GPTZero is an online tool/webpage that uses a metric called “perplexity” to determine whether a given text was written by a human or an AI.
Perplexity is a commonly used metric in the field of natural language processing to evaluate the quality of language models.
When you input text into GPTZero, it calculates the total perplexity and average perplexity of all the sentences in the text. A higher perplexity value indicates that the text is more likely to be written by a human.
