Chat bots are lightweight messaging apps that can be used for customer service, booking, and simple interactions. They have over 2 billion active users across platforms like Facebook Messenger, WhatsApp, and WeChat. ReignDesign proposes building chat bots for conferences, education, banking, automotive, hotels, and insurance to provide information to users and complete basic tasks. They demonstrate this through a case study of a chat bot created for a mobile industry summit in Thailand that 37% of attendees used to get live agenda updates and venue information.
