What Is GPTZero and How Does It Work? (Unveiling the Truth)

What is GPTZero - AnswerIQ

Most of us are aware that AI-powered chatbots and software have taken the world by storm in recent days, especially ChatGPT, which was launched by OpenAI and is considered to be transforming human-AI interaction.

If the use of such artificial intelligence tools is booming, then we really need a solution to prevent it. For example, ChatGPT is being used by many students, bloggers, and others to generate content for different reasons. However, using such AI-driven chatbots or tools to produce content is not always acceptable, so how can we tell if the generated content is from an AI chatbot or a human?

AI Content detector comes in handy in this situation. AI content detectors are specialized tools that examine the language and context of generated text using NLP and artificial intelligence algorithms. With the help of these tools, you can determine if a human or a machine created that particular piece of content.

In this article, we’ll look at one such tool named GPTZero. We’ll cover everything about this tool, like what GPTZero is, how it works, and how one can use this AI tool to detect ChatGPT-generated content.

So, let’s get started.

About GPTZero

GPTZero is an easy-to-use AI content detector that lets you detect whether the content is written by a human or generated by AI tools. Further, this tool generates an easy-to-understand report that shows the outcomes.


And the best part is that the tool is free, which means you don’t have to pay a single penny to use the power of GPTZero.

Who Develops GPTZero?

Nowadays, machine-generated or AI-generated content has recently increased due to models or technologies like GPT-2, GPT-3, and now ChatGPT. As a result, this artificial text is becoming more challenging to differentiate from human-written content. 

Hence, to overcome this problem, Edward Tian, who is a computer science student from Princeton University, developed GPTZero and launched it on 2 Jan 2023. The primary aim of this tool is to recognize artificially generated essays and other writing work.

How Does It Work?

The GPTZero software developer claims that it can quickly and effectively determine whether an essay is written by ChatGPT or by a human. 

GPTZero has two parameters: “burstiness.” and “perplexity,” which will help you differentiate ChatGPT-generated and human-written content. 

Perplexity is a metric that is used to measure text complexity. GPTZero uses the GPT2 model to assess perplexity. Lower perplexity indicates that the content is easy to recognize and hence seems more machine-generated. Conversely, human-written content is more unpredictable and has a higher level of perplexity.

On the other hand, burstiness measures how randomly the text was written. This way, GPTZero is able to accurately identify whether a ChatGPT or a human wrote a piece of content.

Note The more content you enter into the app, the more accurate results you will get. Also, please remember that GPTZero is still in the beta version, so you can’t entirely rely on this tool. 

Is GPTZero Accurate?

The accuracy of GPTZero is a matter of some debate. OpenAI, the organization behind GPTZero, claims that the tool has an accuracy rate of more than 98%. However, independent tests have shown that GPTZero’s accuracy can change based on what kind of text is being analyzed.

For example, GPTZero is better at finding AI-generated text that looks like a person, as ChatGPT wrote it. But it hasn’t been as good at finding AI-written text that is very different from human-written text, like GPT-4.

How To Detect ChatGPT Written Content Using Gptzero?

To identify ChatGPT-generated content using GPTZero, follow the below-mentioned steps:

Step 1: Type https://gptzero.me/ in your browser.

Step 2: Scroll down; here, you will find the “Try it” button; simply click on it.

Step 3: You will be redirected to the new window, where you will find the “input text box” you will need to input the text here that you want to check.

For example, we have written a short paragraph on “What is ChatGPT” and pasted it into the input box, then pressed Ctrl to enter button; it will take some time to analyze.

You can scroll down to read how this algorithm works, and then at the bottom of the page, you will find the result, whether the text is human-written or ChatGPT generated.

GPTZero Analyzing Overview

As you can see, this tool has provided its result, which shows the text we entered is likely human generated.

Now use the ChatGPT to generate some content on the same topic. 

So this time, we have pasted the ChatGPT-generated content into the input box.

Now, let’s see what the result is.

AI Generated Overview

So, this time it has detected that the content is AI-generated text.

As you can clearly see that this tool has analyzed the content and detected that the content is Ai generated or human-written.

That’s it! This is how you can check whether the essay or text is human-written or AI-generated.

But remember that the tool is still in beta version, so there is a possibility that you will not get the accurate result every time. So, you can’t be fully dependent on this tool.

Wrapping Up: GPTZero

GPTZero offers a number of advantages, including the ability to detect AI-generated plagiarism caused by the risen demand for ChatGPT. Furthermore, the website hosting of this tool has collapsed due to massive traffic, indicating a huge demand for GPTZero.

Overall, GPTZero is an excellent help for anyone who wants to avoid AI plagiarism caused by ChatGPT.

With that, we are wrapping up this article and hope that you will find this helpful and informative. You may ask in the comment section below if you have any questions. We would love to answer your queries.


What are the advantages of GPTZero?

GPTZero is rather simple to use. It is available via a simple API, requires no specific training or knowledge, and is completely free to use.

How can I ensure the accuracy of the content that I generate with GPTZero?

After GPTZero has generated content, its accuracy must be verified. Cross-referencing the text with additional sources makes this possible.
