This text appears to be a mix of AI and human generation.

Burstiness Score: 0/100

Burstiness measures the variation in your sentence lengths. Humans tend to write with high burstiness (mixing very short and very long sentences), while AI writes with more uniform sentence lengths.

Perplexity Score: 0/100

Perplexity measures how predictable the words are. AI models choose highly predictable words (low perplexity). Humans often use creative, less predictable word choices (high perplexity).

Sentence Analysis

Highlighted sentences exhibit predictable patterns commonly generated by AI.

Understanding AI Content Detection

As artificial intelligence models like ChatGPT, Gemini, and Claude become more integrated into our writing processes, the ability to distinguish between human and machine-generated text is more important than ever. Our AI Content Detector uses advanced linguistic analysis to provide an objective score on the origin of your content.

How Our AI Detector Works

Unlike simple keyword checkers, our tool looks at the underlying structure of the language. We focus on two primary metrics that are characteristic of human writing vs. AI generation:

  • Perplexity: This measures how "surprising" the word choices are. AI models are trained to pick the most statistically probable next word, resulting in low perplexity. Humans, however, are creative and unpredictable, resulting in higher perplexity scores.
  • Burstiness: This refers to the variation in sentence structure and length. AI tends to produce sentences of similar length and complexity. Humans naturally vary their pace, mixing short, punchy sentences with longer, complex ones.

How to Use the Detector

  1. Copy the text you wish to analyze (minimum 20 words for accuracy).
  2. Paste the content into the text area above.
  3. Click the Detect AI button.
  4. Review the probability score and check the highlighted sentences to see which parts of your text triggered the detection.

Why Detect AI Content?

Content creators, educators, and SEO professionals use AI detection to ensure authenticity. For students, it's about maintaining academic integrity. For publishers, it's about ensuring their writers are producing original work. In the world of SEO, search engines prioritize unique, human-centric content that provides genuine value.

Accuracy Tips:

  • Use at least 250 characters for better results.
  • Purely technical manuals may flag as AI due to their formal structure.
  • Detection is a probability, not a definitive proof.

Frequently Asked Questions

Yes, our detector analyzes linguistic patterns that are common across almost all Large Language Models (LLMs), including the latest versions of ChatGPT, Gemini, Claude, and Llama.

Not necessarily. A high AI score simply indicates that the text has a linguistic structure similar to machine-generated content. Highly technical or very formal human writing can sometimes produce these patterns.

No. Our analysis is performed privately. We do not use your submitted text to train models or share it with third-party AI developers.
