Antiplagiat

What Antiplagiat does

Antiplagiat (Антиплагиат) is a Russian online service, founded in 2005 and headquartered in Moscow, that verifies document originality and detects plagiarism and AI-generated text. Its core product is a web-based checking platform (antiplagiat.ru) offered in tiered packages — a free Demo Check (up to 8,000 characters), FULL L (from 466₽, up to 200,000 characters) and FULL XL (from 1,045₽, up to 2,000,000 characters) — that compares submitted documents against a corpus of 730+ million open-internet sources, 111+ million GARANT legal acts, 15+ million eLIBRARY.RU scientific articles, 1+ million RGB dissertations, and (since June 2026) up to 60 million INVENTORUS scientific articles. The platform applies machine-learning models to identify AI-generated text, paraphrasing and translation plagiarism, and to detect duplicate submissions across institutions.

Underlying capabilities include image-uniqueness checking, translation plagiarism detection, configurable text-exclusion rules, and a Duplicate Detector that flags work previously checked elsewhere. The service is delivered through a product-led growth funnel (free demo, optional self-serve registration since April 2026, Telegram and Max messenger bots) and a dedicated enterprise sales motion for universities, schools, research institutions, media organizations, government agencies and SMBs. Adjacent revenue lines include a paid 1-hour report-analysis consultation (4,000₽), the Antiplagiat.Sputnik education sub-brand (webinars, courses), and the store.antiplagiat.ru marketplace operated by the parent entity AO Antiplagiat GK. Multi-language sites in English, Kazakh, Uzbek, Polish and Belarusian extend reach across CIS and select Eastern European markets.

The legal entity is Акционерное общество «Антиплагиат ГК» (OGRN 1207700453641, INN 7726471130). Antiplagiat is included in the Unified Register of Russian Domestic Software and operates with the support of the National Technology Initiative (НТИ), which positions it as the de facto preferred plagiarism vendor for Russian public-sector and academic procurement. No disclosed funding rounds, parent company, or institutional investors were identified in the input, consistent with a privately held, profitable, founder-controlled firm of 11–50 employees with six named C-level executives across commercial, technical, product, marketing/PR and scientific functions.
