Simext is a simple software application that generates multiple similar documents from the original document by replacing original words with synonym words. This application could be useful for any person associated with the composition or public reading of text, eg. students, teachers, authors, politicians etc.
!Warning: Τhe automatic generator is far from being accurate in the meaning of the sentences that compose the new document. The best practise is to use the "Synonyms replace..." tool (or just right-click any word) and select new words from the list.
