The Note Codes plugin assigns unique 4 character codes to every note in our vault, making it easy to reference and retrieve notes quickly. These codes appear in the status bar on desktop and in the metadata sidebar on mobile devices and can be clicked or right clicked for actions like searching, copying or generating an obsidian:// URL for the note. A built in search function lets you find notes directly by their code using a quick switcher, while command palette actions extend this workflow with one click copying of codes or code URLs. The codes are derived from the note's path using a hashing scheme, ensuring consistency and uniqueness across your vault.
