What Obsidian does
Obsidian is a note-taking application designed to help users build a connected knowledge base. It organises notes as individual files on your local device and supports connections between notes, visualised as a graph. Built for knowledge workers, researchers, and anyone managing large amounts of interrelated information, it stands apart from cloud-only alternatives by keeping data local and giving users full control over their files. Obsidian supports flexible organisation, fast linking between notes, and extensibility through plugins. This tool fits those who value privacy, custom workflows, and want to use markdown for their notes.
