What Is an AI Detector and How Does It Work?
An AI detector (also called an AI checker) is a tool that analyzes a piece of text and estimates whether it was written by a human or generated by an AI model such as ChatGPT, Claude, or Gemini. As AI writing tools become more widely used in education, business, and content creation, the ability to detect AI-generated text has become increasingly important.
AI detectors work by examining statistical and linguistic signals in the text. AI-generated content tends to be more predictable in its word choices and sentence structure, a property known as low perplexity. It also shows less variability in sentence length and complexity, known as low burstiness. Human writing, by contrast, is naturally more varied and unpredictable.
Our AI content detector runs a deep-learning analysis on your text and returns an overall AI probability score, as well as a sentence-level breakdown showing which parts of the text appear AI-generated and which appear human-written. This makes it useful for quickly identifying AI-generated content within longer documents.
If our AI checker flags your content as AI-generated and you need to make it pass as human-written, you can use our free AI humanizer to rewrite it into natural, human-like text that bypasses AI detection tools.
