Obsidian

1. What is Obsidian?

Positioning: A powerful, local-first knowledge base that operates on plain text Markdown files, designed for personal knowledge management, note-taking, and information organization using a unique graph-based linking approach.

Functional Panorama: Covers note creation and editing, bidirectional linking, an interactive graph view for visualizing connections, extensive customizability via themes and a rich plugin ecosystem, and optional first-party or third-party synchronization capabilities.

2. Obsidian’s Use Cases

• Personal Knowledge Management: Users can link disparate ideas, create a “second brain,” and develop complex, interconnected knowledge networks for holistic understanding.
• Academic Research & Study: Researchers and students can manage notes, literature reviews, connect concepts across various sources, and outline papers.
• Writing & Content Creation: Authors, bloggers, and content creators can outline, draft, and connect different pieces of content, building a robust and interlinked content repository.
• Project & Task Management: Individuals can break down projects into linked notes, track tasks, and manage workflows using Markdown files, often enhanced with community plugins.
• Programming & Documentation: Developers and engineers can document code, manage project-specific notes, and link technical concepts or design decisions.

3. Obsidian’s Key Features

• Supports local Markdown files for notes, ensuring data ownership, offline access, and future-proofing.
• Bidirectional linking and backlinking for seamless navigation and discovery of interconnected knowledge.
• Interactive Graph View to visually explore and understand the relationships between notes.
• Highly extensible plugin API that supports both official and a vibrant community-driven ecosystem of hundreds of plugins.
• Customizable interface with various themes and CSS snippets to tailor the appearance.
• Official “Canvas” feature, significantly expanded in late 2023, offering a free-form visual workspace for notes and ideas.
• Improved Live Preview editing experience with better cursor positioning and WYSIWYG editing, continuously refined in updates.
• Users frequently recommend the “Community Plugins” ecosystem for extending functionality, particularly “Dataview” for dynamic queries and “Excalidraw” for embedded diagrams.

4. How to Use Obsidian?

1. Download and install the Obsidian application for your operating system (Windows, macOS, Linux, iOS, Android).
2. Create a new “vault,” which is a local folder on your computer/device where all your Markdown notes will be stored.
3. Create new notes using the “New note” button or by typing Ctrl/Cmd + N.
4. Link notes using the [[Note Name]] syntax; hover over a link to preview its content, or click to navigate directly.
5. Explore connections between your notes by clicking the Graph View icon in the left sidebar.

Pro Tips:
– Typing [[ immediately triggers an auto-completion list for existing notes or allows you to create a new one on the fly.
– Use the ! prefix to embed images, PDFs, or other notes directly into your current note.
– Access the “Community Plugins” section in settings to explore and enable powerful features like daily notes, task management, or advanced data querying.
– Leverage “Daily Notes” to create a fresh note for each day, providing a structured journal or a dedicated space for daily thoughts and tasks.

5. Obsidian’s Pricing & Access

• Free tier: The core Obsidian application is entirely free for personal use, including all fundamental note-taking, linking, and customization features.
• Obsidian Sync: An official, end-to-end encrypted synchronization service across devices, priced at $10/month (or $96/year when billed annually).
• Obsidian Publish: Allows users to publish selected notes as a public website, starting at $20/month for one site (or $192/year when billed annually).
• Catalyst License: A one-time payment ($25+ tiers) for early access to insider builds and to provide financial support for Obsidian’s development.
• Compared to cloud-based knowledge management tools, Obsidian’s free core application offers significant cost savings for users prioritizing local data control. No widespread limited-time offers were reported for its paid services in early 2024; pricing tends to be stable.
• Tier Differences: Free users typically manage their own sync solutions. Obsidian Sync provides built-in version history, encrypted storage, and seamless mobile synchronization. Obsidian Publish streamlines the process of sharing notes publicly without requiring external web hosting setup.
