More and more people are discovering and are amazed at the capabilities of Chat GPT, the popular Artificial Intelligence program that is trained to understand human language and generate text. For this reason, it has already become a resource used regularly in various areas: students, content creators, professional writers... And that has given rise to the need to know to what extent a text has been written naturally or artificial. How to know if a text has been generated by ChatGPT?

It is an issue that worries teachers, who see how students use this "trap" when preparing their academic work. And also to website owners, who can see how Google penalizes their positioning by detecting duplicate content or content not generated by a human, but by a machine.

As a result of the evolution of this technology (and in response to these new needs), tools that allow us to detect texts generated through artificial intelligence. We are going to discuss them in this article.

What is ChatGPT?

Although there are already many users around the world who have tried ChatGPT or even use this tool frequently, it doesn't hurt to remember what exactly it is about. We talk about an artificial intelligence that has been trained to maintain conversations. The way to interact with it is very simple: all we have to do is ask questions in a conventional way. The AI ​​will understand them and provide us with an answer.


ChatGPT is based on the GPT-3.5 Artificial Intelligence language model, which has been developed by the company OpenAI. There are several versions. The last one to leave is GPT-5, which dramatically improves its capabilities with respect to GPT-4 and shows us that in the field of AI we are still going to witness many impressive prodigies.

Currently, this chat equipped with artificial intelligence is capable of providing accurate, truly complete and structured answers in several paragraphs, to user questions. He surprises with his natural way of expressing himself, which makes him truly difficult to distinguish their responses from those that a human could give.

However, perfection is still far away. Despite continuous improvements, ChatGPT still makes mistakes. And that is something that those who use this tool for professional or academic purposes must take into account.
