Part 2. A Deep Dive into the Details

After seeing the comparison table, it is time to learn in depth about what abilities and features each of these tools holds.

A. Note-Taking Style & Workflow

  • Notion: It is designed around clean and structured pages. You can mix text with images, tables, checklists, and embedded web content. This makes it great for gradual workflows like project outlines.
  • Obsidian: This tool uses plain text files in Markdown. Each note is a simple text file that you can organise into folders or tag. With the help of this setup, you have the flexibility and control to connect ideas.
  • Roam: Focuses on daily notes and blocks, which are small pieces of text you can link anywhere. It is built for capturing thoughts as they come and exploring connections throughout your note graph

B. Linking & Graph-Based Thinking

  • Roam: This is the pioneer of bi-directional links, and it lets you easily see where ideas connect. In the form of a “knowledge graph,” it visualises note connections,  which helps you spot patterns and themes.
  • Obsidian: It also supports bi-directional linking and graph visuals, but everything is stored locally. However, you can enhance the experience using community-created plugins
  • Notion: Though it offers basic backlinks, they tend to feel slower and more limited. In this tool, the graph experience is weaker compared to other similar tools.

C. Customization & Extendability

  • Obsidian: Here, you will enjoy a strong customisation of settings through plugins and themes. The community has built everything from calendar widgets to Kanban boards, which is great if you like to tweak your tools
  • Notion: As this tool provides ready-made templates and connects to many other apps, it makes it easy to build workflows quickly. Users can enjoy over 7,000 integrations that are supported by this program.
  • Roam: This tool has fewer built-in extensions as compared to any other similar one. Additionally, advanced users can add functionality via APIs, but it is less user-friendly than the others.

Part 3. Use Case Scenarios 

After a detailed exploration of each tool, here are the use case scenarios for each tool. These showcase how different users can apply them according to their needs.

Notion – Team & Project Management

An application that shines in organising collaborative work. Most of the small agencies and remote teams use shared dashboards for projects and event planning. For instance, a design agency manages multiple client projects and meeting notes all in one workspace 

It’s also popular for personal use, such as couples can implement it as a “plan hub” for chores. Also, they can use it for date night ideas and family reminders. In this way, it can boost their communication and daily harmony.

Obsidian – Personal Knowledge & Creative Workflow

This tool is a favorite among writers and lifelong learners who just never get tired of learning. Freelancers use it to track article ideas and draft directly in Markdown. Moreover, academics build interconnected research notes to spark new insights by visualizing idea connections.

Roam – Exploratory Journaling & Idea Linking

It provides users with a powerful source who are into thinking visually and exploring connections. It is commonly used for daily journaling, habit tracking, and automatic note linking. Researchers and students appreciate the “scratchpad” style of daily notes, which they later link into their long-term knowledge base.
