Artificial intelligence is changing the approach towards event planning, management, and organization. In conventional event management, scheduling of events, booking of venues, customer interaction, and other factors are done manually, making them cumbersome tasks. For overcoming the drawbacks of manual approaches, an AI-based event management system is designed.  With the help of this system, a user is able to plan and book various events such as wedding events, birthday parties, corporate events, cultural events, and others on a web portal. The user can choose event categories, themes, packages, and services according to his/her need. The AI system is used for scheduling, booking management, and customer interaction.  An AI-powered chatbot application is implemented in this system that will help users to get assistance about event packages, price list, booking process, and other queries related to customers. Administrators of the application can easily manage bookings, upcoming events, and completed events. The admin panel will also enable administrators to monitor revenue generation and customer reviews of events. The system is built using HTML, CSS, JavaScript, React.js, Python, and SQLite programming languages.
