GPTZero: All You Need To Know

Since the introduction of chatGPT, teachers have had a hard time distinguishing which test submissions were genuine or just a rip-off from chatGPT. But that is soon to end as a student from Princeton University created an AI detector tool capable of detecting any type of AI written text called GPTZero. In this post, I’m going to show you how the tool works, who created it, if it’s paid, and more.

What is GPTzero

GPTZero is an AI detector tool created by a student from the university of Princeton. It was created to help people find a solution to AI plagiarism whereby students or content creators instead of doing the hard work of researching and writing content or testing on their own, instead they turn to AI content generators such as chat gpt or chat sonic to do the work for them.

It’s a game-changer tool that will help educators deal with test submissions forged from content generators.


Name: Edward Tian

University: Princeton, USA 

Major: Computer Science

Minor: Journalism

Age: 22 years

In case you’re wondering who created GPTZero, well the founder of the ai detector tool is a student from Princeton University. A 22-year-old journalism minor student who majors in Computer science, going by the name Edward Tian. He spent his winter holiday working on the project, after hearing the chatGPT hype going around that students were using the revolutionary language models to do their assignments. He took the time to create the tool to help teachers deal with the issue.

And when introducing the project to his Twitter followers, he emphasized that we as humans deserved to know if a text was written by a human or ai. And that was what motivated him to create the project.

How Does GPTZero Works

In simple terms, GPTZero checks the complexity and randomness in the creativity of text samples to determine if a text was written by AI or a human being.

On the more complex side of how it does its work, take a look.

GPTZero is AI written text detector tool that uses two factors to determine if a text was written using chatGPT or any other ai writing tools. The factors include “burstiness” and “perplexity”. Whereby “burstiness” is the randomness of sentences, variation in length that is a short and long mixture, or variation in the text’s creativity. If the structure of the text is uniform then it’s most likely written by an AI and vice-versa.

On the other hand, “perplexity” measures the complexity of the text. That is if the text sample hasn’t been seen by the AI then the ai is most likely to be perplexed by the text.

In simple terms the higher the complexity of the text sample the higher likelihood it was written by humans. While if the complexity is low and the AI is familiar with the text then it’s most probably written using AI

How To Use GPTZero

Using GPTZero is very simple all you have to do is copy your text sample and paste it on the text area on the website then click check.

They also offer APIs that you can use to check ai plagiarism on your text programmatically.

They also accept most document formats for checking, so if you have a PDF file, DOX, or ODT file it will still check them and give the result you need.

Is GPTZero fee

GPTZero is completely free for use to everyone using the copy-paste interface when checking their texts.

YouTube 🔗

Edward Tain the creator said in an interview with Yahoo Finance that the simple paste interface will be free forever.

However, the people who would like to use the API to check their documents in bulk will have to pay for the request and usage.

Who Can Use This Tool

The ai plagiarism detector is available for all to use, whether you’re a teacher, student, or content creator. You can use it to double-check if the text submitted by the freelancer is unique and not AI written. All are allowed to use the tool for free.

How To Bypass GPTZero

Just like any other tool, you’ll find in need of ways to bypass the detection system. And it is really simple just like any other AI detector tool about there, all you have to do is rewrite the text generated from chatGPT or you can use the free and readily available article rephrase tools. Those will do the trick as described in this video on YouTube.

GPTZero Compared with Other AI Detectors

Originality Ai 

This is one of the go-to AI detector tools you can use and get the best results. What makes this tool shine is that it doesn’t only check for AI content, it also checks for any kind of plagiarism in the text.

After checking your text it gives out the results I’m percentage of how much the text is generated or not. It gives the percentage of plagiarism in your text if any and shows you the link to the source of the copied part.

I have used it before and I love how works it the only con compared to GPTZero is that it’s a paid tool, even the price of using is in cents but that’s where it differs from the GPTZero.

Content at scale

This is daily new but it does its work pretty well, it also uses the percentage to represent how much your text was ai generated in line with the GPTZero which uses the other method we discussed above.

Hugging Face

This is one of the fastest AI detector tools provided by a company called Hugging Face. The tool is open source and it’s completely free to use. The only difference between this and the GPTZero is just that it was made to detect texts generated by GPT-2, unlike GPTZero that’s capable of detecting any AI content in general. You can still use the Hugging Face AI detector tool and it will give a good result still.

Is GPTZero a Game Changer: Verdict

GPTZero came in a time of need when educators were overwhelmed with forged AI content submitted by students. It’s going to revolutionize how we see AI-produced content since we deserve to know and distinguish which articles or contents are AI-generated or written by humans.

According to me, I would say that it’s a game changer but still requires some work to improve it. The creator should focus on making it simple to use, and more so improve it so that it can also detect rephrased text to deal with AI plagiarism once and for all.

I hope this was helpful, remember to leave a comment below I would like to hear from you, anyways ✌️

I love coding and writing
