AI detection involves using advanced machine learning algorithms and models to identify AI-generated content. The primary goal of an AI detector is to recognize specific characteristics in the text. A typical AI detector is based on a language model similar to models used in AI writing tools. Detectors analyze two things perplexity and business. The lower they are, the more likely that the content is AI-generated. Perplexity refers to how unpredictable content is and how likely it is to confuse an average reader. AI tools like ChatGPT create content with low perplexity. As a result, a text makes sense and reads smoothly, however, it’s quite predictable. On the other hand, human writing has a higher level of perplexity.
