Undetectable AI was developed by Bars Juhasz, a PhD student from Loughborough University, along with Christian Perry,[4][5] and Devan Leos. It was publicly released in May 2023.[6][7][8]
In July 2023, researchers from Magna Græcia University tested Undetectable.ai against generative-text and plagiarism detection software. They found that texts processed through Undetectable.ai were significantly harder to detect as AI-generated.[11]
In November 2023, Erik Piller of Nicholls State University published a paper examining ethical implications of Undetectable AI in professional writing contexts.[12][13]
In August 2023, researchers led by Dr. Christoph Bartneck investigated how Undetectable.ai might affect data quality in online questionnaires. They found that while AI detection systems could identify ChatGPT-generated text, they were less successful with text processed by Undetectable.ai.[14]
A research paper was also published in 2024 by Kar et. al, who tested the accuracy of various online AI detection models which included Undetectable AI.[15]
Usage and impact
In November 2023, EarthWeb used Undetectable.ai alongside GPTZero to analyze online apology statements.[16][10]
A January 2024 report listed Undetectable AI as the 35th most visited AI software in 2023 out of 150 analyzed.[17] In February 2025, Journalist David Gewirtz tested Undetectable AI's content detector to see if it could accurately identify AI-generated text.[18]
Last month, journalist Matthew Giannelis published a piece titled "Undetectable AI Becomes The New Challenge In Artificial Content Detection,"[19] which documents how prevalent Undetectable AI tools have become, and the off-shoots (or copy cat startups), as well as concerns about synthetic content becoming too indistinguishable from human work.
