In the final paper, I will write about the impact of the most widespread tool of artificial intelligence, which has certainly changed the general public's view of artificial intelligence, the impact of ChatGPT on the school system. It is a well-known fact that during registration, in order to be able to use this tool at all, it is necessary to confirm that the person is 18 or older, and otherwise, the confirmation of a parent or guardian who will supervise the use is required. In addition, it is recommended that children under the age of 13 do not use this tool. In my paper, I will look at the negative impact and/or long-term consequences that ChatGPT can have if these rules are not respected. This revolutionary tool, which is available to anyone with Internet access, has a handful of functions that contribute to education and make the work of teachers easier. It helps students with learning foreign languages and provides the necessary help with understanding syntax, it can also help with simpler tasks in chemistry or provide a required historical overview. All this can only be achieved if the student knows what he is looking for and how to enter the command correctly. Furthermore, I am talking about the difficulties it causes for teachers because students can assign the tasks assigned for homework to ChatGPT itself and copy the solution word for word. This may seem harmles but i could have very dangerous consequences, which I will explain in detail in the paper. ChatGPT can make the work of teachers much easier and provide them with an insight into new ways of organizing the lesson or the material itself, and can also become a topic of conversation in class. Artificial intelligence has been developing for over 50 years and entered the school system gradually. One of the things we can expect in the future is that teachers will teach students how to use them in an educational and safe way.
