All attempts of manipulations are showed up in the Similarity Report. Algorithm can capture paraphrase in all languages.

2

The traits of academic antiplagiarism system is: different types of accounts for different types of users, for example, Student, Coordinator, Admin etc., as well as privacy level.

The volume of the borrowings in % based on chosen criteria. Reports can be easily run by Admins of the corporate (university) accounts without contacting StrikePlagiarism team.

5

6
Use Plagiarism detection system even if you don't have LMS
StrikePlagiarism.com has interface and functionality will no need to have integration to LMS (Moodle, Canvas, Blackboard etc.) if you don't have such and want to save on extra LMS. Our system's interface is designed to replace LMS and make verification process comfortable for any academic and corporative processes. However, StrikePlagiarism.com is integrated to many LMS systems including Moodle and is easy to integrate with any other.

7
Verification based on the linguistic algorithm SmartMarks
We developed a new system algorithm of recognition the nature of the connection between sentences of a text, the composition of text and words separately, thereby to find not only the fact of swapping words, but also replacing words with synonyms, which allows you to find similarity in meaning to a large extent! The system underlines the changed words, and through a pop-up window shows how the word or phrase looked before editing. Here you can find how SmartMarks is indicated at the report.

8
Assessment Protocols (forms)
Our system allows you to add the required fields to the Similarity Report, as well as the Assessment Protocols. These protocols can now be created in any form. The system adds document metadata to the Assessment Protocols automatically after uploading the document for verification, thereby the Protocols are ready for printing and signing immediately after the document is checked for plagiarism.
