Technology has advanced rapidly and has brought with it the development of Artificial Intelligence (AI), which offers multiple possibilities in the process of learning English as a foreign language. This is how ChatGPT is currently being used by the majority of teenagers due to its ease of access, availability, speed, accuracy, flexibility, among others. In the educational context it is being used to provide instant and precise answers to questions and requirements posed by students and teachers. The purpose of this essay is to analyze the bibliographic review about the research project: Impact of ChatGPT on the Learning of English as a Foreign Language in Adolescents. The educational reality is permeated by the implementation of Artificial Intelligence and therefore, it is essential to consider its impact on the learning of English. ChatGPT has generated an undeniable impact on today's society. For that reason, it must be studied in order to establish whether it provides reliable and adequate strategies and mechanisms that strengthen and enhance the learning of English as a foreign language; especially in adolescents.
