AI Content Detector
Analyze text to determine if it was written by AI or human using advanced pattern analysis
How AI Content Detection Works
Our AI content detector uses advanced heuristic analysis to identify AI-generated text by examining multiple linguistic and structural characteristics. The tool analyzes text patterns, word usage, and writing style to determine the likelihood that content was created by artificial intelligence models like ChatGPT, GPT-4, Claude, or Gemini.
The detection algorithm evaluates five key factors that distinguish AI writing from human writing:
- Perplexity Analysis: Measures word predictability and vocabulary diversity. AI-generated text often shows lower perplexity with more repetitive word choices and predictable language patterns compared to human writing.
- Burstiness Measurement: Analyzes sentence length variation and structural diversity. Human writers naturally vary sentence length and structure, while AI models tend to produce more uniform sentence patterns.
- Pattern Recognition: Identifies common AI writing patterns including excessive use of transition words, passive voice constructions, and repetitive structural elements that are characteristic of AI-generated content.
- N-gram Analysis: Examines word sequence patterns and phrase repetition. AI models often reuse similar word combinations and phrases, which can be detected through bigram and trigram frequency analysis.
- Stylometric Features: Evaluates writing style characteristics such as word length distribution, formal language markers, and paragraph structure uniformity that differ between AI and human writing.
The tool combines these analyses using a weighted scoring system to provide an overall AI probability score. Results are presented with confidence levels based on text length and analysis quality. All processing happens entirely in your browser using client-side JavaScript—no text data is transmitted to servers, ensuring complete privacy and security.
This AI content detector is particularly effective at identifying text generated by ChatGPT, GPT-4, Claude, Gemini, and other large language models. The detection accuracy improves with longer texts, as more data allows for better pattern recognition and statistical analysis.
Is AI Content Detector Reliable?
AI content detectors provide useful indicators but are not 100% accurate. The tool analyzes writing patterns and characteristics commonly found in AI-generated text, but results should be interpreted as probability estimates rather than definitive proof. Human writers can sometimes produce text that appears AI-like, and advanced AI models can generate text that closely mimics human writing.
For best results, analyze longer texts (200+ characters) and consider the context of the writing. The tool is most effective at identifying clearly AI-generated content with uniform patterns and predictable structures.
