About AI Plagiarism Checker
PlagiarismCheck.org is an originality service that scans a piece of writing for copied material and for AI generated text in the same pass. It compares a submission against publicly available sources and live web search, returns a similarity percentage with every matching passage highlighted against its source, and separately flags sections that read as machine written. The report is interactive and can be downloaded, which suits a workflow where a result has to be shown to a student or filed as evidence.
The detection is built to catch disguised copying as well as direct matches, including word substitutions and rearranged word order or sentence structure. Around that sit a Fingerprint authorship verification tool, a grammar checker, a private institutional archive that can be searched alongside public sources, rubric based grading and commenting on reports, and template exclusion so shared boilerplate does not register as similarity. Institutional deployments are web based with no installation and connect through Google Classroom, Moodle and Canvas, LTI 1.3 for other systems, OneRoster roster synchronization, a Google Docs add on and Zapier. Batch checking covers Canvas discussion boards, optional two factor authentication is available, and the vendor states 99.99% uptime. The service has been running since 2011 and serves schools, higher education, individual writers and business customers.
Institutional pricing is not listed. Both institutional tiers, Advanced and Pro, carry a request quote action, and the site directs organizations to a quote or a demo rather than publishing a figure. The two differ in scope: Advanced offers an interface in English, German, French, Portuguese or Spanish, while Pro adds any interface language, searching of closed depositories and libraries, integration with any other LMS and VIP support. Separate tracks exist for individuals and for platform and enterprise customers, with annual subscriptions offered alongside monthly ones for individuals, and a free check of two pages is available.
