This is an estimate of AI generation likelihood based on structural patterns.
Estimate the likelihood of AI generation by analyzing writing patterns, burstiness, and lexical perplexity.
Artificial Intelligence content generators (like ChatGPT, Claude, and Gemini) generate text by predicting the next most likely word in a sequence. While this results in grammatically correct copy, it also leaves distinct statistical patterns. Our advanced local **AI Content Detector** analyzes these patterns to estimate the likelihood that a text was written by an AI.
Rather than using arbitrary guessing, the engine calculates structural and mathematical properties of your writing, primarily focusing on sentence length distribution, vocabulary diversity, and highly predictable word pairings.
To give you a precise breakdown of your text's composition, the detector evaluates four key parameters:
| Metric | Human Writing Characteristics | AI Writing Characteristics |
|---|---|---|
| Burstiness | High variation in sentence structures. Humans write short sentences followed by long complex ones. | Low variation. AI models tend to produce uniform, equal-length sentences. |
| Perplexity | High perplexity. Humans use creative vocabulary, metaphors, and unpredictable phrasing. | Low perplexity. AI uses highly predictable words that have high probability scores in the model. |
| Readability | Varies widely based on target audience, styling, and personal author voice. | Averages around 40-60 (standard high-school or early college level writing). |
| AI Clichés | Minimal use of cliché transition terms unless necessary for formal context. | Frequent use of over-represented words (e.g., 'delve', 'testament', 'moreover'). |
If your draft returns a high AI likelihood score, you can humanize it by editing the structural patterns that the detector looks for:
Most online AI detection websites require you to paste your copy and submit it to their backend servers. This poses severe data privacy risks, especially when checking corporate reports, unpublished drafts, academic research papers, or personal blogs.
Our **AI Content Detector** operates 100% locally. The analysis engine runs completely client-side in your browser's memory, ensuring that your text is never uploaded to a database or shared over the internet.
An AI Content Detector is a tool that analyzes writing patterns, word distribution, and structural rhythm to predict whether a block of text was generated by a machine learning model (like GPT) or a human author.
Yes. It is 100% free with no registration requirements, no daily usage limits, and no hidden subscriptions. You can check as much text as you need.
Perplexity measures the unpredictability of vocabulary. Humans write with high perplexity (unusual word choices), while AI uses predictable high-probability words. Burstiness measures sentence length variance. Humans write with high burstiness (mixing long and short sentences), while AI writes with low burstiness (uniform sentence structures).
No. Your privacy is protected because our tool operates entirely client-side. The mathematical calculations run inside your browser's sandbox memory, and no data is sent to external web servers.
To bypass detection, rewrite sentences to vary their lengths, choose less predictable transition words, use active voice verbs, and use our free **AI Humanizer** tool to automatically polish structural patterns.
