Obsidian is a Markdown Editor and Reader that can turn a folder of Markdown files into a very powerful knowledge base. The concept is that Obsidian is designed to work with a local folder on your computer which is also capable of syncing with cloud based providers like Dropbox. Essentially this leads to a scenario where you are in control of all of your data as opposed to having it on a 3rd party server. The Markdown files are stored on your local computer and you don't have to share them unless you want to.
Obsidian is available for Windows, Linux, and macOS. As of writing they have an iOS and Android version which are in private beta. You can download Obsidian here https://obsidian.md/
The concept for Building A Second Brain is that as we go through life we have many thoughts, ideas, reflections as well as different networking connections. These are things that we attain as we go through life. So in essence Building A Second Brain is the methodology for turning all of that raw data into a compact form that we can use to categorize the information into a library. Another way to look at it is that you are putting together a simple plan which acts as a database for all of the knowledge that you gain and the sources they came from.
I use the Obsidian Desktop App when working on a computer. Obsidian uses a concept known as backlinks. This is how you link other notes together. It is a lot like tagging which Obsidian can do too!
This is what it looks like in Markdown.

When you have created a lot of backlinks you can go to the graph view and see how they all relate to each other. If you put your mouse cursor on the circles it will show you the link tree for the notes. If you click on the circle then it will take you to the note. You can also filter by tags as well as other parameters.
When working on mobile I use a different setup. This is because the Obsidian Mobile Apps are still in private beta. I am an Android user so I will be posting links for the apps that I use. There are alternatives on iOS if you search for them.
