ZeroGPT and false positives

A free detector with very high traffic, frequently the tool behind a casual accusation from a reader or client.

What it claims

Publishes no meaningful validation. It is a free tool with no stated error rate.

Where it fails

Because it is free and instant, it is the most likely source of an accusation made by someone with no expertise and no process.

How to respond

Establish what decision, if any, rests on it. Very often the answer is "none, I just thought you should know", and the conversation ends there.

Worth knowing

An accusation from a free detector is a social event, not an evidentiary one. Respond to the person, not the score.
