If the text feels a bit too perfect, this is a sign that it could have been written by an AI model.<\/li>\n<li><strong>Repetitive Phrasing<\/strong> \u2013 AI tools often reuse the same odd sentence structures and phrases. This leads to predictable writing patterns that sound a bit mechanical.<\/li>\n<li><strong>Vague or Generic Explanations<\/strong> \u2013 Instead of offering deep research or specific details, AI writing tends to explain concepts broadly without providing examples.<\/li>\n<li><strong>Excessive Use of Connectors<\/strong> \u2013 Words like \u201cadditionally\u201d, \u201cmoreover\u201d, and \u201cin conclusion\u201d tend to show up frequently in AI phrases. Models use these connectors to maintain the flow, but they often overdo it.<\/li>\n<li><strong>Lack of Context or Nuance<\/strong> \u2013 Human writers can weave in context, personal anecdotes, and golden nuggets of insight, but AI struggles to replicate this level of depth.<\/li>\n<\/ol>\n<h2><strong>How to Detect AI Content In Google Sheets<\/strong><\/h2>\n<p><picture><source srcset=\"https:\/\/undetectable.ai/blog\/wp-content\/uploads\/2026\/08\/ffffff-22-1024x683-1.avif \"  type=\"image\/avif\"><source srcset=\"https:\/\/undetectable.ai/blog\/wp-content\/uploads\/2026\/08\/ffffff-22-1024x683-1.webp \"  type=\"image\/webp\"><img src=\"https:\/\/undetectable.ai/blog\/wp-content\/uploads\/2026\/08\/ffffff-22-1024x683-1.webp\" class=\" sp-no-webp\" alt=\"Spreadsheet document information financial startup concept snugly\" decoding=\"async\"  > <\/picture><\/p>\n<p>If you frequently create content in Google Sheets, there are two different ways you can detect AI-generated content.<\/p>\n<p>The first method is to <strong>review the content yourself manually<\/strong>.<\/p>\n<p><!-- inline-cta --><\/p>\n<p>This involves reading each passage line by line, looking for potential AI patterns, and flagging words and phrases that feel off.<\/p>\n<p>The other option is to use an <strong>AI detection tool<\/strong> (like our own Undetectable <a href=\"https:\/\/undetectable.ai\/ai-detector\" target=\"_blank\" rel=\"noopener\">AI Detector<\/a>) to flag AI content automatically.<\/p>\n<p>These tools can scan large blocks of text in seconds, highlighting areas that are most likely to be AI-generated.<\/p>\n<p>Neither method is necessarily better than the other. Instead, the best AI content reviewers and editors tend to use both.<\/p>\n<p>This allows them to review large amounts of content efficiently, while still being able to catch the subtle nuances that only a human eye can spot.<\/p>\n<h2><strong>Manual Methods to Detect AI Content in Google Sheets<\/strong><\/h2>\n<p>To start verifying AI-generated content manually in Google Sheets, all you need is a sharp eye and an organized spreadsheet.<\/p>\n<h3><strong>Pattern Recognition by Human Review<\/strong><\/h3>\n<p>Once you\u2019re familiar with the patterns of AI-generated content, it\u2019s easy to spot it yourself in the written material you\u2019re reviewing.<\/p>\n<p>Manual reviewing takes some effort (especially if you\u2019re reviewing a large amount of text in one go), but Google Sheets makes it easier to organize and flag suspicious AI text.<\/p>\n<p>Here\u2019s a step-by-step approach for flagging and fixing AI content.<\/p>\n<p><!-- html-block --><\/p>\n<div class=\"blog-wp-table\">\n<table class=\"has-fixed-layout\">\n<tbody>\n<tr>\n<td class=\"has-text-align-center\" data-align=\"center\" colspan=\"2\"><strong>How to Detect AI-Generated Content in Academic Writing and Online Content Using Google Sheets<\/strong><\/td>\n<\/tr>\n<tr>\n<td class=\"has-text-align-center\" data-align=\"center\"><strong>Step 1: Create a Review Column<\/strong><\/td>\n<td class=\"has-text-align-center\" data-align=\"center\">Start by copying your text samples into one column. <\/p>\n<p>Then, add a second column where you can note any suspicious patterns, such as repeated phrases, overly formal tone, and vague statements.<\/td>\n<\/tr>\n<tr>\n<td class=\"has-text-align-center\" data-align=\"center\"><strong>Step 2: Use Filters to check for Repetition<\/strong><\/td>\n<td class=\"has-text-align-center\" data-align=\"center\">Repeated words and phrases are an obvious giveaway of AI text.<\/p>\n<p>Use functions like &#8220;COUNTIF&#8221; to detect words and phrases that occur multiple times throughout batches of text. <\/p>\n<p>For example, if phrases like &#8220;in conclusion&#8221; or &#8220;it&#8217;s not just&#8230;&#8221; keep showing up over and over, that&#8217;s a red flag for AI writing.<\/td>\n<\/tr>\n<tr>\n<td class=\"has-text-align-center\" data-align=\"center\"><strong>Step 3: Color-Code for Readability<\/strong><\/td>\n<td class=\"has-text-align-center\" data-align=\"center\">Patterns can sometimes be easier to spot if they&#8217;re color-coded. <\/p>\n<p>Use Google Sheets&#8217; conditional formatting to highlight phrases that repeat, look too generic, or feel overly polished.<\/p>\n<p>For example, you could automatically color-code any phrase that contains connectors like &#8220;moreover&#8221; and then edit as needed.<\/td>\n<\/tr>\n<tr>\n<td class=\"has-text-align-center\" data-align=\"center\"><strong>Step 4: Edit<\/strong><\/td>\n<td class=\"has-text-align-center\" data-align=\"center\">Once you&#8217;ve flagged everything that feels like AI, you can then edit the content directly in Google Sheets or flag it for further review.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p><!-- \/html-block --><\/p>\n<h3><strong>Limitations of Manual Review<\/strong><\/h3>\n<p>This method works best when you\u2019re dealing with small amounts of text. However, it\u2019s not very practical for longer passages.<\/p>\n<p>It\u2019s also worth mentioning that humans are inherently biased, so words that sound \u201crobotic\u201d to one person may seem fine to another.<\/p>\n<p>Without standardized checks, two reviewers might respond differently to the same passage, leading to inconsistent evaluations, mistakes, and <em>very<\/em> frustrated writers.<\/p>\n<h2><strong>Connecting External AI Detection Tools to Google Sheets<\/strong><\/h2>\n<p>Manual reviews are still essential for the editing process.

<\/picture><\/p>\n<p>Undetectable AI is just one of many other AI tools out there that can help you flag AI text.<\/p>\n<p>However, even though these tools <em>claim<\/em> they can accurately spot AI-generated content, what you might not know is that most detectors struggle to spot AI text <em>consistently<\/em>.<\/p>\n<h3><strong>ZDNet Study on Detection Accuracy<\/strong><\/h3>\n<p>This was

study<\/a> that compared popular AI content detectors.<\/p>\n<p>After testing 11 different tools, ZDNet discovered that accuracy rates vary widely across different AI checkers.<\/p>\n<p>Although Undetectable AI was one of five tools with 100% accuracy, other AI detection tools failed to correctly identify AI-written text.<\/p>\n<p>Not only that, but they also frequently incorrectly flagged human-written text as AI.<\/p>\n<h3><strong>Why Undetectable AI Outperforms<\/strong><\/h3>\n<p>A lot of the AI content detectors out there are trained using training data that doesn\u2019t necessarily reflect all the different writing styles we see in the real world.<\/p>\n<p>As a result, these tools often misclassify polished human-generated content as AI-generated.<\/p>\n<p>In contrast, the more advanced machine learning models (like <a href=\"https:\/\/undetectable.ai\/\" target=\"_blank\" rel=\"noopener\">Undetectable AI<\/a>) are trained on more diverse datasets and use more advanced natural language processing.<\/p>\n<p>This helps minimize the risk of false positives, and it\u2019s why some tools are more accurate than others.<\/p>\n<p>However, if you\u2019ve ever
