Why AI Essay Detection Matters#
As AI writing tools like ChatGPT become widespread in education, teachers and professors need reliable ways to identify AI-generated submissions. Students also benefit from checking their own work before submission to ensure it doesn't inadvertently trigger AI detection flags. Our AI essay checker is specifically calibrated for academic writing styles.
How to Use the AI Essay Checker#
Paste any essay, paragraph, or paper excerpt into the checker above. You'll receive an AI probability score, a 5-signal breakdown covering perplexity, burstiness, and structural patterns, plus a plain-English verdict explaining the result. For best results, submit at least a full paragraph (150+ characters).

For Students: Check Before You Submit#
If you've used AI tools to help draft or edit your writing, running it through our AI essay checker lets you see how it scores before submission. This helps you understand which sections may raise flags with tools like Turnitin and where to add more of your own voice and original thinking.
Calibrated for Academic Writing#
Our AI essay checker is specifically tuned to reduce false positives on non-native English speakers and students with naturally formal writing styles, while accurately flagging AI-generated content. Academic writing often has characteristics similar to AI output (formal tone, structured arguments), so our tool accounts for this. Learn more about how accuracy varies across different writing styles.

For a thorough review of academic work, combine our AI essay checker with the plagiarism checker to verify both originality and human authorship.
