof reader allows writers to score essays and check their spelling. It also helps them improve their word choices, paraphrasing and grammar, as well as self-assess how they use target structures and English pronunciation. You can also learn from it and become a better proofreader by playing the Error Correction Games. The website can be used at no cost and is completely free of charge. Below is a listing of the site's features. A series of commonly asked questions are located at the bottom of this page. You may find them useful and/or interesting. You can find more information about the website at the blog, or you can watch the webinar on sound ESL pedagogy.
