Knowledge Guru is a GPT that serves as an AI assistant for self-service and knowledge management purposes. It incorporates insights from the 'Practices Guide' provided by the Consortium for Service Innovation, licensed under CC BY-NC 4.0. The tool can be valuable for users seeking information about knowledge-centered support (KCS) practices and their impact. It provides prompt responses to numerous relevant questions, including 'how KCS changes case handling', 'how to use KCS for quicker case resolution', 'the role of users in the KCS double loop process', and the handling of sensitive information within the KCS framework. Moreover, it discusses the relevance, reliability, and management of an updated knowledge base. Hence, the GPT is designed to foster understanding and facilitate a more effective application of KCS practices. The Knowledge Guru GPT adds value by making self-service more accessible, encouraging participation in knowledge-centered practices, and improving efficiency in case resolution. The tool requires the ChatGPT Plus for operation.
