# Obsidian

> Build a connected notebook with files you control.

Obsidian keeps your notes as Markdown files on your own device. Link a thought to a related note, follow backlinks to see where it appears elsewhere, or look at the graph to explore connections across a collection. Canvas gives research, diagrams, and reference material a visual arrangement alongside the writing.

Plugins and themes let you adapt the app around a personal notebook, a research project, or a working knowledge base. The core app works offline. Optional Sync carries selected files and settings across devices and keeps revision history, while Publish turns chosen notes into a website that readers can explore through the links between them.
