AI detectors<\/strong><\/a> are tools designed to detect when a text was generated by an AI writing tool like ChatGPT. AI content may look convincingly human in some cases, but these tools aim to provide a way of checking for it. We’ve investigated just how accurate they really are.<\/p>\n

To do so, we used a selection of testing texts including fully ChatGPT-generated texts, mixed AI-and-human texts, fully human texts, and texts modified by paraphrasing tools. We ran all these texts through 10 different AI detectors to see how accurately each tool labeled them.<\/p>\n

Our research indicates that if you’re willing to pay, the most accurate AI detector available right now is Winston AI<\/strong>, which identified 84% of our texts correctly. If you don’t want to pay, Sapling<\/strong> is the best choice: it’s totally free and has 68% accuracy, the highest score among free tools.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

General conclusions<\/h2>\n

In general, our research showed that because of how AI detectors work<\/a>, they can never provide 100% accuracy. The companies behind some tools make strong claims about their reliability, but those claims are not supported by our testing. Only the premium tools we tested surpassed 70% accuracy; the best free tool, Sapling<\/a>, scored 68%.<\/p>\n
