When notes, references and ideas accumulate, personal knowledge management software can help you organize them and trace their connections. Compared on organization model, graph view and backlinks, these tools also differ in offline access, import and export, and supported platforms. SiYuan, Obsidian and TheBrain are among the options to explore. Consider how you prefer to structure information and whether you need to move it between tools or access it offline.
