The service provides search against published articles and other resources to match a sample provided by a user or application. It reports other occurrences of text provided to the service across journals, publications, and other published source to allow verification of original work or identify copies of the same text published elsewhere. Uses include verification by academic institutions that work turned in is original to students claiming it and investigation by authors of suspected copying from their work without proper attribution.
API methods support submitting document text to be checked for matches in other published sources. Methods also support managing document collections via folder structures and user accounts. The API returns a similarity report citing locations of text that matches content submitted with the request.
