About
Obsidian is a private, offline-first note-taking application that stores notes locally on your device in open file formats. It supports thousands of community plugins and themes, allowing users to customize their knowledge management workflow. Because it uses plain Markdown files, users retain full ownership of their data without vendor lock-in.
Problem
Most note-taking apps store data in proprietary formats on remote servers, leaving users dependent on the vendor and unable to access notes offline.
For
knowledge workers, writers, researchers, and anyone managing personal notes or a second brain
How it works
Obsidian reads and writes plain Markdown files stored locally on the user's device, with an extensible plugin system for added functionality.
