Serene Space – AI Mental Wellness & Behavioral Monitoring System is an intelligent digital platform designed to support users in improving their mental health and emotional well-being. The system allows users to log their daily moods, sleep cycles, attention span, habits, and behavioral indicators. Using AI-based prediction models, the platform evaluates patterns and predicts ADHD likelihood and depression severity. Users can also upload facial images, which are analyzed using deep learning models for emotion recognition to detect states such as happiness, stress, fatigue, or sadness. Based on these insights, the system provides personalized recommendations, productivity tips, and micro-nudges that encourage healthier routines and emotional balance. The platform includes consultation features where users can book appointments with doctors and receive professional guidance based on their mental health reports. Doctors can manage consultation slots and review user reports to provide appropriate support. Administrators manage system operations, maintain data privacy, approve doctors, and ensure the accuracy of AI predictions. By combining behavioral psychology, artificial intelligence, emotion analysis, and professional consultation, Serene Space acts as a digital mental wellness companion that promotes emotional awareness, early detection of mental health issues, and improved quality of life.
