Yes, AI detectors can be wrong. These tools analyze text for patterns typical of AI-generated writing, such as low perplexity and uniform sentence structure, but they are not infallible. False positives occur when human-written text is incorrectly flagged as AI-generated, and false negatives happen when AI content goes undetected. Studies show that non-native English speakers and formulaic writing styles (like legal or technical documents) are more likely to trigger false positives. This is why most educators use AI detection as one signal among many, not as a final verdict. For a deeper look at how these tools work and their limitations, read our guide on How Do AI Detectors Work & Can They Be Trusted? . Quetext's AI Detector uses advanced analysis to minimize false positives and give you a reliable confidence score.
