WhiteSmoke is a pioneering software tool that perks up and revises your English writing.

Based on patented natural language processing (NLP) technology, WhiteSmoke executes superior and context-based English grammar, spelling, and punctuation checking, as well as text enrichment to enhance your writing. From well-written letters and emails to friends, through to specialized business citations and presentations. I have been using this tool particularly for blogging to a great extent.
