With the rise of artificial intelligence (AI) technology, it is becoming increasingly difficult to distinguish between human and machine-generated content. GPTZero, sometimes called ChatZero, is a powerful tool that seeks to address this problem.
It uses advanced algorithms to detect AI-generated content in conversations, allowing users to identify and take action on any suspicious activity. This article will explain how GPTZero works and how it can be used to help protect online discussions from malicious bots and other automated accounts.
GPTZero is a language model designed to classify text as either human-written or generated by an AI model. It was trained on a diverse corpus of human-written and AI-generated text, focusing on English prose. The following are three features of GPTZero:
1. Multi-Level Classification
GPTZero allows users to determine how much of a document has been generated by AI technology. It does this through multi-level classification, which analyzes the text on sentence, paragraph, and document levels.
On a sentence level, GPTZero can detect when AI or human writers have created portions of text. This allows for an accurate assessment of the amount of AI-generated content present in a given document.
For documents that return mixed results, GPTZero provides a score indicating the probability that the entire document was written using AI technology.
2. Perplexity Score
The Perplexity Score indicates how well a language model can predict a sequence of words. GPTZero computes this measurement for each document to determine the level of uncertainty the model has when trying to differentiate between human-written and AI-generated documents.
Measured on a scale, a low perplexity score tells us that the language model is confident in its prediction, while a higher perplexity score suggests that the model is uncertain. This metric provides valuable insight into how accurately the models can classify text as either human- or machine-generated.
3. Burstiness Score
The Burstiness Score is a metric used to measure the repetition of similar phrases or topics within any given document. GPTZero provides this score for every text piece to indicate the similarity level between different sections.
The higher the score, the greater the chances that an AI model was employed to generate such text since artificially-generated content often includes multiple repetitions of phrases and ideas. Businesses, researchers, and organizations who want to identify whether machines or humans wrote certain texts can use this type of analysis.
- GPTZero accurately detects whether a text is AI-generated or written by a human.
- Can be used to identify potential risks of using AI in written work.
- Works across various AI language models.
- Accuracy on shorter documents is lower

How to Use GPTZero
Step 1: Visit the GPTZero website
Step 2: Enter the text you want to analyze in the text box provided
Step 3: Click the “Get Results” button
Step 4: GPTZero will analyze the text using its “perplexity” and “burstiness” indicators to determine whether a human or AI wrote it
Step 5: GPTZero will highlight AI-Generated text as yellow
Comparing GPTZero to Other AI Platforms
To assess the accuracy of GPTZero’s content recognition system, we conducted a trial. We took sample content from Jasper.AI and ran it through GPTZero to see if it could identify that an AI (not a human) created the material.
|1||What is Jasper.AI?||80.05%||100%|
|2||How Does Jasper.AI Work?||41.48%||100%|
|3||Who Created Jasper.AI||44.70%||99%|
|4||Who is Jasper.AI for?||60.66%||92%|
|5||How much does Jasper.AI cost?||62.95%||62%|
|6||How to write an article with Jasper.AI?||69.46%||2.00%|
|7||Is Jasper.AI Free?||67.96%||99%|
The table shows the results of GPTZero’s AI-content detection tool and Originality.ai’s tool to check the originality and uniqueness of various titles related to Jasper. The scores obtained from Originality.ai were consistently higher than those obtained from GPTZero, except for the sixth title, where GPTZero scored higher.
Although GPTZero shows perplexity and burstiness scores, it could not completely detect that a human did not write the content. Hence, GPTZero’s AI content identification tool is not as reliable for detecting the originality and uniqueness of content.
It also doesn’t provide a plagiarism-checking feature. This can be extremely concerning for companies that strongly rely on content produced by AI, as it could result in potential copyright infringement.
Advantages of GPTZero
Despite the underwhelming results earlier, GPT Zero has several advantages. The significant advantages it can provide are perplexity scores, which measure how well the model predicts the next word in a sequence, and burstiness scores measuring the likelihood of a group of words appearing in a document consecutively.
Furthermore, GPTZero can detect a range of AI language models, including ChatGPT, GPT-3, GPT-2, LLaMA, and AI services based on those models.
All in all, GPTZero is an AI-powered tool designed to distinguish between human and machine-generated content.
It offers multi-level classification to determine the amount of AI-generated content in a given document, perplexity scores to measure the model’s uncertainty in differentiating between human and AI-generated content, and burstiness scores to indicate the degree of similarity between different sections of text.
While the accuracy on shorter documents is lower, GPTZero accurately detects whether a text is AI-generated or written by a human and works across various AI language models. The tool can identify potential risks of using AI in written work and help businesses, researchers, and organizations identify whether machines or humans wrote certain texts.
However, it is unreliable for detecting content originality and uniqueness and does not provide a plagiarism-checking feature.
AI writing tools are well on their way to becoming mainstream. ChatGPT only launched in November 2022, while GPT-4 was released in March 2023. As such, there is a great deal of interest in these AI tools’ ability to create fully-fledged writing pieces. But such innovation doesn’t come without ethical concerns. In the education space, […]
The future of artificial intelligence is here, and its name is GPT-4. Developed by OpenAI, GPT-4 is the newest and most advanced model in deep learning, capable of processing text and image inputs to produce human-like outputs. While still not entirely on par with human abilities, GPT-4 has already achieved impressive feats in various benchmarks. […]
ZeroGPT is a tool designed to detect whether a given text is generated by an AI tool like ChatGPT or Google Bard, or if a human writes it. Users can enter their text and analyze it with the tool’s complex algorithms, which use DeepAnalyse™ technology to determine its origin. The tool claims an accuracy rate […]
