AI Written Content Detector

With the spike of GPT AI, students are using it to generate essays and text based research assignements. Due to the nature of the way AI generates text, there is a way to differentiate text written by a human and text written by AI. 2 measures; perplexity & burstiness. Perplexity measures the complexity of a sentence while burstiness compares variation across sentences. Lower values increase the chances that the text was written using AI. "GPTZero is a classification model that predicts whether a document was written by a large language model, providing predictions on a sentence, paragraph, and document level. GPTZero was trained on a large, diverse corpus of human-written and AI-generated text, with a focus on English prose."  - https://gptzero.me/faq Using an API from GPTZero, I created a Google Marketplace extension to detect if text on a Google Doc was AI written.

Note the increase of the perplexity measure when analyzing the human written text. I used ChatGPT for the first sample and wrote the second sample.
