Commercial TeX Software
(Offered as an informational service only)

Word2TeX is a converter designed in order to use with Microsoft Word and enables Microsoft Word to save documents in LaTeX format. This gives the opportunity to convert existing Microsoft Word documents to LaTeX and to create new LaTeX documents right in your mainstream word processor rather than requiring a completely separate editing environment. Using Word2TeX in conjunction with Microsoft Word, you can easily create articles, technical reports, research papers, dissertations and even entire books for such hard and not always comfortable markup-based system as LaTeX.

TeX2Word is a converter designed in order to use with Microsoft Word and enables Microsoft Word to open documents in TeX format (this includes any TeX-based formats like LaTeX, etc.). This gives the opportunity to convert existing TeX documents to Microsoft Word.
