Obsidian is more than a note app—it’s a system for building your own knowledge base with plain text markdown files. Here is why: Every note can link to others, creating a web of connected ideas. This linking helps you see relationships and patterns between topics. Let’s break it down. Obsidian stores notes locally, which means you control your files. Sync is available as a paid add-on, but you can also use Dropbox or Git if you prefer. The plugin ecosystem is another strength, offering features like spaced repetition, kanban boards, or daily notes. Writers, researchers, and students often use Obsidian as a personal wiki or knowledge map. Next steps: Start with a single folder of markdown notes. Add links between related notes, then open the graph view to see your knowledge take shape. Takeaway: Obsidian is best for people who want a connected, long-term system for knowledge management.
