What Plagiat.pl Sp. z o.o. does

Plagiat.pl Sp. z o.o. is a privately held Polish software company founded in 2001 (per company-stated 24 years of operation as of 2025), headquartered in Warsaw at ul. Gdańska 2/67, that develops and operates the Antyplagiat anti-plagiarism platform. The company employs 15-20 staff and serves approximately 1,500 universities and 400 publishing houses or businesses, with a cumulative base of 13.3 million+ documents checked over its operating history. Its core product is a proprietary text-similarity detection algorithm that compares submitted documents against internet resources and a shared institutional database, with a dedicated AI-generated content detection module launched in July 2025 to address paper mills. The system supports .doc, .ppt, and .pdf files, generates similarity reports with highlighted borrowed passages, and is available in Polish, Ukrainian, Kazakh, Romanian, and other languages under the StrikePlagiarism international brand.

The business operates a hybrid revenue model combining institutional subscription licenses (annual or multi-year contracts with universities, schools, and businesses) and pay-per-check pricing for individual users starting at 1 PLN per page through the sprawdz-prace.plagiat.pl self-serve portal. Go-to-market is sales-led: direct enterprise sales in Poland complemented by country-specific offices in Kazakhstan, Ukraine, and Spain, plus channel partnerships such as eThink Education for global Moodle LMS distribution and memoranda with ministries of education (notably Ukraine in 2018). The customer base spans four verticals — higher education (primary), K-12 schools, business/publishers, and individual users — with the Inter-University Document Exchange Program creating a data flywheel where member institutions expand their comparison corpora collectively.

Commercially the company is the undisputed market leader in Poland and Romania, and operates internationally under the StrikePlagiarism brand across Europe, Central Asia, the Caucasus, Africa, and South America (12+ countries). The product integrates with national ministerial anti-plagiarism systems and the Moodle LMS (100M+ users in 228 countries). Ownership and revenue figures are not publicly disclosed; the company has operated continuously without external funding rounds for 24 years and reports a registered share capital of 51,875 PLN, suggesting a profitable, founder-controlled business.
