Independent language learning is paramount for those wishing to develop proficiency in a second or foreign language. Language learners often have few opportunities to communicate and interact actively in their target language. In this two-phase study, a chatbot was developed to assist second-language learners at a tertiary education institution in Hong Kong with independent language learning. I employed a questionnaire (N = 128) followed by semi-structured interviews (N = 12) to gain holistic insight into learners' experiences with the chatbot. The results suggested that the participants enjoyed interacting with the chatbot both in and out of class and perceived that it improved their English skills. These findings have implications for language teachers and the future development of chatbots. Copyright © 2023 Inderscience Enterprises Ltd.
