Grok's AI response<\/a><\/rel><\/p>\n<p>The use of AI can lead to conflicts when someone claims to have written a text that was actually produced by artificial intelligence. <strong>There are various digital tools available to detect AI usage in a text<\/strong>, some of which are free. The issue when using them is: <strong>are these tools actually reliable?<\/strong><\/p>\n<p>I have been writing this blog for 22 years. <strong>I enjoy writing, and I don't want AI to take that pleasure away from me.<\/strong> I decided to test several of these verification tools using a text I wrote years ago\u2014specifically, <a href=\"https:\/\/www.outono.net\/elentir\/2018\/11\/11\/polonia-y-espana-los-vinculos-historicos-entre-dos-grandes-naciones-de-europa\/\">an article from November 2018 about Spain and Poland<\/a>. When I wrote it nearly eight years ago, the AI \u200b\u200btext-generation tools we have today did not exist (or, if they did, they certainly weren't available to the general public). <strong>You can verify the text's publication date, as<\/strong> <a href=\"https:\/\/web.archive.org\/web\/20181111124309\/https:\/\/www.outono.net\/elentir\/2018\/11\/11\/polonia-y-espana-los-vinculos-historicos-entre-dos-grandes-naciones-de-europa\/\" target=\"_blank\">it was archived on the Wayback Machine in 2018<\/a>. If I had made any changes, they would be visible there.<\/p>\n<p>Since not all verification tools can process large amounts of text, <strong>I ran the check using the article's first three paragraphs<\/strong> (those appearing before the first photo embedded in the text). This amounts to a total of 2,187 characters. <strong>Here are the results I obtained from various verification websites:<\/strong><\/p>\n<ul>\n<li><a href=\"https:\/\/www.scribbr.com\/ai-detector\/\" target=\"_blank\">Scribbr.com<\/a>: 100% human written, 0% AI.<\/li>\n<li><a href=\"https:\/\/gptzero.me\/es\" target=\"_blank\">GPTZero.me<\/a>: 100% human, 0% AI.<\/li>\n<li><a href=\"https:\/\/quillbot.com\/es\/\" target=\"_blank\">Quillbot.com<\/a>: 100% written by people, 0% AI.<\/li>\n<li><a href=\"https:\/\/originality.ai\/es\" target=\"_blank\">Originality.ai<\/a>: likely original: 100% confidence.<\/li>\n<li><a href=\"https:\/\/copyleaks.com\/es\/ai-detector\" target=\"_blank\">Copyleaks<\/a>: 0% AI.<\/li>\n<li><a href=\"https:\/\/www.zerogpt.com\/\" target=\"_blank\">ZeroGPT<\/a>: 36.8% written by an AI.<\/li>\n<li><a href=\"https:\/\/justdone.com\/es\/ai-detector\" target=\"_blank\">Justdone.com<\/a>: 92% AI content, 8% Text written by humans.<\/li>\n<li><a href=\"https:\/\/humalingo.com\/ai-detector\" target=\"_blank\">Humalingo.com<\/a>: 96% AI, 4% human.<\/li>\n<\/ul>\n<p><strong>It is interesting to find such disparate results.<\/strong> While some identified the text as 100% human-written (which is correct, and I can vouch for that), other checkers seemed to think it was almost entirely written by AI, when that is not the case. <strong>In any event, this test helps me determine which checkers to use should the need arise<\/strong>, but above all, it shows that AI\u2014since those tools ultimately run on artificial intelligence\u2014is not as infallible as many people believe.<\/p>\n<p>---<\/p>\n<p><small>Image: Meta.ai.<\/small><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Artificial intelligence (AI) is increasingly being used as a tool for writing texts, for a wide variety of purposes.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":"","_links_to":"","_links_to_target":""},"categories":[15961,20879],"tags":[18485],"class_list":["post-67570","post","type-post","status-publish","format-standard","hentry","category-bloque-6-english","category-technology","tag-artificial-intelligence"],"publishpress_future_action":{"enabled":false,"date":"2026-10-08 22:23:39","action":"change-status","newStatus":"draft","terms":[],"taxonomy":"category","extraData":[]},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"_links":{"self":[{"href":"https:\/\/www.outono.net\/elentir\/wp-json\/wp\/v2\/posts\/67570","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.outono.net\/elentir\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.outono.net\/elentir\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.outono.net\/elentir\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.outono.net\/elentir\/wp-json\/wp\/v2\/comments?post=67570"}],"version-history":[{"count":0,"href":"https:\/\/www.outono.net\/elentir\/wp-json\/wp\/v2\/posts\/67570\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.outono.net\/elentir\/wp-json\/wp\/v2\/media?parent=67570"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.outono.net\/elentir\/wp-json\/wp\/v2\/categories?post=67570"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.outono.net\/elentir\/wp-json\/wp\/v2\/tags?post=67570"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
