OpenAI's Revolutionary Language Model.

How to detect ChatGPT generated content?

ChatGPT, a super-trained language model developed by OpenAI company, has a huge impact on our lives. It can create lots of different content on almost all domains at the user’s request. This, however, led to another challenge, we sometimes struggle or fail to detect ChatGPT-generated content.

Therefore, it has never been more important to detect if a text was written by ChatGPT as its trend is rising exponentially.

In certain fields, this is a particularly crucial issue as we may want to favor uniqueness or effort that is put into something. At some point in the future, we may completely fail to understand if a text is written by ChatGPT and AI may become an indistinguishable part of our lives. But before getting to that point, we will be discussing today the ways to identify real content versus AI-written content.

Can ChatGPT be detected?

How to detect ChatGPT generated content

While ChatGPT’s text generation is highly sophisticated, it is not foolproof. Take a look at mistakes that ChatGPT makes when generating responses. Trained AI detection tools can analyze various textual features and patterns to make an educated guess on whether a text is likely generated by ChatGPT. However, it’s important to note that the detection may not always be 100% accurate.

How to detect ChatGPT-generated content?

Now, let’s delve into the key aspects that can help us identify if a text is written using ChatGPT.

1. Unusual Phrasing and Vocabulary

When analyzing a text, pay attention to the phrasing and vocabulary used. ChatGPT may exhibit certain patterns and word choices that are less common for human writers. Look out for unusual word combinations or phrases that seem out of place. While it is trained to mimic human speech, it can occasionally produce idiosyncratic language.

2. Inconsistent Tone or Style

Human writers tend to maintain a consistent tone and style throughout their work, whereas ChatGPT might struggle to achieve the same level of consistency. Shifts in tone, abrupt changes in writing style, or inconsistencies in grammar can be indications of AI-generated content.

3. Repetitive Structures

ChatGPT’s training data consists of a vast corpus of text, which can sometimes lead to the repetition of certain sentence structures or phrases. If you notice recurring patterns or repetitive language that seems artificial, it may be a sign that the text was generated using ChatGPT.

4. Excessive Use of Transitional Phrases

Transitional phrases such as “in addition,” “however,” or “on the other hand” are often used to connect ideas and improve the flow of a text. While ChatGPT has been trained to utilize these phrases, it may overuse them or insert them inappropriately. Excessive or unnatural usage of transitional phrases could be indicative of AI-generated content.

5. Lack of Personal Touch

Human writers often infuse their work with personal anecdotes, experiences, or emotions. ChatGPT, on the other hand, lacks personal experiences and emotions, which can result in content that feels detached or lacking in the human touch. If a text lacks personalization or emotional depth, it might be generated by ChatGPT.

6. Overreliance on Information Retrieval

ChatGPT’s training data is sourced from a wide range of internet articles and publications, leading to a vast pool of information at its disposal. Consequently, it may rely heavily on factual information rather than providing original insights or perspectives. If a text appears to be a compilation of information without offering unique perspectives, it could be a result of ChatGPT’s training.

Is there a ChatGPT detector?

Yes, there are several detection tools developed for this purpose, but none of them have achieved 100% accuracy so far. These tools utilize various techniques and algorithms to analyze the characteristics and patterns of AI-generated content. They help identify if a text is likely generated by ChatGPT or similar AI models. However, it’s important to note that while these detection tools can provide valuable insights, there is still a margin of error in their assessments.

ChatGPT detector

We understood technically how we can detect ChatGPT-generated content. We will now provide a detector to use in order to understand if a text is written by ChatGPT. Please note that it may provide false-positive or false-negative results. To explain them briefly, take a look at the following descriptions.

A false positive occurs when a test indicates a condition when they do not actually have it. In this context, a false positive would be when a test indicates that a text was written by AI when it was actually written by a human.

A false negative occurs when a test does not indicate a condition when they do actually have it. In this context, a false negative would be when a test indicates that a text was written by a human when it was actually written by an AI.

There are many more tools available for detecting AI-generated content. For the purpose of this article, we will focus on one of them and it probably get your work done. Universities, however, may use more advanced tools for detecting AI-generated content for academic purposes, as this is a highly important issue in academia.

GPT Zero Detector

This is a tool that allows you to input a piece of text to determine whether it was generated by AI. You can access that by searching for “ChatGPT detector” in a search engine. Simply paste the text you want to test in the designated field, and the model will begin the detection process. The result will be displayed in the bar below upon completion.

So to test this app, I first asked ChatGPT to write me an essay about quantum physic. It gave me the following output. After reading it, I would have no idea if ChatGPT or a real human generated it.

I took the provided text and put it into the detector app by copying and pasting it. Here is the result.

the app understands that the provided content is ai-generated or fake

According to the detector, this text is 99.98% likely to be fake or created by AI. And this is astonishing as I have previously mentioned that I couldn’t able to detect it on my own.

It’s important to remember, however, that there is always the possibility of false negatives and false positives with any tool. As such, it’s important not to completely trust the results of this app, as we don’t know its rates of false negatives and false positives.

How do I know if my student is using ChatGPT?

As a teacher, you may wonder how you can detect a student who used ChatGPT for their homework.

Detecting if a student is using ChatGPT can be challenging but not impossible. Keep an eye out for sudden improvements in writing quality, drastic changes in writing style, or the use of uncommon vocabulary. Additionally, comparing their previous work with their current assignments can help identify any stark differences that might indicate the use of AI-generated assistance.


ChatGPT is a great tool and has the potential of helping us in every domain of our lives. One of them is content creation. And with the advent of ChatGPT, understanding the difference between AI-generated content and human-generated is both difficult and crucial. There are some detectors providing this service. While these tools are also evolving as ChatGPT does, It is important to be aware of false-positive and false-negative keywords.
