Features

Copyscape offers both free and paid services for detecting and preventing online plagiarism:

Free Services

  • The free Copyscape service allows users to type in the URL of their web page; Copyscape returns a list of web pages that contain copies of all or parts of this content.
  • Copyscape Banners are freely available to be placed on users' websites in order to warn potential plagiarists against stealing the site's content.
  • Informational resources, links and an online forum allow users to learn more about protecting their Intellectual Property rights online.

Professional Services

  • Copyscape Premium allows an unlimited number of searches. It also allows users to search for copies of their offline content by copying and pasting their text. This is used by online content publishers who need to verify the originality of content they have purchased before posting it on their site. The service also allows users to track the status of cases of plagiarism.
  • The Copysentry service provides ongoing protection for a user's entire website by automatically monitoring the web every day and alerting the user by email whenever new copies are found. The service also allows users to track the status of cases of plagiarism.

Use in Plagiarism Cases

Copyscape has been used in a number of publicized cases to detect online plagiarism. Some examples include:

Design

Copyscape uses the Google Web API to power its searches. Copyscape uses a set of proprietary algorithms to identify copied content even if it has been significantly modified from its original form.

Copyscape is able to find online copies of textual content, but not of images or other media.

Copyscape is not able to determine whether a copy is authorized or unauthorized, nor is it able to determine which of two websites copied the other. Both of these determinations are left up to users.

History

Copyscape was launched in 2004 by Indigo Stream Technologies, Ltd., which was co-founded in 2003 by Gideon Greenspan.[6]
