What is Obsidian?

Obsidian is for people who think in connections. It's a note-taking app that treats your notes like a web of knowledge, helping you discover relationships between ideas through backlinks and graph views. Whether you're building a personal knowledge base, writing a book, or managing research, Obsidian makes your notes feel alive and interconnected. It's the tool that proves your second brain doesn't have to live in the cloud—it can live on your computer, under your control.
