The culture, economics, political and social spheres directly depend on the abilities and intelligence of people in a country. For any person or organization, knowledge is a strategic asset. The task of each person is to create such conditions so that the necessary knowledge and information are easily available at all time. The paper discusses the ways of storing knowledge, the knowledge management methodology Zettelkasten, the software for storing and managing knowledge TheBrain, Roam Research, Obsidian. In most cases, a hierarchical structure is not suitable for storing knowledge, you often need to link notes to several different topics at the same time.
