How is Viper different from other plagiarism checkers?

Viper is not suitable for checking plagiarism in books and offline sources because it is mainly designed to compare documents with online content and certain online databases. Its limited database restricts its effectiveness in checking offline sources.

Viper struggles to identify plagiarism from subscription-based platforms like academic journals or premium content providers due to its reliance on publicly available content. Turnitin or Unicheck are more effective for detecting content from subscription-based or paywalled sources due to their partnerships with publishers.

No, Viper is primarily designed to check online sources and has a limited database, which means it cannot effectively check plagiarism for books and offline sources. It focuses mainly on comparing documents to content available on the internet, student papers, and certain online databases.

The number of credits that the user possesses, and the length of each document determines how many documents they can check with Viper. For example,

• Free module: New users can check out for free with up to 5,000 words with one credit.
• Paid module: Documents over 5,000 words require more than one credit.
• Credit bundles: There are credit packages ranging from three to fifty credits. Each credit gets less expensive the more of them you buy.

No, user cannot include certain sources from the Viper plagiarism report, unlike other plagiarism software like Turnitin. This limitation can result in more false positives, especially when citations or commonly used phrases are flagged as plagiarism.
