The AI detector industry should be very uncomfortable reading this MIT report.

The strongest institutional rejections yet, direct from MIT.

"we recommend against relying on AI detectors. "

"As it risks an arms race in which students respond to automated detection by using increasingly powerful “AI humanizers” to remove signals that AI detectors are cued to catch. The result: a lot of effort on both sides that in the end serves no one."

The report argues that mixed human/AI writing is difficult to detect, detectors can be evaded by “AI humanizers,” false positives can harm students, and heavy policing creates distrust.

AI detection systems may also mistake the writing of non-native English speakers or neurodivergent students for text generated by AI. Even low rates of false positives can put students on edge and cause serious individual consequences."
