Getting started

Frequently asked questions

Which file types are supported?

Epic MD Viewer opens .md, .markdown, .mdx, .mdown, .mkd, and .mdwn files.

Can I edit files in the app?

No. Epic MD Viewer is a read-only viewer — it never modifies your files. Edit in your favorite editor and watch the preview update live.

Does it support Mermaid diagrams and code highlighting?

Yes. Fenced code blocks are syntax-highlighted, and mermaid code blocks render as diagrams automatically.

My file isn't updating when I save it.

Live reload watches the file on disk. If updates stop, close and reopen the file. If the problem persists, email us with your macOS version and a sample file.

Does the app collect any data or require a network connection?

No. Epic MD Viewer works fully offline, makes no network requests, and collects no personal data. See the Privacy Policy for details.

How do I request a feature or report a bug?
