Copyleaks Key Insights
What is Copyleaks?

Copyleaks is an AI powered content integrity platform that helps businesses, educators, and individuals verify the authenticity of written content. Founded in 2015, it combines advanced AI content detection with plagiarism checking to identify text generated by models like ChatGPT, Gemini, and Claude.
The platform scans for AI generated content in over 30 languages and checks for plagiarism across 100+ languages, making it one of the most versatile content verification tools available today. Copyleaks serves a wide range of users, from universities enforcing academic integrity policies to enterprise teams managing content governance and IP protection. With LMS integrations, a flexible API, and browser extensions, it fits directly into existing workflows.

Copyleaks uses proprietary algorithms to detect AI generated text from all major large language models including ChatGPT, GPT 5, Gemini, DeepSeek, and Claude. Multiple independent third party studies have confirmed it as the most accurate AI detector on the market. It identifies AI patterns at both sentence and document level, giving users granular insight into which portions of a text were likely machine generated.

The plagiarism checker scans content against billions of web pages, academic journals, and a shared database of user submitted documents. It supports over 100 languages and can detect cross language plagiarism, meaning it catches content that has been translated from one language to another to avoid detection. This is especially valuable for global organisations managing content across multiple regions.
AI Logic is a standout feature that merges AI detection and plagiarism results into a single unified report. Instead of running two separate scans, users get a complete picture of content authenticity in one view. This saves time and provides clearer context for decision making in both academic and business settings.

Copyleaks extends beyond text with its CodeLeaks feature, which scans programming code for similarities. It supports languages like Python, Java, and C++ and provides side by side comparison reports. This makes it a valuable tool for computer science educators and software development teams protecting proprietary code.

The platform integrates directly with major learning management systems including Moodle, Canvas, and Blackboard. For enterprise users, the Copyleaks API offers full customisation with bearer token authentication, private cloud storage options, and scalable scan volumes. This flexibility makes it suitable for organisations of any size.
Users can scan content for AI and plagiarism without leaving their browser or document editor. The Chrome extension works on any web page, while the Google Docs add on allows scanning within the writing environment. Both tools make it simple to check content as part of a daily workflow.chromewebstore.
