In their own words
Plagium
Plagium analyzes text for similarity with other material and offers a separate tool for identifying patterns compatible with AI-generated writing. Its plagiarism service compares submitted text with an online database and reports similarities with links to original sources. The AI Detector uses statistical and probabilistic analysis of writing patterns. Deep Search accepts Microsoft Word, PDF, and native text files; Google Drive integration and a Google Docs add-on support document analysis. Institutional users can access an API, while business solutions can integrate with corporate CRM, ERP, and document-management systems. Plagium presents solutions for educational institutions, publishers, editors, companies, researchers, and compliance teams. The free account costs nothing and allows five daily searches with a 4,000-character limit, but excludes Deep Search and API access. Plagium says submitted content remains owned by the user and is processed for analysis, report generation, and service improvement. Reports are automated estimates rather than definitive proof, and private, unpublished, or non-indexed material may not be detected.
