Obsidian is incredibly quick and adaptable. I appreciate that I have complete control over my data because all of my notes are kept locally in plain text.

I love the simplicity of it while having super flexibility and power. While it is so minimal and there is nothing to distract me, I can have a vast number of plugins that make the ecosystem suitable for my different workflows, such as journaling, YouTube script writing, mind mapping, database, session note-taking, learning processes, and... Also, with the power of tags and linking, it made a great structure for knowledge management.
