Plagius

What Plagius is

Plagius analyzes academic papers and other documents for possible plagiarism by checking the internet or local files. Its desktop software supports Word, PDF, OpenOffice, PowerPoint, HTML, RTF, and plain-text files. Reports identify suspicious phrases and sources, show URLs with similarity percentages, estimate suspected-plagiarism percentages, and provide analysis quality indicators. Results can be viewed in a browser or exported as HTML. The V5 AI detector evaluates paragraphs in context and gives an AI-generation probability with a confidence level; the site says it recognizes signals from more than 15 models, including Gemini 3.7, GPT 5.6, and Claude 5. Professional desktop plans add local searches across computer files or network shares, batch analysis, direct URL checks, and comparisons between files. The maker says desktop analysis runs locally without sending the full document to its servers. External search engines may receive text fragments, usually 7 to 13 words; AI detection may send isolated paragraphs to Plagius servers, where excerpts are deleted within up to 48 hours. Plagius One is browser-based and initially limited to invited users. Plagius Basic costs $6.90 per once, with a 30-day license for one Windows computer and no AI detection.
