This software offers a solution to users who want to find text differences in two PDF files. The user loads the two PDFs and chooses to compare by lines or words. There are options to compare by using standard or MS Word comparison methods. For the latter MS Word must be installed. For the standard comparison method, there are two options: to display all lines, with differences highlighted, or to display only the lines containing differences. Each file loaded can also be saved as a PDF so as to have a copy for editing.
