This study explores the development and evaluation of an AI-powered chatbot designed to provide empathetic mental health support [1]. The chatbot leverages Natural Language Processing (NLP) to engage users in reflective conversations while ensuring privacy and accessibility [2]. Through two survey-based experiments, the chatbot was tested for emotional engagement and user trust, revealing high comfort levels but also highlighting the need for improved emotion detection and transparency in data handling. Future improvements will focus on fine-tuning AI responses, increasing privacy assurance, and enhancing long-term user engagement. The chatbot serves as an accessible mental health tool, offering a judgment-free space for self-expression.
