This plagiarism plugin leverages Moodle's plagiarism API to connect to Originality.AI, a premier plagiarism detection tool for online writing within Moodle's core quiz, online text, and forums. 

Unlike many providers, Originality.AI meters by tokens instead of a per-user cost and does not require papers to be submitted to a database. The minimum monthly cost for Originality.AI is less than $20US, making it one of the most cost-effective plagiarism solutions for Moodle LMS.

Installation and configuration documentation can be found here: https://docs.google.com/document/d/1KzYqrmDeGbTCO-JlO2zDSV-cXuVUyeTH03F0buzufyw/edit

The plugin approaches plagiarism uniquely, 

1. it lets teachers choose whether to scan a submission, 
2. it minimizes costs by charging based on usage (rather than "active users" or "FTEs"),
3. it does not upload student submissions to a 3rd party database, and
4. it works on core Moodle activities.

Cursive Technology, Inc. sponsored the development of this plugin. We are unaffiliated with Originality.AI or Passed.AI, but appreciate their work and want to make this solution available to the community.
