Virtual Assistants and AI: From Design to Implementation of No-Code Chatbots in the Case Study of the Vicenza Digital Innovation Hub

This thesis aimed to design, implement and validate a no-code chatbot powered by the advanced capabilities of large linguistic models (LLM), with specific application at the Digital Innovation Hub (DIH) of Confartigianato Imprese Vicenza. The investigation explored the role of AI-based chatbots in streamlining operational flows, increasing organizational efficiency and facilitating interaction with users. During the study, several no-code platforms, including Landbot, Botsonic and Botpress, were examined to assess their strengths and limitations in terms of user experience, scalability and adaptability to the specific needs of the DIH. The process led to the creation of “DIBot”, a virtual assistant designed to answer frequently asked questions, collect useful information and support staff in their daily activities.The validation of the chatbot was carried out through systematic tests and questionnaires involving the target users. The results obtained highlighted the success of DIBot in satisfying most of the initial needs, demonstrating high performance in terms of usability, relevance of information and speed of response. However, areas of improvement emerged, particularly in error handling and the ability to understand complex inputs, indicating opportunities for further optimization and future developments.
