Obsidian is a Second Brain and note taking app. It is a powerful and extensible knowledge base that works on top of your local folder of plain text files.

Obsidian is a wrapper around your folders and Markdown files, including one single folder called .obsidian in your root. That’s it! In case you like to use another editor such as vim, VSCode or just any other  Text Editor you might have, open all your files individually. Or, in case you want to open all notes in one go, use open Obsidian.

# Price and Features

Let’s get this out of the way, Obsidian is entirely free! You can add two  paid features, 1. if you want to use their integrated sync tool or 2. if you want to share your notes, including the fancy graph and outline view.

But yeah, as it is plain text stored on your hard drive, you can use Dropbox, Google Drive or any other sync tool! As I’m using  Sync.com with end-to-end encryption for all my files, it does not work nicely on my mobile. That’s why I added Obsidian Sync. I could have added it to Dropbox, but I didn’t want to give them my most private notes.

If you want to check out all the other features, see the complete list at  Obsidian.md or find more customisation with  25 core and  329 community plugins, 60+ themes, plus custom styling, you can tweak Obsidian to work and look exactly how you want it.

Some community plugins do a single thing extremely well, like  Calendar and  Kanban. Others unlock endless possibilities:  Dataview and  Templater are great examples.

# Why Obsidian

# Plugins

super explainer:

I struggled with that as well. And I noticed over time, I automatically linked less. I like the example. Over time, you will change and update your notes and also feel when to use a connection and when it’s obvious.

Also, to relax your brain, e.g., I wanted to link everything to Obsidian as it was the root for many things I’m writing. But even though you do not link it, you will still see the connections in Unlinked mentions. This helps me not to think I will lose the note.

Usually every note should at least be linked to one note. I also do that with my template that has an Origin and References. If I didn’t come up with a link through the text, I make sure that I at least link it to one reference that I think relates most, so it’s more likely to come up months or years down the line. Most of the time, the link also comes from Origin, as it’s usually a person or a blog that I already have in my Second Brain.

Here is the footer I add automatically to each note:

Created <% tp.date.now(&

Sometimes, I even create an intermediate new note to the next, as it helps me to find and categorize my thoughts better.

But again, with time, you will figure that out; these come naturally. Especially when you check backlinks to a note, and you have 100s of them, they get a little useless. Therefore, you naturally add fewer in the future.
