This study examines the effectiveness of an automated translation chatbot used in online interactions which consequently could enhance second/foreign language (L2) competence. Based on the sociocultural perspectives of learning, such as communication to recognize the difference from others and to be involved in sense-making processes, this study examines the automated translation chatbot to translate L1 statements into L2 automatically during online interactions by hypothesizing that the chatbot provides a variety of L2 comprehensive input and lowers learners' anxiety to write their L2 posts, which will lead to successful L2 learning. To verify our hypothesis, quantitative and qualitative data was collected by the online interaction, essay writing tasks, and open-ended questionnaire before and after the interaction. The findings of this study will suggest that the efficient use of an online translation bot facilitates collaborative dialog and results in more successful L2 learning.
