MindMate – AI-Powered Emotional Support Chatbot

Project Overview
  • Project Title: MindMate – AI-Powered Emotional Support Chatbot
  • Domain: Edtech
  • Technology Stack: Node.js , Express.js , React , MongoDB
  • Duration: 3 Weeks
Project Description

MindMate is an AI-powered chatbot designed to offer empathetic, non-judgmental emotional support to users struggling with stress, anxiety, depression, or loneliness. It simulates conversation using NLP to detect emotional tones, responds with comforting, psychology-informed messages, and suggests personalized exercises like journaling, mindfulness, or CBT techniques. It is not a replacement for licensed therapy but serves as a first line of support or a companion between therapy sessions.

Key Objective
  • Provide 24/7 emotional support via an AI chatbot.
  • Use sentiment analysis to detect user emotions and respond accordingly.
  • Help users practice mental wellness with guided activities.
  • Maintain confidentiality and anonymity to reduce the stigma of seeking help.
  • Escalate or refer users to professional help if serious distress is detected.
Core Feature
  • AI-Based Chatbot Interface with conversational memory.
  • Sentiment and Emotion Detection using NLP (detect sadness, anxiety, anger, etc.).
  • Mood Tracker: Users can log and visualize their daily emotional state.
  • Personalized Recommendations (e.g., guided breathing, journal prompts, CBT tasks).
  • Daily Check-ins: Gentle reminders to reflect or talk.
  • Anonymity Mode for user privacy.
  • Crisis Detection: Identifies potentially harmful language and alerts emergency support (with user consent).
  • Document Classification & Tagging (e.g., Confidential, Public).
  • Secure E-Signature Workflow (via DocuSign / HelloSign API).
  • Multilingual Support (optional): Handle support in different languages using translation APIs.
  • Chat History and Reflections: Users can revisit conversations and insights.
  • Progress Reports: Weekly emotional health reports with patterns and trends.
Ethical & Privacy Considerations
  • All data are anonymous and encrypted.
  • Informed consent before any data is stored.
  • Strict content filters to avoid misguidance.
  • Clearly communicated that it is not a licensed therapist.
