ChatGPT Detector
ChatGPT Detector is a free StudyCorgi web tool for checking whether academic text appears to be AI-generated. It helps students and teachers review essays or research papers using a bar chart and word-level analysis.
ChatGPT Detector
ChatGPT Detector is a free online writing-analysis tool on StudyCorgi’s Free Writing Tools site. It is designed to help students and teachers check whether an essay, research paper, or similar academic text appears to have been generated by AI.
The detector works by analyzing pasted text and presenting the result as a bar chart plus a detailed, color-coded breakdown of the words in the text. Users can add an optional topic or short description, then run the check to inspect which parts of the text look more predictable or less predictable for an AI generator.
The page frames the tool as a way to review academic writing that may have been produced with ChatGPT or a similar model. It does not describe an API, integration workflow, or export feature, so the core use is manual text checking inside the web tool.
What it does
Optional context field
Lets you add an optional topic, title, or short description to provide context for the check.
Probability-based chart output
Returns a bar chart that breaks the text into word groups based on how likely an AI generator would use them.
Word-level highlighting
Shows a detailed analysis with words color-coded by category so you can review the text line by line.
Word inspection and alternatives
Lets users click individual words to see their probability of being used by a chatbot and the top five likely alternatives.
Free academic-use access

When to use it
Essay review
Check an essay draft before submission to see whether sections read as highly predictable or AI-like.
Academic paper screening
Review a research paper or assignment that may include AI-generated passages and identify which words or lines deserve revision.
Revision support
Use the word-level breakdown to edit passages that appear too predictable and make the writing read more naturally.
Classroom discussion and review
Compare a suspicious text against the charted result to understand where the writing may be machine-like rather than human-like.
