GPTZero: Online AI Involvement Detection Tool
Over the last few months, advancements in AI technology have put the higher education world on high alert. The release of chatGPT, for instance, has prompted students to turn to AI-generated content to cheat on assessments by writing essays and theses. While we can’t categorize AI-generated content as “plagiarized” in the traditional sense, since AI tools create entirely new and fresh material, honestly speaking, it is not ethical for students to present AI generator work as their own. Doing so undermines the purpose of learning and deprives them of valuable educational opportunities.
The text generated by the chatGPT chatbot seems so natural and humanly written that it’s becoming increasingly challenging for instructors to determine whether students’ work is original. To help teachers in this scenario, a computer science graduate, Edward Tian, developed an online AI involvement detection tool, GPTZero.This tool can determine whether a text has been generated artificially, making it easier for teachers to identify instances of AI-generated content. This article will delve into GPTZero, how to use it, and how it detects AI-generated text. So, let’s get started!
What is GPTZero?
GPTZero is a machine learning language model by OpenAI developed to distinguish between human-written and AI-generated content. Unlike its predecessors (Other GPT models), which relied heavily on extensive datasets, GPTZero stands apart with its significantly fewer parameters, making it more computationally efficient and quicker to train.

Remarkably, this model is not trained on any specific data set; instead, it leverages unsupervised learning algorithms to produce text from scratch. This is the #1 AI detector with more than 1 000 000 active users. By utilizing variables such as Burstiness, GPTZero can identify AI involvement with remarkable accuracy. It autonomously develops an understanding of language without external training data or pre-existing models.
Who and How created GPTZero?
22-year-old Princeton student Edward Tian, a computer science major, creates GPT-0. He spent part of his college winter break developing this AI detection tool while working with Princeton’s Natural Language Processing Lab. He claims in many of his tweets that this program can “quickly and efficiently” determine whether a human or chatGPT wrote a text. According to Tian, his motivation behind the development of the tool was simple- increasing AI plagiarism in academics, which has severe consequences and can harm students’ academic careers.

Tian’s developed online technology is available for instructors across the world free of cost to assist them in identifying plagiarized essays and assignments and assigning grades based on student effort.GPTZero was initially released on January 2, 2023, and became so popular that more than 20,000 educators have already signed up to receive updates on GPTZero’s development. On February 21, 2023, A tweet from Tian exposed that GPT-0 is Now parenting with an ed-tech organization like K16 Solutions to make the tool more powerful by training it on larger datasets.
The classic version of GPTZero is free to use as of March 2023, but that free version is limited to 5000 characters per document and can only batch analyze 3 documents at a time. But it also comes with 2 premium plans, GPTZero Pro and GPTZero Educator, for users who want to analyze millions of words monthly. In the premium version, the character limit is higher, and it allows the analysis of unlimited documents in batch analysis mode.
How Does GPTZero Works?
Are you wondering how ChatGPT determines whether the text is AI generated on human writing? Let’s dive deeper into this fantastic tool’s inner workings! According to Tian.GPT-0 measures 2 properties, perplexity, and burstiness, in a text to check whether humans crafted or artificially generated it. Before going into further details, let’s explain these 2 terms:
Burstiness
It measures the difference in the length of sentences in text. It means it considers the non-common items in random clusters’ The sentence structure and length in AI-generated text are more consistent than in human writing. The greater the burstiness of a text, the lesser its chance of being AI created.
Perplexity
It measures the randomness of text. Text written by human beings tends to be more random and confusing, while that written by AI is less random. Greater the perplexity value, the higher the chances that a natural person and vice versa write the text. Besides verifying text directly generated from AI writing tools, GPT-0 boasts the remarkable ability to identify and pinpoint parts of text taken from language learning models such as chatGPT. Educators can effortlessly upload multiple files and verify if their pupils are engaging in academic misconduct.
How to Use GPTZero?
GPTZero doesn’t require any pre-registration as in the case of ChatGPT. You can directly access the tool from the official website and use it per your needs. Let’s see how you can use it.



GPTZero Educator Account
GPT-0 has a product waitlist to give personalized solutions to educators by creating GPTZero Educator Account. The educators can seamlessly signup for this account by visiting the official website and filling in the required information.

According to the March 2023 mark GPT-0 website, their product waitlist is an exclusive feature only for educators. You may get confused while registering if you’re a regular user other than an educator. However, if you have some interest in technology, then on GPT-0 homepage, you can provide your email address under the Technology option to get the latest technological updates.
GPTZero Online Application Examples
GPT-0 can be used to detect the following:
How Does GPTZero Differ From Previous GPT Models?
Some of the significant differences between GPTZero and other language models of GPT are mentioned below:
Way of Training
One of the most significant differences between these models is the method these are trained on. GPTZero is virtually trained on no data, producing real-time results without depending on any pre-existing model or training data. In contrast, other GPT models are pre-trained on large data sets.
Way of Generating Text
ChatGPT generates text from scratch;this is supposed to be more creative and original in the text it generates. While previous models can’t create text from scratch, instead, they predict the next word in a sentence and then generate text based on it.
GPTZero Pricing
The March 2023 statistics show GPTZero is currently accessible as a classic beta version. However, it is anticipated that when the final version will be released in near future, it may require a subscription fee.
The Technical Principle of GPTZero
OpenAI, the owner of many other large language models, such as ChatGPT, releases GPTZero. According to GPTZero’s official website, it detects AI using the same technologies used to build ChatGPT. For this reason, we believe that its technology is based on GPT-3 model. However, GPT-0 detects AI involvement using Burstiness and perplexity variables.
Wrap Up
After all this discussion, we’ve reached the point that the GPTZero online AI involvement detection tool represents the new generation of language models that use a new approach to natural language processing. It generates text from scratch without relying on pre-trained data and thus is the most potent AI deception tool. For Now, only the beta version has been released, so it’s believed that with time, this model will evolve to revolutionize the language processing way and open up new opportunities for creativity. Only time will tell how far this tool will go, But it is evident that 2023 will be the most revolutionized year for artificial intelligence.
