Artificial intelligence is transforming the way companies manage technical service and after-sales support. This session presents a concrete case study of an AI-powered chatbot designed to assist corporate service teams and end customers in quickly resolving machinery malfunctions and technical issues. The solution enables users to interact in natural language and receive answers drawn from structured company sources: technical manuals, archived tickets, internal documentation, and other relevant data. The outcome is an intelligent system that expands corporate know-how and boosts operational efficiency.
