# Obsidian

Obsidian is a note-taking app that stores notes as plain Markdown files on the user's device, so they can be read offline. Users link notes to each other, view the links as a graph, and arrange ideas on an infinite canvas. Community plugins extend the app, and optional paid add-ons provide end-to-end encrypted Sync and website Publishing.
