MonsterWriter is a writing app that let's you focus on composing content instead of worrying about formalities. You do not have to move around headings and images form one page to the other. Inserting a new section at the beginning will not destroy the whole layout of your work. MonsterWriter follows the approach to separate the content composition and the typesetting - bringing the content to a printable page layout. The last part is done automatically by using LaTeX - the most powerful typesetting system available.
