- I’ve made no secret of my love for Obsidian, the free-form, loosely-organized, markdown-based notetaking tool. I use it for everything. I use it to organize work, I use it for drafting blog posts, and I use it when I need to get something out of my head. One of the super-powers of Obsidian and the Zettlekasten notetaking philosophy is the concept of writing stuff down now and organizing it later. Obsidian provides many different views to explore and navigate between notes.
