AI detection tools like Turnitin AI, GPTZero, and Copyleaks claim to identify AI-written text — but how reliable are they?

The Uncomfortable Truth

• All current AI detectors have significant false positive rates — sometimes flagging human writing as AI
• Non-native English speakers are disproportionately flagged
• Lightly edited AI text often passes detection
• Different tools give wildly different results on the same text

What Experts Recommend

• Use detection as one signal among many, not as proof
• Never accuse a student based on AI detection alone
• Focus on assignment design over detection
• OpenAI discontinued its own AI detector due to unreliability
