+- **Extend APIs**: Presently, it has been integrated with weather API only. Extend it to railway APIs for showing live train status, train between two stations, schedule and other stuffs.

+- **Schedule reminder**: This is more like your chatbot assistant. Extend the program to schedule a reminder for specific date and time and should ping the user accordingly with meaningful messages.
