Artificial Intelligence (AI) in English Language Teaching (ELT) has transformed personalised learning by providing adaptable and tailored experiences to individual learners’ requirements. By analysing student performance and preferences, AI-driven personalisation increases engagement, allows for real-time feedback, and optimises curriculum design. This study investigates the transformational role of AI in digital learning settings, focussing on major applications such as intelligent tutoring systems, chatbots, voice recognition tools, and adaptive learning platforms. While AI improves accessibility and efficiency in ELT, difficulties like data protection, teacher preparedness, and equal access to technology remain. This paper examines the benefits and limits of AI-driven personalisation, giving insights into its developing role in ELT. The study also explores future paths for AI integration, emphasising the need for ethical frameworks, teacher training, and hybrid learning models to fully realise its capabilities in educating languages.
