Obsidian (Winner for now)​

Why I use it?​

• Easy to sync notes across multiple devices.
• So fast compared to other alternatives.
• Uses .md files. If something goes wrong with Obsidian, I would be able to switch to another app.

Disadvantages​

• It isn't open source.
  • If they close the app, you need to handle tags in a different app again. (You don't if you use markdown links.)
• You are going to feel like somebody is reading your notes.
  • I don't store sensitive information in Obsidian to solve this problem and I am not think about it so much which I don't want to waste my time on it. I couldn't find any open source alternative that is as good as Obsidian therefore I need to use it.
  • They say they don't, but how can we trust them if we don't know the source? Maybe reverse engineering, but I don't know how to do that, and I didn't find any information about Obsidian. Even if we do that and find out they don't read, we can't do that every time. That means they can change the code, and we need to reverse engineer continually to find out what is going on. Maybe closing the network for Obsidian can work, but that can be advanced to create a sandbox and close the network. Also, this would lead us to not be able to use extensions, which include a bunch of useful extensions.

As a student, I can say that I used to think piracy was the solution until I learned about open source and free alternatives (see https://alternativeto.net/) and that pirated applications could contain viruses. Generally, hacker groups cracking applications in pirated software tend to avoid adding viruses so as not to tarnish their reputation.
