The emergence of Artificial Intelligence (AI) has significantly improved English as a Second Language (ESL) in higher education. AI tools like Wordtune, Questgen AI, Duolingo, Taskade, and Memrise can help learners improve their language skills, improve intercultural understanding, and enhance communication abilities. These tools play a crucial role in global corporations and AI-dependent industries. Wordtune is an AI-driven writing tool that enhances language skills by identifying grammatical errors, providing instant feedback, and suggesting alternative words, thereby improving accuracy and fluency. Questgen is an AI tool that creates interactive learning materials, assessments, and language practice tasks, including vocabulary quizzes and flashcards, to aid learners in memorizing and reinforcing new words. Duolingo is a language learning app that uses gamification to make language learning enjoyable for all skill levels, offering personalized feedback and points. Taskade is a tool that enhances language learning productivity by facilitating collaboration, planning activities, monitoring progress, and promoting motivation among learners. Memrise is a popular language learning app offering interactive courses, multimedia elements, spaced repetition, and community features like discussion forums and social sharing. Thus, this paper deals with the ebb and flow of afore-mentioned AI tools in learning English as a Second Language. The authors would analyse the use of AI tools in accelerating the progress of students’ English language learning as a second language in the age of AI.
