Obsidian is a private, flexible note-taking app that stores notes locally as plain text Markdown files and adapts to the way you think.
What is Obsidian?
Obsidian is a local-first note-taking application that saves notes as plain text Markdown files on your device. It takes simple Markdown notes as input and produces a richly linked knowledge base with an interactive graph view. The app is available on Linux (AppImage), macOS, Windows, iOS, and Android, and is developed by Obsidian MD.
What makes Obsidian stand out?
- Links — Create bidirectional connections between any notes using double brackets, building a personal wiki with backlinks and unlinked mentions.
- Graph — Visualize all note connections as an interactive node graph, revealing hidden patterns and clusters.
- Canvas — An infinite whiteboard workspace for brainstorming, diagramming, and laying out ideas using embedded notes, images, and web content.
- Plugins — Thousands of community plugins (e.g., Calendar, Kanban, Dataview) via an open API, allowing deep customization of the editor and workflow.
- Sync — End-to-end encrypted sync across devices with selective file syncing (images, audio, video, PDFs) and one year of version history per note.
- Publish — Turn any vault into an online wiki or digital garden with custom domains, password protection, and SEO optimization, all editable from within the app.
Who is it for?
- Knowledge workers — Build a personal knowledge base by linking ideas, references, and projects.
- Researchers and academics — Organize literature notes, quotes, and citations with tags and links, visualized in the graph.
- Project managers — Manage tasks, kanban boards, and project plans using plugins like Tasks and Kanban.
