One detector is a guess.
Four is a verdict.
Independent research has shown that any single AI detector — no matter the brand — produces false positives. That means real student work, real journalism, real prose gets falsely flagged as AI. The fix isn't a better detector. It's consensus.
false positive rate from a typical AI detector — meaning 1 in 20 real human writers will be falsely accused of using AI.
When you require three or more detectors to agree before flagging a piece as AI, the false positive rate collapses to effectively zero.
Arizona State University researchers proved that aggregating detectors eliminates false positives.
"Using 4 detectors in aggregate reduced the likelihood of detecting a false positive to nearly 0%, and this strategy was validated against human-rated labeled positives. Taken together, our findings show that AI detectors, when used together, become a powerful tool to inform instructors."
Top detectors correctly identify AI-generated text nearly 94% of the time across peer-reviewed tests.
Even the best individual detectors fail in about 1.5% of cases, flagging real human writing as AI.
Requiring two detectors to agree roughly halves the false positive rate to approximately 0.56%.
Four detectors in agreement brings the false positive rate to a theoretical minimum near zero.

Disagreement is the signal.
When all four detectors flag a piece as AI, you can trust it. When they disagree that's information too, we show you the per-detector split so you can make the call.
False positive rates derived from Hyatt et al. (2025). Our 4-detector implementation extends the validated 3-detector methodology with an additional independent signal.
