Discover the unique and powerful advanced features that make Obsidian stand out. These features are designed to enhance your experience and provide added functionality.
Obsidian stores all your notes as plain-text Markdown files on your device. This design ensures total control, easy backups, and future-proof access. There’s no vendor lock-in, so your notes remain yours even if the app changes or disappears. This foundation is crucial for privacy and portability.
Every note can link to others, and Obsidian automatically tracks backlinks to show which notes reference the current one. This creates a rich, interactive web of connections. It turns your notes into a dynamic knowledge graph that grows organically with your ideas.
Obsidian’s graph view renders your entire vault as a dynamic, zoomable map of notes and links. It helps you identify clusters, discover hidden relationships, and better understand your knowledge structure. This visual insight is invaluable for complex projects and research.
Thousands of community-created plugins let you tailor Obsidian to your needs—from task boards and calendars to AI assistants and advanced queries. This vibrant ecosystem constantly grows, transforming Obsidian into more than just a note-taking app.
The Canvas feature offers a flexible workspace where you can freely arrange notes, images, and media. This spatial layout supports brainstorming and visual mapping beyond linear notes, enhancing creativity and idea organization.
Obsidian offers an optional, end-to-end encrypted sync service that keeps your vault updated across devices. It protects your privacy, offers version history, and provides seamless access whether on desktop or mobile.
