What Obsidian Does
Obsidian is a note-taking app that stores your notes as local markdown files on your device. This means you own your data, can use any sync service, and your notes will outlive the app. The focus is on building a personal knowledge base with bidirectional links.
The app has become the favorite of "PKM" (personal knowledge management) enthusiasts who want to connect ideas and build long-term knowledge systems.
Key Features
Local Files: Your notes are plain markdown files stored on your computer. No proprietary format, no cloud lock-in. Use any sync service (Dropbox, iCloud, git) or Obsidian's paid sync.
Bidirectional Links: Link between notes with [[wiki-style]] links. See all notes that link to the current note in the backlinks panel.
Graph View: Visualize how your notes connect in an interactive graph. Useful for discovering unexpected connections.
Plugin Ecosystem: Over 1,000 community plugins for everything from daily notes to kanban boards to AI assistance.
Pricing
Obsidian is free for personal use. You own your files regardless. Paid add-ons include Obsidian Sync (encrypted sync across devices) and Obsidian Publish (publish notes as a website). Commercial use requires a license.
