What is Obsidian?
Obsidian is a local-first knowledge management and note-taking application designed for building interconnected personal knowledge bases. Notes are stored as plain Markdown files in a local vault, giving users direct ownership and access to their data. Obsidian provides backlinks, graph visualization, tags, properties, search, templates, plugins, themes, canvas-based organization, and extensive customization. Its community plugin ecosystem allows users to extend the application for tasks such as project management, research, writing, task tracking, and personal knowledge management. Optional Obsidian Sync provides encrypted synchronization between devices, while Obsidian Publish enables users to publish notes as websites.
