Rajasthan Government coducted a National level Rajasthan Hackathon 4.0. The problem we targeted is the complaint registration between the government and the public. We used Dialogflow (Google's NLP sdk) to make a smart chatbot that can talk to both in Hindi and English. It takes your complaint and registers it in the database.
We also added smart energy consumption prediction which can predict based on the past data that how much electricity consumption will be consumed in the following months. Also there is a marketplace which can tell relatime fruits and veggie price in any city of Rajasthan.
