If you’ve spent more than five minutes in the "productivity" corner of the internet lately, you’ve probably seen a screenshot of a glowing, spider-web-looking map. It’s usually labeled as a "Second Brain" or a "Digital Garden."
Honestly? It looks like a NASA flight path or a conspiracy theorist’s basement wall. That’s Obsidian.
But behind the flashy graphs is a tool that is surprisingly simple—and also kind of frustratingly complex if you don't know why you're using it. People often ask: what is Obsidian good for? Is it just a glorified Notepad, or is it actually going to change how you think?
The short answer: it’s for anyone who is tired of their ideas dying in a forgotten folder.
The "Local-First" Philosophy: Why Your Notes Aren't Really Yours
Most apps you use today, like Notion or Evernote, keep your data on their servers. If their company goes bankrupt or their servers go down, your notes are essentially hostage.
Obsidian doesn't do that.
It lives on your hard drive. Your notes are just plain Markdown (.md) files sitting in a folder. You can open them with any text editor in the world. You could literally take your Obsidian folder, put it on a USB drive, and it would still work twenty years from now.
This is huge for privacy. Since there’s no central server reading your data, your private thoughts stay private. You own the files. It sounds like a small detail until you realize how much of our lives we outsource to "the cloud" without a backup plan.
Building a Web, Not a Filing Cabinet
The biggest thing Obsidian is good for is moving away from the "folder" mindset.
Think about how you usually organize files. You have a folder for "Work," one for "Personal," and maybe one for "Receipts." But what happens when you have a project that is both "Work" and "Personal"?
You have to choose. In the old way of thinking, an idea can only live in one place.

Obsidian uses bidirectional linking. You use [[Double Brackets]] to link one note to another. Suddenly, your notes aren't just sitting in a pile; they are talking to each other.
- You’re reading a book about psychology? Link it to your notes on marketing.
- Writing a grocery list? Link the "apples" to a recipe note for "Grandma’s Pie."
This creates a "Knowledge Graph." When you look at that spider-web visualization, you’re seeing the actual connections your brain has made between different topics. Over time, you start seeing patterns you never would have noticed in a rigid folder system.
Who Is Obsidian Actually For?
It isn't for everyone. If you just want to write a quick shopping list and delete it, keep using Apple Notes or Google Keep. Obsidian is overkill for that.
1. Researchers and Academics
This is probably the core fan base. If you’re writing a thesis or a book, you’re dealing with hundreds of sources. Obsidian is good for connecting those sources. You can use the Zotero integration to pull in your citations and then link them to your own original thoughts. It helps you avoid that "blank page" syndrome because you aren't starting from scratch; you’re starting from a web of pre-connected ideas.
2. Software Developers
Since the app is built on Markdown and supports community-made plugins, devs love it. You can store code snippets, track documentation, and even use "Dataview" (a plugin) to treat your notes like a database. You can write a query to show "all notes created in the last 3 days that have the tag #javascript."
3. Writers and Content Creators
Creating content is basically just remixing ideas. When you have a massive vault of notes, you don't "brainstorm"—you just look at your graph and see where the most connections are. That’s your next article.
The Plugin Rabbit Hole
You shouldn't try to master everything at once. The base app is quite bare-bones. The magic happens in the Community Plugins.
- Canvas: This is a literal infinite whiteboard where you can drag and drop your notes as cards and draw lines between them. It’s perfect for mapping out a story or a business plan.
- Daily Notes: Many users start their day here. It’s a scratchpad for whatever is on your mind. You can link to your tasks, your meetings, or that random shower thought you had.
- Excalidraw: If you like sketching or mind-mapping by hand, this plugin lets you draw right inside your vault.
One thing people get wrong: they think they need to install fifty plugins on day one. Don't. You’ll spend all your time "organizing" and zero time actually thinking. Start with the basics.
The Learning Curve (And Where People Fail)
Let’s be real: Obsidian has a bit of a learning curve.
It doesn't tell you how to organize your life. There are no templates by default. If you open it and expect it to look like a polished dashboard, you’ll be disappointed. It starts as a blank white (or dark) screen.
The biggest mistake people make is trying to build a "perfect system" before they have any notes. They spend weeks watching YouTube tutorials on the "Zettelkasten method" or "PARA," but their vault is empty.
Obsidian works best when it grows organically. You write. You link. You realize you need a better way to see your tasks, so then you find a plugin.
Is It Better Than Notion?
This is the "Android vs. iPhone" of the productivity world.
Notion is great for collaboration and pretty tables. If you’re running a team of ten people, use Notion. Obsidian is not a great collaboration tool because it's local.
But Notion is slow. It’s a "block" editor, which means every paragraph is its own little container. If you just want to write, Notion can feel clunky. Obsidian is fast. It’s essentially a high-powered text editor. It opens instantly. It works offline.
If you value speed and privacy over "pretty" and "collaborative," Obsidian wins every time.
Actionable Steps to Get Started
If you’re ready to see what the hype is about, don't overthink it.
- Download it and create a "Vault." Just pick a folder on your computer.
- Turn on the "Daily Notes" core plugin. This gives you a place to dump thoughts every day without worrying about where they "belong."
- Start linking. Every time you write a word that feels like a "topic" (e.g., Marketing, Fitness, Ideas), put it in
[[brackets]]. - Ignore the Graph View for a month. It’s fun to look at, but it’s useless until you have at least 50-100 notes.
- Check out the "Dataview" or "Templater" plugins only once you feel like the manual work is becoming a chore.
Obsidian is ultimately a tool for long-term thinking. It’s not about what you wrote today; it’s about how what you wrote today will help you three years from now when you’re trying to remember that one specific insight. It’s a slow-burn productivity tool. But once it clicks, it’s hard to imagine going back to a regular filing cabinet.
