Key figures

  • Comparison database — more than 100 million documents.
  • File size limit — up to 50 MB
  • 13,000+ clients, 40+ partner organizations (universities, journals, companies).

Who the service is for

  • Individuals — students, article authors, researchers.
  • Legal entities — universities, journals, companies: user and quota management, check history, billing.

Good to know

  • Most universities and journals accept the report; if needed, the department or editorial office may request additional data.
  • If an individual checks a document in their own account, this does not create a match when the same work is checked on behalf of an organization — unless the work was manually added to the database.
  • The organization or expert decides whether to accept the work based on the check results — each organization may set its own originality thresholds for different document types.
