How do I detect plagiarism with viper?
Viper allows educators to determine if electronic essays are plagiarised. (photo blue screen 1 image by Aleksandar Radovanovic from

Viper is an anti-plagiarism software program for Microsoft Windows operating systems. It is free to download, free to use and allows for three different scanning modes. Users may choose between scanning against files on their own computer (useful primarily to check for self-plagiarism, or if you suspect two students of collaboration) and scanning against the Internet to see if the source document is in any way plagiarised. The latter usage is by far the most common application.

Skill level:


  1. 1

    Download and install Viper anti-plagiarism scanner (see Resources). Run the program for the first time and create a user profile.

  2. 2

    Run Viper, and provide your newly gained login information. On the initial screen, click the "Add" button. Direct the program to the path housing the document to be scanned for plagiarism. Choose an appropriate category for the document from the drop-down menu that is presented, then click the "Done" button.

  3. 3

    Click the button marked "Go to step 2." If you wish to scan the student's document against files on your own computer, click the "Search in local databases" box and then click the "Manage local databases" button. Direct the path toward the file folder containing the documents you wish to scan the student's essay.

  4. 4

    Click the button marked "Go to step 3." Ensure that the "Search in the Internet" box is checked off and then click "Start!"

  5. 5

    Wait for the scan to complete. A plagiarism ratio percentage will appear on the left-hand side of the application window, indicating the strength and occurrence of the plagiarism present in the source document.

Tips and warnings

  • The Viper anti-plagiarism software client does most of the processing of information through a central online server. You must be online to use the software client.
