What is Obsidian?

Obsidian is a powerful note-taking application designed for personal knowledge management, journaling, and project organization. It distinguishes itself through its focus on privacy, flexibility, and long-term data ownership. All notes are stored locally on the user's device, ensuring quick, offline access and complete data control. No one, not even the developers, can access your notes.

Obsidian is highly customizable. Through the use of thousands of available plugins and themes, users can mold the application into the shape of their workflow. It prioritizes longevity, to keep your notes for a long time. The application uses open, non-proprietary file formats, ensuring that users are never locked in and their data remains accessible and usable for the long term.
