About Obsidian

Obsidian is a powerful and extensible knowledge base that works on top of a local folder of plain text Markdown files. It's built around the idea of a "second brain" — a personal knowledge management system that grows with you.

Unlike cloud-based tools, Obsidian stores all your notes as plain Markdown files on your own device. This means you always own your data, it works completely offline, and your notes are compatible with any text editor.

Key Highlights

• Bidirectional links create a network of connected notes
• Graph view visualizes relationships between your notes
• 1000+ community plugins for every workflow
• All data stored as plain Markdown files — no lock-in
• Powerful search across your entire vault
• Canvas feature for visual note organization
