StudyCorgi ChatGPT Detector is an online AI-writing detector for essays and other text, analyzing how likely a generative model would be to choose particular words in their surrounding context. A user pastes the material to be checked and may add a topic, title, or short description; the service then returns a proportional bar chart and word-level analysis instead of a conventional plagiarism report. It is primarily intended for students and teachers examining characteristics of academic writing, although it can process other text that fits the input box.
Results group words into red, orange, green, and violet predictability categories, and each word can be opened to inspect its estimated chatbot-use probability and likely alternatives. The main text field accepts up to 4,500 characters, while the optional topic or description field accepts up to 250 characters, so longer documents must be handled outside a single submission. The official page states that the detector is not perfect; its colors and proportions are therefore indicators for review, not standalone proof of authorship or a replacement for human academic judgment.
