I built an online viewer and editor for .md files where the file stays on your machine. Free to use and code is available under MIT License here: <a href="https:&#x2F;&#x2F;github.com&#x2F;hattray&#x2F;markdown-editor" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;hattray&#x2F;markdown-editor</a><p>You can also install it as a Chrome&#x2F;Edge app so that it works for files on your desktop by double-clicking.<p>Supports standard .md files with formatting, syntax-highlighting for code, table of contents, Mermaid diagrams, LaTeX via KaTex. Also supports exporting to .html, .pdf and .png.<p>Please give it a try and share your feedback for improvements.
