In recent years, numerous studies have shown that the spread of generative Artifical Intelligence (GenAI) is forcing a reform of pedagogical practice in higher education. GenAI can provide administrative support and create new opportunities for developing creativity, critical thinking, and autonomous learning [1]. One of the greatest challenges is the lack of AI literacy among students and instructors [2]. Research conducted in Hungary indicates that local educators mainly use artificial intelligence for routine tasks—such as text translation, information retrieval, and grammar checking—while deeper pedagogical opportunities, such as creating personalized learning materials, remain in the background [3]. In addition to technical and educational challenges, the use of GenAI also raises significant ethical issues. Many instructors are likely already actively using or allowing the use of ChatGPT, while formal guidelines are incomplete or outdated [4]. For instructors, students, and AI to be able to work together effectively, familiarity with AI tools and their conscious use are required, along with up-to-date institutional-level regulation of their use and, last but not least, a willingness to experiment. We sought to explore the attitudes and habits related to AI use among Hungarian and international students and instructors at the Faculty of Engineering of the University of Debrecen, with the aim of integrating AI into education as effectively as possible in the future. For this purpose, separate online anonymous questionnaires were administered to students and instructors. Respondents evaluated the statements using a five-point Likert scale. We received an overview of which AI tools our institution’s students and instructors mainly use, and for what purposes, in the course of their work. Among other things, we also get answers to the following questions. Is there any difference between the AI usage habits of our Hungarian and international students? Is there a difference between younger and older instructors in terms of how they use AI in teaching? Do students or instructors have greater distrust regarding the use of AI?
