LyX is a graphical document processor that combines the capabilities of LaTeX with an editing environment focused on document structure rather than visual formatting.
Unlike conventional word processors, LyX encourages writers to identify the purpose of each part of a document, such as a heading, paragraph, quotation or mathematical expression. The application then applies formatting rules consistently throughout the document.
LyX is particularly suited to technical and academic writing, including research papers, books and dissertations. Its document classes also extend to creative writing, with the Hollywood class providing screenplay formatting.
The application is useful for preparing documents that require precise typesetting, mathematical notation, bibliographies or extensive cross-references.
This is free and open source software.
