Abstract. The integration of Artificial Intelligence (AI) into education represents one of the most transformative shifts of the 21st century. Language learning, as a cornerstone of communication and globalization, has been particularly influenced by these technological advances. This paper examines how AI enhances the effectiveness of language learning through personalized instruction, adaptive platforms, real-time feedback, and interactive applications. It draws on existing research, evaluates case studies, and explores pedagogical practices supported by AI. The discussion addresses both the opportunities and challenges of AI in language pedagogy and suggests strategies for sustainable implementation. The findings highlight that AI can serve as a powerful complement to traditional teaching while presenting ethical, social, and technological challenges that must be addressed in future policies.
