About Plagium

The tool works by submitting text or a document, then searching for matches across the web, news and academic sources, followed by an analysis that highlights passages and links to sources. It presents a verdict and allows users to review matched passages and adjust what to exclude. It emphasizes privacy and transparency in how results are reported.

Plagium offers both quick live web searches and deeper archives searches, and provides a combined report including direct links to sources and highlighted passages. It can also produce a PDF report or a shareable read-only link, and it supports cross-language matching for translated content.

The service outlines multiple pricing and plan options, including free searches, credit-based usage, Unlimited monthly plans, and institutional offerings. It also notes platform compatibility, integration options, and conditions for use, with details on how credits are allocated and how the cost scales with document length.
