Whitesmoke is available as a free download from the official website, and comes with an online grammar checker, a full spell-checking feature, auto-corrections and a dictionary. The online grammar checker allows you to search for a particular word and search criteria to find correct synonyms for it. The auto-corrections use the same algorithms that are used by humans, so your spelling will be correct. The dictionary provides extensive coverage for common English words and phrases, so you can research any word or phrase, and instantly access any related information. You can even cross-reference any word or phrase with another dictionary.
