How Plag protects academic integrity
Text similarity check
Plag checks text potential plagiarism against a database of more than 500 million scholarly articles and web pages, identifying text similarity and potential source matches across 129 languages.
AI-Generated Content Detection
Plag also offers a dedicated AI-generated text detection mode, which determines whether content is likely written by a human or produced using a generative AI tool. This function is available in 50+ languages.
Cross-language translated plagiarism
Plag supports translated plagiarism detection, flagging cross-language similarity and original source matches even when content has been translated from/to over 50 languages.
Why We're Making Our Services Free
Too many educators face an impossible choice: pay out of pocket for plagiarism detection tools, or go without them entirely. This creates inconsistencies in how academic work is evaluated and puts financial strain on teachers who are already underpaid.
We believe maintaining high academic standards shouldn't depend on personal budgets or institutional resources. Every educator deserves professional-grade tools to uphold academic integrity.
