“John Kohn Reliable and trustworthy . Originality is always so quick to respond to my questions and lend a helping hand. It’s a very good tool for detecting ChatGPT use on academic papers, especially with the "view writing" feature which shows the text being typed by the student as they were typing it.”
“Gael Breton Founder, Authority Hacker So what can we learn from this? In many cases, the tool tells the right story, even when it's nuanced, like in the case of AI content edited by humans.”
“Glenn Gabe SEO Consultant, GSQI.com After testing a number of AI content detection tools, I have found Originality.ai to be one of the best on the market . And now with the ability to detect paraphrased AI content, Orignality.ai is even more powerful. It’s basically my go-to detection tool at this point.”
