LaTeX is great and there is no better environment to write professional documents. But spell-checking text within LaTeX is difficult and all projects trying to solve this issue failed at various levels. One of the tools to check for spelling and grammar errors is Microsoft Word. To use MS Word to spell and grammar check LaTeX documents, one has to convert the LaTeX documents to a format readable by MS Word: Rich Text Format (RTF). The latex2rtf project at Sourceforge is transforming LaTeX document to RTF documents. Opening the RTF document using Word allows you to spell and grammar check your document.
