The Science of Obsidian

Obsidian

a Markdown file reader.

a note-taking app.

a knowledge base.

your second brain.

Obsidian is a Markdown file reader. It sits on top of any relevant files in a designated folder or vault and enables users to write, edit and interlink their notes. It's built for taking notes quickly and adding bidirectional links. You can use it to build a personal wiki or Zettelkästen.

Obsidian is a powerful and extensible knowledge base that works on top of your local folder of plain text files.

The human brain is non-linear: we jump from idea to idea, all the time. Your second brain should work the same.

In Obsidian, making and following connections is frictionless. Tend to your notes like a gardener; at the end of the day, sit back and marvel at your own knowledge graph.

Note-taking is incredibly personal. Tried every app, but something always irks you? You deserve better.

For those who can't custom-build a solution for themselves, Obsidian is as close as you can get, with plugins, themes, and custom CSS at your disposal.

In our age when cloud services can shut down, get bought, or change privacy policy any day, the last thing you want is proprietary format and data lock-in.

With Obsidian, your data sits in a local folder. Never leave your life's work held hostage in the cloud again.
