This pilot study investigates the use of ChatGPT by university students in the context of foreign language learning. Drawing on a mixed-methods approach, the research examines how English and Romance Philology students incorporate the AI tool into their academic routines, both within and beyond the classroom. Quantitative data collected via questionnaire reveal that students most frequently use ChatGPT in out-of-class contexts, particularly for writing, vocabulary development, and grammar correction. Statistical analysis shows a significant preference for autonomous use over classroom-based application. Qualitative responses further indicate that while students appreciate the tool’s versatility and efficiency, they remain critically aware of its limitations, including occasional factual inaccuracies, mechanical style, and ethical concerns. The findings are interpreted through the lenses of Self-Directed Learning Theory, the Technology Acceptance Model, and Constructivist Learning Theory, suggesting that ChatGPT functions primarily as a complementary learning-support tool. The study concludes with pedagogical recommendations and proposes directions for future research, highlighting the need for AI literacy and teacher guidance in contemporary language education.
