Server-poweredDetect whether text is AI-generated or human-written online. Free AI content detector using analysis and statistical metrics.
About the AI Content Detector
The AI Content Detector is a powerful tool that combines AI-powered analysis with statistical metrics to determine whether text was written by a human or generated by AI. It evaluates six key dimensions: perplexity, burstiness, vocabulary richness, structural patterns, voice and personality, and repetition patterns.
Unlike simple heuristic detectors, this tool uses advanced AI to understand the nuances of writing style, identifying subtle patterns that distinguish human and AI-generated content. The analysis examines word choice predictability, sentence rhythm variation, use of informal language, structural formulas, personal voice, and semantic repetition.
As large language models like ChatGPT, Claude, and Gemini become more widely used, the ability to distinguish AI-written text from human-written text has become essential for educators, editors, publishers, and content creators.
Features
AI-Powered Analysis
Uses advanced AI to analyze writing patterns, style, voice, and structural cues that distinguish human from AI-generated content.
6 Detection Metrics
Evaluates perplexity, burstiness, vocabulary richness, structural patterns, voice & personality, and repetition coherence.
Flagged Phrases
Highlights specific phrases and patterns in your text that are commonly associated with AI-generated writing.
Detailed Scoring
Each metric is scored 0-100 with visual progress bars, assessments, and an overall human score with confidence level.
Actionable Insights
Provides analysis notes explaining what makes the text appear human or AI-written, with specific observations.
Statistical Supplements
Shows text statistics including word count, sentence variation, vocabulary diversity, and readability metrics.
How It Works
Submit Your Text
Paste the text you want to analyze. For best results, use at least 100 words. Longer texts provide more reliable analysis.
AI Deep Analysis
Your text is sent to our AI engine which performs a comprehensive multi-dimensional analysis examining word choice, sentence patterns, structural cues, and writing voice.
Statistical Computation
Simultaneously, local statistical metrics are computed: word count, sentence variation, vocabulary diversity, and readability indicators.
Multi-Metric Scoring
Six independent metrics are scored 0-100: Perplexity, Burstiness, Vocabulary & Style, Structural Patterns, Voice & Personality, and Repetition & Coherence.
Verdict & Report
Results are combined into a clear verdict (Likely Human, Mixed, or Likely AI) with confidence level, flagged phrases, and actionable analysis notes.
Frequently Asked Questions
How accurate is this AI content detector?
This tool combines AI-powered analysis with statistical metrics for high accuracy. However, no detector is 100% reliable. Accuracy improves with longer texts (200+ words). Results should be used as one data point alongside other assessment methods.
What metrics does it analyze?
Six dimensions: Perplexity (word predictability), Burstiness (sentence length variation), Vocabulary & Style (word diversity and register), Structural Patterns (formulaic constructions), Voice & Personality (human touch), and Repetition & Coherence (semantic patterns).
What is burstiness?
Burstiness measures the variation in sentence lengths. Humans naturally write with a mix of very short and long sentences (high burstiness). AI models tend to produce sentences of more uniform length (low burstiness).
Can AI-generated text be modified to bypass detection?
Heavily edited AI text or text generated with specific prompts to mimic human patterns can be harder to detect. However, the multi-dimensional analysis makes evasion more difficult than with simple heuristic detectors.
Is my text stored?
Your text is sent to our AI backend for analysis but is not stored, logged, or used for any other purpose. Statistical metrics are computed locally in your browser.
How many words do I need?
Minimum 50 words, but 200+ words is recommended for reliable results. Short texts don't provide enough signal for meaningful multi-dimensional analysis.
Does this detect specific AI models?
The tool detects general patterns common to AI-generated text. While it cannot identify the specific model (ChatGPT, Claude, Gemini, etc.), the patterns it detects are common across most large language models.
