Admin guide: installation of Unicheck plugin (Moodle LMS)
Designed based on educators’ feedback, Unicheck is a plagiarism detection engine helping educators spot plagiarism.
It takes a few minutes to set up your account and get the ball rolling. This plugin integrates with assignment, forum and
workshop activities in Moodle to check user-submitted content for plagiarism.
For more information about the Unicheck plugin, please visit the Moodle plugin database page https://moodle.org/plugins/plagiarism_unplag
Go to https://moodle.org/plugins/ and search for Unicheck plugin - ‘Unplag’ (“Unplag” is a previous name of Unicheck).

version is released, simply update the plugin from the Moodle’s admin interface).
Save the plugin locally on your computer and note the path to the saved file.
Log in to Moodle LMS as Admin. Go to Site administration and then to the Plugins sections. Select Install plugins.
Note: Ensure Enable plagiarism plugins option is checked in Site administration → Advanced features. This will allow

Hide sources with a match less than (%)
(0% recommended) Unicheck similarity detection algorithm can find resources where as small as 8 words phrase coincidence can be detected. Use this feature to make search less sensible.
For example, entering "1" will display only those sources, where the percentage of similarity is 1% or more.
Identify citations and references
(ON recommended) Enable this option to find and exclude properly formatted citations and references. Identified citations and references will not be scanned for similarity.

When the option is OFF, we do not store copies of submitted files in your Unicheck.com account, and hence, option
Download original files (student files) will be disabled. We will still be able to find similarity matches with the files, however, you
will not be able to export student submissions as a zip file. By setting this option to ON (default; recommended), you give us
permission to store original documents, submitted by students.
Unicheck global index is a central database that will be shared at some time in the future with all Unicheck customers. Customers
will be able to search against this database and spot similarities. By default, this option is disabled. Users from other organizations
will not be able to view the full text of the documents, we will only highlight the similarities in the user's’ submissions.
This setting only affects Unicheck.com admin account at the unicheck.com. This setting does not affect Unicheck LTI app or
instructor accounts. Keep this option at 0% unless you know what you are doing.
Go to Unicheck.com and log in as admin. Open profile icon → System Settings. Upload the logo in the Design settings section,
