What Plagiat.pl is
Plagiat.pl is a web service for checking text originality and protecting intellectual property. Its Antiplagiarism System compares multi-word phrases with internet resources, more than half a million theses, legal acts, a RefBooks collection of one million texts, and an inter-school database exchange. It can identify document changes, characters from other alphabets, and altered whitespace. Similarity Reports show passages that appear borrowed alongside percentage indicators. The system integrates with Editorial System, APD (USOS), Uczelnia XP, OPTIcamp, other school systems, and a Moodle plugin described by the company. Business tools report web addresses where text may be used without authorization, while BookWatch searches for unauthorized online files. Individual-account documents are not added to a database. Reports are generally available within 24 hours, although busy periods can take longer. Individual checks cost $3, paid once per token, covering up to 20,000 characters.
