A Personal Knowledge Base (PKB) is a system that individuals use to organize and store information, ideas, and insights that are relevant to their personal or professional lives. It can include notes, articles, links, and other resources that help users retain and retrieve knowledge efficiently. PKBs can be digital or physical, and they often utilize software tools or applications designed for note-taking and information management. The primary goal of a PKB is to enhance learning and productivity by making information easily accessible. By categorizing and linking related topics, such as projects, research, or personal interests, users can create a structured repository of knowledge that supports their ongoing development and decision-making processes.
