AI Detector to Distinguish Between Human and AI-Generated Text
Detect AI-written, AI-paraphrased, and human text in seconds. Use this reliable AI checker to get sentence-level analysis with clear explanations — all for free.
How to use the AI Detector
Our AI detection tool applies sophisticated analysis to find AI content in your text. Here is how to detect AI writing in four simple steps. The process is fast, safe, and requires no account or sign-up.
Paste your text
Copy and paste the content you want to analyze into the AI checker free tool above. The tool accepts up to 12,000 characters per scan, giving you a thorough analysis of your content.
Let AI analyze it
DetectMy uses advanced language models to distinguish AI writing patterns from human ones. The system examines sentence structure, vocabulary choices, and stylistic consistency to detect AI content with high accuracy.
See explanations
Every sentence is individually classified as human-written, AI-generated, or AI-paraphrased. This granular approach helps you spot AI at the sentence level so that you know exactly which parts need more attention.
Get actionable results
You receive an overall AI likelihood score plus color-coded highlights showing where DetectMy flagged AI content. The results are transparent, easy to understand, and aimed at helping you make substantiated decisions about your content.
How to interpret the results
Don't overthink it. Our AI checker provides three separate categories so you can quickly interpret the analysis and take action.
Human-written content
Sentences categorized as human-written show signals of human authorship. These include personal voice, natural variation in sentence structure, unique perspectives, and the kind of creative expression that comes from genuine human thought. When the AI detector flags content as human-written, it means the language patterns are consistent with natural human writing rather than machine-generated text. This does not mean the content is perfect — human writing often contains minor imperfections, which is one of the signals DetectMy system looks for.
AI-generated content
When the AI check tool identifies content as AI-generated, it has found patterns typical of text produced entirely by AI writing tools like ChatGPT, Claude, Gemini, or similar models. Common indicators include formulaic sentence structures, overly balanced viewpoints, generic examples, and a consistency of tone that rarely occurs in natural human writing. Unlike a haphazardly made ChatGPT checker, our tool includes a confidence score that tells you how certain it is about this classification. A high score simply means the writing patterns strongly resemble AI-generated output.
AI-paraphrased content
AI-paraphrased content sits between fully human and fully AI-generated text. This category indicates that the original ideas may have been human-authored, but the text has been processed through an AI tool for rewording, polishing, or restructuring. DetectMy identifies this through subtle markers: the ideas feel original, but the expression feels smoothed out, unnaturally consistent in quality, or lacking the natural rhythm of human prose. This is one of the hardest categories to detect AI content accurately, and our system provides confidence scores to help you understand the result.
About confidence scores
Every analysis includes an overall AI score from 0 to 100 percent. A score closer to 0 suggests the text is predominantly human-written. A score closer to 100 suggests it is predominantly AI-generated. Scores in the middle range indicate mixed content or content where the AI detection system has lower certainty. No AI detection tool is 100 percent accurate, and results should be used as one data point among many when evaluating content authenticity. We encourage a responsible attitude and recommend against using any single score as the sole basis for important decisions.
Common use cases
From academic integrity to content publishing, the AI detector serves anyone who needs to understand the origins of written content. Here is how different people use DetectMy.
Students & academics
Students can use the tool to verify that their own writing reads as authentically human before submitting assignments. If you have used AI tools during your research or drafting process, running your final text through an AI content detector helps you understand how your work might be perceived. If you're a student, you can also use the tool as a revision check: flag sentences that sound generic and rewrite them. It is especially useful before high-stakes submissions like scholarship essays, personal statements, capstone reports, or group projects.
Educators & institutions
Teachers, professors, and educational institutions can use the AI detector as one component of their academic integrity strategy. When you need to detect AI writing, this tool provides sentence-level analysis that helps facilitate productive conversations with students about their writing process. Rather than serving as a punitive tool or a strict originality checker, DetectMy can open dialogue about what constitutes appropriate use of AI writing assistance. The detailed breakdown helps educators understand which passages may warrant further discussion.
Publishers & content teams
Content publishers, editorial teams, and media organizations need to maintain trust with their audiences and can't afford to appear questionable. The AI checker helps editorial workflows by flagging content that may need additional review. Whether you are vetting freelance submissions, auditing existing content, or establishing AI content policies, the ability to detect AI writing at the sentence level gives your team actionable insights. DetectMy integrates naturally into existing editorial workflows without disrupting your publishing schedule.
Businesses & professionals
Marketing teams, HR departments, and business professionals can use the AI content detector to ensure their communications win their audience's trust and loyalty, too. As AI writing tools become ubiquitous, the ability to identify AI writing in proposals, reports, and marketing copy helps maintain brand authenticity. Professionals can also use the AI detector to refine AI-assisted drafts, iterating until the content genuinely reflects their expertise and perspective. It is also handy for quality control across teams, so a campaign, email sequence, or internal policy reads like one coherent brand voice.
