By storing user details, the system enhances convenience and personalization for users. The findings demonstrate that automated chatbots can effectively streamline tasks across different domains, including booking sessions, making reservations, and resolving queries. Ultimately, this research highlights the potential of chatbot automation in improving efficiency and user experience in therapy session management and beyond.
