What is Obsidian?

Obsidian is a note-taking app for personal notes, journaling, knowledge bases, and project management. It stores notes privately on your device and lets you access them offline, without giving Obsidian access to their contents. Thousands of plugins and themes let you customize the app to fit your way of thinking. It uses open file formats so you retain ownership of your data over the long term. Its tools help you organize ideas across personal writing, knowledge collections, and projects.
