When the Plagiarism Checker generates a report and you don’t see any underline or highlighted sentences, it means that our software has not detected any duplication from all known databases, library, ebooks or archives.
This, however, does not mean that your document is 100% plagiarism-free because we do not have access to offline archives which are non-digitized. If you have any doubt we suggest you to edit or give credit sources accordingly within your document to be on the safe side.
