Consider you have an excellent idea for a blog post, video, or podcast. You get to work; before long, you have a few headings and random notes jotted down. What happens next? Life gets busy, and your notes are soon forgotten. Weeks or months later, you stumble across the remnants of your once-ambitious project.

They’re disorganized, incomplete, and make no sense out of context. If only you had a better way to manage your notes. This is where Second Brain Code like Obsidian and Roam Research shine. Both are powerful tools for jotting down ideas and organizing them in a way that lets you quickly pick up where you left off.

What is Obsidian?

Obsidian is a note-taking app that uses Markdown files to help you build a networked knowledge base. It provides a customizable environment for creating, linking, and organizing notes, making retrieval intuitive and efficient.

Create Links to Connect Notes

Obsidian’s linking feature allows for the creation of direct connections between notes, enabling you to reference and navigate related content easily. You can keep track of text passages by linking them together. For example, a researcher could tag notes to organize their findings and create connections to revisit later. You can link to other notes and revisit ideas as you write, creating a web of interconnected information that helps eliminate redundancies and organize your knowledge. It’s like reference links in a research paper but on a larger scale.

Visualize Your Notes with Graph View

The Graph view in Obsidian provides a visual map of your notes and their interconnections, offering a unique perspective on your knowledge base. It’s a web of connected notes linked together. This is great for seeing relationships, organizing, and mapping ideas for brainstorming. The interactive maps highlight relationships for each note when you hover with your mouse.

Organize Notes with Canvas

Canvas in Obsidian is a flexible space where users can visually organize their thoughts and notes. The interface is similar to Figma, where you can arrange text boxes and images any way you conceive. You can visually organize and connect your notes in any layout. Teams can manipulate audio, video, photos, and PDFs in Canvas, use the workspace as work views for notes, and nest Canvas views inside Canvas.

Extend Functionality with Plugins

Obsidian supports a wide range of community-developed plugins that extend the app's functionality. There are over 1,000 plugins, and there’s quite a variety. They have plugins for exporting, working with HTML, software integrations, AI assistants, annotating, and more.

Sync Notes Across Devices with Obsidian Sync

Obsidian Sync is a premium service that offers end-to-end encrypted synchronization of your notes across devices. It ensures that your data is securely updated and accessible, whether you are working from your desktop, laptop, or mobile device.

Publish Notes Online with Obsidian Publish

With Obsidian Publish, users can share their notes and knowledge bases. This service transforms your Obsidian vault into a publicly accessible website where you can share ideas and information on a personal or professional platform.

Roam Research vs Obsidian Detailed Comparison

Core Philosophy and Approach: Understanding the Fundamental Differences Between Roam Research and Obsidian

Roam Research centers on networked thought, mimicking how the human brain connects ideas. It emphasizes a non-linear note-taking style that allows users to link ideas dynamically instead of organizing them hierarchically. The system is designed to be fluid and organic, helping users make unexpected connections between concepts.

On the other hand, Obsidian is designed as a local-first personal knowledge base where all notes are stored in plain text Markdown files. It is more structured and customizable, making it ideal for users who prefer a systematic way to build a digital second brain. It functions more like a file-based knowledge management system than Roam’s block-based approach.

Data Storage and Privacy: Who Owns Your Data?

Roam Research stores all notes on the cloud, requiring an internet connection for access. This means users do not fully own their data, and there could be potential privacy concerns. Collaboration is easier since everything is stored online.

On the other hand, Obsidian stores notes locally on the user’s device, ensuring complete control over data. Users can opt for third-party sync solutions (such as iCloud, Google Drive, or Obsidian’s paid sync service). Since files are in the Markdown format, they can be backed up quickly and used in other applications.

Linking and Note Connections: The Backbone of Note-Taking Software

Roam Research uses bidirectional linking as a core feature, allowing users to reference notes dynamically. Every note is structured as a document of interlinked blocks rather than a standalone file. A graph view provides a visual network of connected notes, making it easier to explore relationships between ideas.

Obsidian also supports bidirectional linking but focuses more on linking entire notes than content blocks. The graph view allows users to see connections between files, though some users find it less fluid than Roam’s approach. Users must structure their linking manually instead of relying on Roam’s more automatic linking system.

User Interface and Ease of Use: Which Tool Is Easier to Navigate?

Roam Research features an outliner-based interface, where every note consists of bullet points that can be nested and collapsed. This suits it best for daily journaling, research, and non-linear thinking. However, it lacks a traditional file system, which some users might find limiting.

Obsidian offers a more conventional note-taking interface, where each note is a separate file. Users can access a sidebar to browse folders and files, making it easier to navigate larger knowledge bases. Markdown formatting makes it great for writing long-form content.

Customization and Plugins: Go Beyond the Basics

Roam Research has limited customization options and mainly relies on CSS tweaks. It has no official plugin system, though there are some community-made extensions. The core experience is streamlined but not highly flexible.

Obsidian boasts extensive customization options via themes and settings. A robust plugin ecosystem allows users to add features like tables, kanban boards, calendar views, and AI integration. Users can modify Markdown files with scripts, making it a more developer-friendly option.

Collaboration and Sharing: Working Together to Improve Your Notes

Roam Research supports multi-user collaboration, making it ideal for teams. Users can share databases and work together in real time. However, it does not have granular access controls like Google Docs.

Obsidian is primarily a single-user application with no built-in collaboration. Users can manually sync files, but Roam's cloud-based approach is not as smooth. Collaboration is possible via third-party solutions (e.g., Dropbox or Obsidian Sync).

Task and Project Management: Which Application Does It Better?

Roam Research includes built-in task management features, such as TODO lists and daily journaling. Users can tag tasks and track progress over time, which makes it great for goal tracking and productivity workflows.

Obsidian lacks native task management but supports it through plugins (e.g., the Tasks plugin). It can be integrated with third-party task managers like Todoist or Things 3. Overall, it works better for static note-taking rather than dynamic task tracking.

Pricing: Calculating the Cost of Each Application

Roam Research operates on a subscription-based pricing model. It costs $15/month or $165/year, making it one of the more expensive note-taking tools. Obsidian is free for personal use. Obsidian Sync ($8/month) is optional for cloud storage. There’s also a one-time purchase for commercial use ($50+ per user/year).

You can quickly add a formula, a table, or an image to the same note.

I appreciate the fluidity of this approach—it feels like a natural note-taking and journaling experience. OneNote templates provide a convenient starting point for organizing your notes, whether planning a project, keeping track of tasks, or journaling. Our team tested its relatively smooth collaboration features. You can work in tandem (on grocery lists, party shopping, or work to-dos) with family members or your team, and your notes get updated in real time. The interconnectedness of the Microsoft suite always makes it its USP and its limitation—it depends on who you ask.

It’s still the most straightforward app if you work within the Apple realm—summon it anytime on your Mac from the bottom right corner, and it pops up earnestly. Syncing is mostly great; copying something on the phone and pasting it on your desktop is magic. The little things that boost the experience. Ask more of the app, and you’ll be disappointed.

Moving the text around, formatting, and indenting are not easy. Any more advanced use cases are not supported. You can save multiple types of content, including images, web links, handwritten notes, maps, PDFs, and sketches. I prefer Apple Notes’s scanning feature to scanning documents directly from my iPhone—there is no need for third-party scanners! The documents are saved directly within Notes as PDFs.

Pros
