What is Markdown Viewer for Obsidian?
Obsidian stores every note as a plain Markdown file, which means an Obsidian vault is really a folder of .md files. That is great for portability — and it means you can inspect any note outside Obsidian by rendering its Markdown in a viewer. This is handy when you are on a machine without Obsidian, sharing a note with someone who does not use the app, or checking how a note will look before converting it for publishing.
Common Uses for Markdown Viewer for Obsidian
- Reading an Obsidian note on a computer without the app installed
- Checking how a note renders before publishing it as a blog post
- Sharing a note's content with someone who does not use Obsidian
- Reviewing exported vault notes as plain Markdown
The portability advantage of plain Markdown notes
Because Obsidian keeps notes as Markdown rather than a proprietary database, your vault is not locked to the app. Any tool that reads Markdown can read your notes, from a text editor to a static site generator to a browser viewer. This is the practical difference between storing knowledge in Markdown and storing it in a cloud note service where the format is opaque and the export is lossy.
Obsidian syntax that is not Markdown
Obsidian adds several extensions on top of Markdown: wikilinks, callouts, embedded notes and query blocks. These are processed by the app, not by the Markdown spec, so a generic viewer shows them literally. When you want a note to render the same everywhere, stick to standard Markdown syntax and treat Obsidian's extras as convenience features for use inside the app.
