LyX

LyX is a unique document processor that bridges the gap between WYSIWYG editors and the power of LaTeX. It uses a 'What You See Is What You Mean' approach, allowing users to write documents in a visual interface while the software handles the underlying LaTeX code. This makes it an excellent choice for academics who want the professional output of LaTeX without the need to memorize complex syntax.

It is highly stable and perfect for long-form documents like dissertations, providing a structured environment that enforces good document design principles.
