Viper is a program that will check your documents for plagiarism, comparing them with millions of others available through the Internet.
It is a necessary tool if you need to submit thesis or papers, which are expected to be 100% free of plagiarism. It is also a great tool for teachers and instructors that must review papers and approve them. This way, they can be sure that the document they are reviewing is not just a "copy & paste job" from a work or works made by other persons, not the submitter.

When you start a search, the program will check the content of your document against a database with more than 10 billion resources. Then, it will highlight the coincidences between your document and those with some similarities. This way, you can compare both documents side by side and introduce in your paper the necessary changes in order to avoid any suspicion of plagiarism.

The program can also check your document for plagiarism against a database of documents already stored in your computer (when available). Once the check is finished, the program will not only show you the results - it will generate a full report that you can save or print.

This software quit working for me months ago. It worked fine at first, then a couple of monthSas later it stopped. Sad because I really did like it now. Now the website is offline and my software still won't connect to the network to even log in.

It's great! but it limits the user's number of words to check. Once per day.

This software doesn't speed up the download at all.
