Obsidian

Obsidian turns a local folder of plain text Markdown files into a powerful knowledge base that works exactly the way you want. It acts as a second brain, storing your thoughts and notes securely on your device, always available when you need them.

With a customizable toolbar and pull-down quick actions, you can navigate and edit notes effortlessly. The graph view visually maps connections between your ideas, helping you see patterns and relationships that might otherwise go unnoticed. You can also share content to and from Obsidian, making it easy to capture information from other apps.

For those who want more, community plugins and themes let you tailor the experience to your liking. On tablets, sidebar pinning provides a comfortable layout for multitasking. Whether you are a student, researcher, or professional, Obsidian offers a flexible and private space for your knowledge.
