What is Studycorgi ChatGPT Detector?
StudyCorgi's ChatGPT Detector is one of the free writing tools on the site, specifically designed for essays and academic texts. After pasting the content, it provides a word-level probability analysis: each word is colored according to "the likelihood that an AI would use that word in this context", accompanied by a bar chart showing the overall distribution. The official website states that it is free for both students and teachers. It is one of the free writing tool collections on StudyCorgi, positioned more for students to self-check rather than for institutions to make determinations.
Who is it for?
- College students who want to identify the specific phrases and sentences in their writing that are most likely generated by AI for targeted revision.
- Teachers who grade assignments one by one and need specific evidence rather than just a score.
- Researchers who draft initial versions of their papers with AI and want to reduce repetition.
- Learners who practice English writing and want to adjust their word usage habits.
- Non-native writers working on English papers who need to adjust sentences word by word based on word-level prompts.

How to use Studycorgi ChatGPT Detector
- 1The single-use limit is 4,500 characters. For long papers, conduct section-by-section checks and ensure consistent style across all sections.
- 2Filling in a topic or description can make the judgment more context-appropriate; leaving it blank will reduce accuracy.
- 3Colors are just probability hints; a high proportion of red and orange words does not mean the text was definitely generated by AI, and you need to make a judgment based on your writing process.
- 4If your goal is to reduce AI traces, prioritize revising the words and sentence structures marked in red instead of rewriting the entire text.
- 5Each university has different regulations regarding the use of AI, and the test results do not equate to compliance conclusions.

- 7The website also offers essay writing and rewriting services; please distinguish between free tools and paid services.
