Knowing what GPTZero looks for in a text is an important first step to making it undetectable.
How GPTZero Recognizes Text: The Perplexity & Burstiness Algorithm
GPTZero uses its unique classifier to evaluate text. It was developed based on extensive experience working with huge datasets consisting of AI- and human-written articles. It evaluates the following factors:
- Perplexity: Perplexity measures how random the choice of words is. Artificial intelligence predicts which word comes next, and if the algorithm recognizes it, then you use very logical word chains that will be easily recognized as AI text.
- Burstiness: When humans write, we tend to make our texts interesting. One long and descriptive sentence may be followed by another that is shorter. GPTZero finds the burstiness rate to detect this feature. If the text demonstrates low burstiness, then it was created by artificial intelligence.
Steps to Pass a GPTZero AI Detector Check
To bypass the GPTZero detector, you need to improve the entropy of words, i.e., introduce unpredictability in your vocabulary, as well as add more burstiness, which means varying your sentence lengths.
- Entropy: Don't use predictable word chains. Replace traditional transitions like "Furthermore," "Therefore," and "In conclusion," with natural and conversational ones.
- Sentence Lengths: Include short sentences as well as longer and more complex ones. This will introduce burstiness to your text.
- Paragraph Entropy: Make your paragraphs varied. For example, create some short and highlight-style paragraphs, as well as larger and detailed ones.
- Use a Dedicated AI Humanizer: Save yourself hours of work with manual rewriting. A quality humanizer tool can convert your entire document to human-level text in seconds.
