title_body: Is there any tool I can use to examine the differences between two OCR pdfs? I have pdf's to two solutions manuals for a textbook, and I'm trying to determine how much they differ by analyzing both copies with some sort of tool. Does such a thing exist? Is there any other way of determining the differences between two OCR PDF documents?
upvoted_answer: I've done it by converting each PDF to Word, for which there are a bunch of free converters online. Then I use Word's file comparison feature to see the differences: http://support.microsoft.com/kb/306484
