# Copyleaks

Copyleaks is a plagiarism detection platform that uses artificial intelligence (AI) to identify similar and identical content across various formats.
Copyleaks was founded in 2015 by Alon Yamin and Yehonatan Bitton, software developers working with text analysis, AI, machine learning, and other cutting-edge technologies.
Copyleaks' product suite is used by businesses, educational institutions, and individuals to identify potential plagiarism and AI-generated content in order to provide transparency around responsible AI adoption.
In 2022, Copyleaks raised $7.75 million to expand its anti-plagiarism capabilities.

## Functionality

Copyleaks is used in academia to detect plagiarism, paraphrasing, and potential copyright violations. The release of AI models and rapid adoption has led to students increasingly using these tools to complete their work so Copyleaks helps to distinguish between content created by humans and content generated by AI.

### Plagiarism Detector

As generative AI becomes more commonplace, plagiarism is also a growing concern among schools, universities, and publishers.
Plagiarism Detector analyzes text to determine its authenticity and precision. Plagiarism Detector goes beyond the traditional method for determining plagiarism, which compares the text of a document word-by-word against a wide database of previously published articles and books. Instead, Copyleaks uses an AI model that comprehends the meaning of a document and even recognizes the writing style of its author so it is difficult for anyone to pass along plagiarized text as their own by simply changing a few words or phrases of a copied document.

### AI Detector

Copyleaks uses advanced AI to detect AI-generated content and can help mitigate the challenges of academic integrity. The tool can also highlight potentially paraphrased text to mask AI generation.
Copyleaks claims a higher than 99% accuracy rate of detecting AI-generated content from models like ChatGPT, Copilot, GitHub, and Bard across 30 languages with a 0.2% false positive rate. The AI Detector Chrome extension enables users to verify social media, news articles, review sites, Google documents, and other online content. In November 2023, a research team from the School of Education at the University of Adelaide found Copyleaks to be a reliable tool in an analysis of AI detection tools. Copyleaks determined there was an 85.2% probability for AI content for a movie critique of House of Flying Daggers written like a 14-year-old school student, and a 73.1% probability for AI content for the essay even after it had been altered by a human.

### Codeleaks

The Codeleaks Source Code AI Detector can identify AI-generated code from ChatGPT, Google, Gemini, and GitHub Copilot. The detector can spot if code has been plagiarized or modified and provides any key licensing details. Codeleaks looks at the semantic structures of code to determine whether it has been potentially paraphrased to determine its originality and integrity.

### Generative AI Governance and Compliance

Regulations are necessary to provide guardrails for AI use. Copyleaks can help enterprises create enterprise-wide policies to ensure safe and responsible AI use.

## Criticism

In June 2023, an international team of academics found AI detection tools inaccurate and unreliable. In an analysis of five AI content detection tools – Copyleaks, OpenAI, Writer, GPTZero, and CrossPlag – Copyleaks struggled with sensitivity, that is, the proportion of AI-generated content correctly identified by the detectors out of all AI-generated content. Copyleaks had the highest sensitivity at 93% for content generated by ChatGPT 4.
