What is an AI Text Detector?
An AI text detector (also known as AI content detector or ChatGPT detector) is a sophisticated tool that analyzes written content to determine whether it was created by artificial intelligence or a human writer. Our free AI detector uses advanced natural language processing techniques including perplexity analysis and burstiness detection to identify patterns characteristic of AI-generated text from models like ChatGPT, GPT-4, Claude, Gemini, and other large language models.
How Does Our Free AI Detector Work?
Our AI detection tool employs multiple sophisticated algorithms inspired by leading tools like QuillBot AI Detector and GPTZero:
- Perplexity Analysis: Measures text predictability - AI text tends to be more predictable and uniform
- Burstiness Detection: Analyzes sentence length variation - humans write with more varied sentence structures
- Vocabulary Patterns: Identifies characteristic word choices and phrases common in AI-generated content
- Sentence Structure Analysis: Examines grammatical patterns and writing flow typical of AI models
AI Humanizer - Make AI Text Undetectable
Our integrated AI humanizer transforms AI-generated content to sound more natural and human-like. If your text is detected as AI-written, simply click the "Humanize Text" button to rewrite it with more natural variations, conversational tone, and human-like imperfections that help bypass AI detection tools.
