🛡️ PranaRakshak: A WhatsApp-Based Public Safety Chatbot 🚀 Inspiration The genesis of PranaRakshak stemmed from the critical need for timely and accessible public safety information. Recognizing that many individuals rely heavily on WhatsApp for communication, the idea was to leverage this platform to disseminate real-time emergency alerts and local resources efficiently. The aim was to bridge the information gap during emergencies by providing instant updates directly to users' fingertips.
📚 What I Learned Throughout the development of PranaRakshak, several key learnings emerged:
Natural Language Processing (NLP): Integrating Google's Gemini AI enhanced the chatbot's ability to understand and process user queries effectively.
WhatsApp Business API: Gained hands-on experience in setting up and managing interactions through the WhatsApp Business API, ensuring seamless communication with users.
Real-Time Data Handling: Learned to fetch and process live data to provide up-to-date emergency information.
User-Centric Design: Emphasized the importance of creating intuitive and accessible user experiences, especially during high-stress situations. Gist
