Nowadays, a part of the population has started to feel distrust towards any online content. And for good reason, it is becoming increasingly difficult to distinguish AI-generated content from content written by humans. 

Image, video, deepfakes and text generators are disrupting the use of the internet. In the literary world, ChatGPT was a hit, gathering over a million users in just one week. However, once the excitement wore off, many people wondered how to differentiate texts created by ChatGPT from texts written by humans. 

Fortunately, there are several tools that can help prove that the text you are reading was generated by ChatGPT. 

In the next few minutes, we’ll take a detailed look at how AI detection works and introduce you to three methods for analyzing text and determining whether or not it was written by ChatGPT.

How does Artificial Intelligence work?

All artificial intelligence tools are data-intensive. Imagine having to read billions of articles to teach a system to detect patterns in text, such as syntax and word order. 

AI can be thought of as a computer brain that can think and learn, opening up a world of unlimited options. If you want to teach a robot to play a game like checkers, you will first need to show it how to move the pieces around the board before letting it play against other computer programs or real people. 

As the robot plays more games, it gradually learns how to play checkers by practicing. The robot is considered “smart” in games because of an algorithm, which is a set of instructions telling it how to approach the game and make decisions. 

For example, the program may tell the robot to look for specific patterns on the board. It improves by following these rules and making intelligent decisions with each new game. 

The term “Machine Learning” refers to one of the many types of algorithms used by AI. Machine Learning algorithms are amazing and allow the robot to progress on its own, without the need for regular instructions. And to help the robot learn faster, the algorithms use “training data,” which are large libraries of illustrations showing the robot what the best, most effective checkers moves look like.

So the robot’s understanding of how to play checkers improves in proportion to the amount of training data it has.

How does an AI content detector work?

Teachers, HR professionals, and students have all tried to determine if ChatGPT was the source of a text. But ChatGPT does not tag the content it creates at this time. 

So how can we verify the authenticity of generated content? 

That’s where AI detection tools come in, looking at the likelihood of each word’s appearance based on previous words. AI recognizes and replicates pre-existing patterns very effectively, but it only predicts words. For example, typing “Hi, I hope you’re okay. I wanted to know if_” on your phone, the tool predicts the next word based on the text to the left. 

The AI uses all of its training data to discover patterns in word usage in various situations. The more predictable the content, the more likely it is that it was written by a robot, because humans are spontaneous and inventive in their writing style, unlike bots that simply repeat learned patterns.

How to identify a text generated by ChatGPT?

There are many detection tools and programs that can identify whether a text is written by an artificial intelligence or by a human being. These tools work in different ways to determine whether a text is generated by an AI or not. Detection methods are grouped into two broad categories: 

Linguistic analysis and comparison with already known AI-generated text.

Linguistic analysis can reveal features such as a lack of semantic meaning or a tendency to repeat, which are often associated with AI-generated text. If a text resembles a previously known AI-generated text, this may be a sign that it was also generated by the AI. There are many different techniques within these two categories, some of which are a mixture of both.

In this article, we have identified the best AI-generated content detection tools in 2023, designed to spot content from ChatGPT and GPT3. Note that some of these tools also have other functions, such as content generation or plagiarism detection. 

These tools are advantageous in that they can identify falsified content and guarantee its human origin rather than its artificial origin. Most of these tools are available free of charge, making them accessible to everyone.
