What Plag.ai is

Plag.ai is a web service for plagiarism checking, AI detection, and finding plagiarism across translated text. Its plagiarism checker looks for copied passages, incorrect references, and paraphrases, then highlights matching text and links to sources. It uses different highlight colors to distinguish proper quotations from citations flagged as plagiarism. The AI detector supports more than 50 languages, provides sentence-level breakdowns, and offers downloadable PDF reports. A separate translated-plagiarism check compares meaning across 56 languages to find cross-language matches. Plag.ai supports 129 languages overall.

The homepage offers up to three free evaluations: one each for plagiarism, AI detection, and translated plagiarism. Free document uploads include DOC, DOCX, and TXT; the site also accepts other formats, including Word, LibreOffice, Pages, and PowerPoint. Plag says documents are not stored or shared, including with institutions or third parties. Its tools are described for students, educators, schools, universities, publishers, and other professionals. Educators worldwide can use premium plagiarism and AI detection free, with unlimited uploads and no word or page limit. Monthly plans begin with Basic at €14.95 a month.
