Benefits of Obsidian

Canonical version: Benefits of Obsidian.

Obsidian is a powerful note-taking and knowledge-management app that focuses on local, plain-text files and interconnected ideas. Unlike many other tools, it prioritizes longevity, privacy, and linking your notes together.

Obsidian is truly unique:

• Free for personal and professional use
• Extremely fast
• Cross-platform (Windows, Linux, MacOS)
• Local plain-text Markdown files make it easy to integrate with AI tools (scripts, LLMs) for processing and generating notes; see Use cases for AI and local knowledge bases
• Mobile support
  • Gets faster with each update
  • Widgets and quick capture on iOS (support for Apple Shortcuts)
• Data stored locally
  • You own the data (great for security and privacy)
  • Works offline
• No telemetry (no data collection or analytics — your usage stays on your device)
• Powerful features for Knowledge Management (KM); capturing, organizing, and connecting information:
  • Links (clickable cross-references between notes)
  • Backlinks (see which notes link to the current one)
  • Tags and nested tags
  • Global and local graph views (interactive maps of how your notes connect)
  • Automatic outlines
  • Embedding, aka Transclusion (display content from one note inside another)
  • Support for structured data (properties on notes)
  • Built-in databases (called Obsidian Bases) leveraging the note properties (similar to spreadsheet-style tables in your notes)
  • Support for infinite canvas (open specification: JSON Canvas)
• Markdown
  • Plain text
  • De-facto standard
  • Open and portable data format
  • Supported by all text editors

    • For instance with the help of Obsidian AI Skills by Steph Ango and my Obsidian Plugin Template)
  • Assign hotkeys for anything
• Large, active community (a major advantage for plugins, support, and themes)
• Various ways to publish and sync notes (e.g., Obsidian Publish, Obsidian Sync, Syncthing, and various additional solutions built by the community)
