(Of course, Google will undoubtedly have different tools and checks.)<\/p>\n<p><strong>Auditing AI usage<\/strong>: If you have a specific policy or way to compensate writers for original versus AI-generated content, these tools can give you a rough sense of whether a writer uses AI to generate content. (Note that they can also return false negatives and positives.)<\/p>\n<p><strong>Understanding search results:<\/strong> Some of these tools offer Chrome extensions, which can help you understand whether competitors and other websites use AI content or not.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_AI_detection_software_works\"><\/span>How AI detection software works<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Each tool is different and has its approach to the problem. But for the most part, ChatGPT detection tools grade content based on how predictable the phrase choices are within a piece of content.\u00a0<\/p>\n<p>In other words, the likelihood that content is scored as AI versus human has a lot to do with whether the detection software deems a piece of writing as following the likely pattern AI would follow in generating content.<\/p>\n<p>The two core concepts around this process are called:\u00a0<\/p>\n<p><strong>Burstiness<\/strong>: A predictable length and tempo to sentence structure.<\/p>\n<p><strong>Perplexity<\/strong>: A randomness to the words chosen in a sentence or collection of sentences.<\/p>\n<p>For example, in an essay about the founding of America, it\u2019s highly unlikely that generative AI would include a random, unevenly written anecdote about the first time they ever saw a penguin, so that would likely look like human writing to a detection tool.<\/p>\n<p>Similar to how ChatGPT detectors popped up to detect generative AI writing, tools are already being developed to get around the detectors. (And, of course: the detectors are likely already thinking about how to detect the bypassers, and so on).<\/p>\n<p>Tools like Undetectable or Quillbot will rewrite your content, sometimes making it more difficult to detect for certain AI detection tools.<\/p>\n<p>Additionally, several people have found different prompts to get ChatGPT and other AI writing tools to output content that scores \u201cmore human\u201d on the human-to-AI scale by using prompts defining burstiness and perplexity and telling ChatGPT to write with more of each.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Does_detection_accuracy_matter_to_you\"><\/span>Does detection accuracy matter to you?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>An important question to answer before you dive too far into these tools is:\u00a0<\/p>\n<p>How much do you care about detecting whether content is written by AI? And why?<\/p>\n<p>If you\u2019re using ChatGPT for rewriting title tags or generating email copy, maybe it doesn\u2019t matter at all if that content \u201cpasses\u201d AI writing checks.\u00a0<\/p>\n<p>Additionally, if a writer uses AI to generate a copy and the copy is great, maybe the score isn\u2019t important at all.<\/p>\n<p>These detection tools will likely be engaged in the \u201cdetection arms race\u201d with un-detection tools and prompts I mentioned above.<\/p>\n<p><!-- START INLINE FORM --><\/p>\n<div class=\"nl-inline-form border py-2 px-1 my-2\">\n<div class=\"row align-items-center\">\n<div class=\"col-12 col-lg-3 col-xl-4 pe-md-0 pb-2 pb-lg-0\">\n<p class=\"inline-form-text text-center mb-0\">Get the daily newsletter search marketers rely on.<\/p>\n<\/div>\n<div class=\"col-12 col-lg-7 col-xl-6  pe-lg-0\">\n<div class=\"form-nl-inline\">\n<div class=\"row g-0\">\n<div class=\"form-group col-12 col-lg-8 mb-0\"><\/div>\n<div class=\"col-12 col-lg-4 col-xl-4 mb-0\">\n<div class=\"d-none\">\n<p>Processing\u2026Please wait.<\/p>\n<\/div>\n<p>\t\t\t\t\t\t\t<button class=\"btn btn-dark inlineButton w-100 rounded-0 font-weight-bold\">SUBSCRIBE<\/button>\n\t\t\t\t\t\t<\/p><\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"col-12 col-lg-2 col-xl-2 ps-1\">\n<p class=\"text-center mb-0\"><a class=\"nl-terms\" href=\"https:\/\/searchengineland.com\/termsofuse\" target=\"_blank\" rel=\"noopener noreferrer\">See terms.<\/a><\/p>\n<\/div>\n<\/div>\n<\/div>\n<p><!-- END INLINE FORM --><\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_best_AI_writing_detectors_compared\"><\/span>The best AI writing detectors compared<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If you&#8217;re still looking for an AI\/ChatGPT content detector, we&#8217;ll go through each of them and how they \u201cscored\u201d in evaluating human-generated copy versus AI copy versus AI copy that used <a href=\"https:\/\/medium.datadriveninvestor.com\/the-ultimate-chatgpt-prompt-content-that-outsmarts-ai-detectors-with-99-accuracy-ef20d81582bb\" target=\"_blank\" rel=\"noopener noreferrer\">this prompt<\/a> to try to \u201cbeat detection.&#8221;<\/p>\n<p><strong>Note<\/strong>: Detection versus a few paragraphs of content isn&#8217;t necessarily a thorough test of the detection capabilities of these tools.

It also features a plagiarism scanner alongside the AI scanner.<\/p>\n<p>As you can see from the chart above, this is the only AI scanner with 100% confidence that the human content was human and that the AI content was AI (while also being correct in all cases).\u00a0<\/p>\n<p>Hive Moderation (discussed later in the article) essentially had the same conclusion with a 0% AI score for the human content and 99.9% confidence the two AI-generated texts were AI.<\/p>\n<p>On top of having a Chrome extension and an overall score, Originality.AI <a href=\"https:\/\/originality.ai\/highlight-ai-text\/\" target=\"_blank\" rel=\"noopener noreferrer\">added a feature<\/a> highlighting the specific sections of the content you paste that it predicts will and won\u2019t be AI. <\/p>\n<p>I use this tool most frequently to check for AI content personally. My most frequent use-case is checking content submitted by freelance writers we work with for AI and plagiarism.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Writer\"><\/span>2. Writer<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"wp-block-image\">\n<\/div>\n<p>Writer offers a free detector that works on up to 1,500 characters and requires API access for more.<\/p>\n<p>This tool essentially thought all of the submissions were relatively likely to be human-generated.\u00a0<\/p>\n<p>Writer is an AI writing platform, and the free content detector also allows you to input a URL to check.\u00a0<\/p>\n<p>There is no plagiarism feature within this tool directly, and it gives you an overall score but doesn\u2019t mark specific sections as likely or unlikely to be AI-generated.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Copyleaks_AI_Content_Detector\"><\/span>3.

However, it wasn&#8217;t always confident and was incorrect in some individual sections.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"4_OpenAIs_AI_Text_Classifier\"><\/span>4.

There aren&#8217;t a lot of bells and whistles and no plagiarism check.<\/p>\n<p>You get a finding (like what you see in the screenshot) but no precise score. It also won\u2019t highlight specific sections of copy for their individual likelihood of being AI-generated or not.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"5_Crossplag_AI_Content_Detector\"><\/span>5.

The tool does give an overall score but doesn&#8217;t offer the ability to check for plagiarism or mark up individual sections of the content.<\/p>\n<p>Crossplaq identified the human and AI content as 99% human. It is worth noting that the tool repeatedly calls out that it performs better on longer text. <\/p>\n<p>Our samples here were above their 200-character minimum recommendation but on the shorter side.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"6_GPTZero\"><\/span>6. GPTZero<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"wp-block-image\">\n<\/div>\n<p>GPTZero has free and paid versions. The free version gives you a score and has some pre-loaded examples.\u00a0<\/p>\n<p>The paid version also offers a plagiarism checker, highlighting AI content, and the ability to bulk upload multiple pieces of content (which is actually designed for a classroom environment, like many of these tools).<\/p>\n<p>Pricing for the paid tools isn&#8217;t listed on the website, but you can fill out forms to request access to the paid tool and the API.<\/p>\n<p>The free version of the tool identified all three of our writing samples as likely entirely human.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"7_Sapling_AI_Detector\"><\/span>7.

There is no plagiarism feature set here. <\/p>\n<p>The tool returned the highest number of \u201clikely words\u201d and particularly likely words in the top 10 for the text generated by the simpler prompt. <\/p>\n<p>Still, the distribution was similar for the human and additional prompt copy in this small test.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"11_ChatGPT_Detector_on_Hugging_Face\"><\/span>11.

Different tools will likely be \u201charder\u201d or \u201csofter\u201d graders when it comes to scoring content human versus AI, so understanding how a tool is calibrated can help determine how useful they are.<\/p>\n<p><strong>Rarest features<\/strong>: A few rare features across the tools were things like bulk uploads, plagiarism detection, having a Chrome extension, and highlighting specific sections with likelihood of being AI versus human.\u00a0<\/p>\n<p><strong>Free vs. paid<\/strong>: All of the tools featured here but Originality.AI had at least free versions. But the tools with the most accurate results and most \u201crare features\u201d tended to be the tools with a paid version.<\/p>\n<p>I\u2019d recommend keeping an eye on at least a few of these tools if you find AI detection useful in your projects.<\/p>\n<p>The pace of innovation across AI content generation, editing and detection may quickly make your favorite tool obsolete.<\/p>\n<p>The post <a href=\"https:\/\/searchengineland.com\/ai-chatgpt-content-detectors-395957\" target=\"_blank\" rel=\"noopener\">16 of the best AI and ChatGPT content detectors compared<\/a> appeared first on <a href=\"https:\/\/searchengineland.com\/\" target=\"_blank\" rel=\"noopener\">Search Engine Land<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"<p>As new ChatGPT alternatives pop up daily, AI content detectors are also gaining popularity.
