Therabot was developed using the MERN stack—MongoDB, Express.js, React, and Node.js—providing a scalable and dynamic web application framework. GPT-3.5 was fine-tuned with a specialized dataset of therapeutic dialogues to ensure the AI delivers empathetic and contextually relevant responses. Prompt engineering was employed to craft effective interaction scenarios and maintain coherent conversations. This integration of technologies allowed Therabot to offer a sophisticated virtual therapy experience, combining robust backend infrastructure with an advanced, responsive AI capable of personalized mental health support.
