Third-Party Studies Continue to Confirm Copyleaks AI Detector as the Most Accurate

In This Blog

Key Takeaways

  • Most Accurate Detector: Independent studies show that Copyleaks’ AI Detector is one of the most accurate for detecting Large Language Models (LLMs).
  • International Studies: Third-party international studies confirm Copyleaks’ accuracy in detecting AI-generated content.
  • Machine Learning: Copyleaks provides in-depth AI detection, and machine learning allows it to evolve alongside AI technology to ensure the most up-to-date results.
  • Reliable Solution: Copyleaks is a reliable solution that effectively detects AI-generated text and adapts to technological advancements.

In July 2023, four researchers from across the globe published a study on the Cornell Tech-owned arXiv, declaring Copyleaks AI Detector the most accurate for detecting Large Language Models (LLM) generated text. 

For the study, the researchers collected 124 submissions from computer science students written before ChatGPT was created. They then generated 40 ChatGPT submissions and used the data to evaluate eight publicly available LLM-generated text detectors. 

Here were their key findings,

That was just the beginning. 

Since then, additional independent third-party studies have been released, each one highlighting the accuracy and efficiency of the AI Detector.

Check out the findings below.

Study: Accuracy Pecking Order – How 30 AI detectors stack up in detecting generative artificial intelligence content in university English L1 and English L2 student essays

Author: Chaka Chaka, University of South Africa

Published: April 2024

Only two AI detectors, Copyleaks and Undetectable AI, managed to correctly detect all of the essay sets of the two English language categories (English L1 and English L2) as human written. As a result, these two AI detectors jointly shared the first spot in terms of the GenAI detection accuracy ranking.

Taking a look at the Copyleaks AI detector on Swedish, it shows of a sensitivity of 100% as it is never wrongfully classifying any of the articles written by humans.

...the English part of the main study, the performance of the Smodin AI detector is good with high values of accuracy, sensitivity, and specificity. However, the performance of the Smodin AI detector is beaten by the Copyleaks AI detector on English, since the latter shows a constant 100% performance on all three of accuracy, sensitivity, and specificity.
