This study explores the attitudes and perceptions of preservice teachers regarding applications of Generative Artificial Intelligence, with particular reference to ChatGPT and their use in school. Functional elements emerge for professors, teachers’ trainers, instructional designers. There is interest and appreciation of the potential, caution in considering use in the classroom, and incomplete awareness of the specific characteristics. The ability to adapt texts is not perceived. Instead, confidence emerges in the reliability of the results when searching for information with the disbelief that they can be alternative tools to traditional search engines. The participants agree on the need for systematic and widespread training, which should involve preservice teachers, in-service teachers, and students.
