ZeroGPT is the most commonly used AI detector that does not need you to sign up. Below, you will see how it works in practice.
How ZeroGPT Detects AI Text
ZeroGPT employs a model that relies on the same classification parameters as Turnitin, GPTZero, and Originality.ai, namely the perplexity and burstiness features. If the text exhibits low word choice entropy and uniform sentence length, it is classified as being written by an AI.
Where ZeroGPT Gets It Wrong
Our experiments showed that ZeroGPT identifies a significant amount of human writing, specifically:
- Technical and scientific writing, where terminology tends to be repetitive.
- Formal business writing, which often adheres to certain templates.
- Non-native English writing, which may appear more uniform in structure.
It is a known flaw in almost all AI detectors available for free, and not exclusive to ZeroGPT.
How to Bypass ZeroGPT
- Paste your AI-generated writing in an AI humanizer set to academic or formal tone.
- Allow the tool to rearrange the structure and vocabulary distribution.
- Rescan the new writing in ZeroGPT to make sure that the score has lowered into the human range.
In our tests, text generated with Humanize AI Pro had less than 5% chance of being an AI-generated text on ZeroGPT, while the non-edited draft showed
