Can AI Be Detected?

AI detectors mislabel real student work more often than schools advertise, especially for non-native English writers. Here's a practical response plan.

Colleges increasingly treat AI writing as an academic-integrity issue, and Turnitin-style checkers are common, but not universal, and policies differ wildly.

Turnitin built paraphrase detection partly in response to QuillBot, so paraphrasing alone is a weak shield. Here's the honest, current picture.

Claude writes more naturally than some models, but Turnitin's detector is model-agnostic, so Claude output can still be flagged. Here's the honest picture.

Turnitin can flag ChatGPT-written text, but its AI indicator is probabilistic, not proof, it produces both misses and false positives. Here's the honest, current picture.

Turnitin can flag AI-written text from any major model, but its indicator estimates likelihood rather than proving authorship, with real misses and false positives. Here's the honest picture.

Professors catch ChatGPT through both detectors and old-fashioned judgment. The human tells are often more decisive than the software. Here's the honest picture.

GPTZero is one of the detectors most tuned to ChatGPT output, but it's probabilistic and produces false positives. Here's the honest, current picture.

Canvas is an LMS, not an AI detector, but the Turnitin and similarity tools it integrates can flag AI, and its logs reveal more than students expect. Here's the honest picture.

AI detectors produce both misses and false positives. Honest human writing gets flagged every day, here's why, who's most at risk, and what to do about it.
