What it does
Open. Read. Edit. Done.
Renders instantly
Double-click any .md — CommonMark + GitHub flavour, in a clean reading theme that follows light/dark.
Quick Look preview
Tap space on any .md in Finder and it renders right there — the same theme, no need to open the app.
Edit & save
Press ⌘E to edit the source, ⌘S to save. It never silently overwrites a file that changed underneath you.
Images just work
Pictures next to your note render in place — resolved safely from the note's own folder.
Your default .md app
Offers to open every Markdown file on your Mac, so they stop opening as raw text.
The promise
Local and yours.
No cloud, account or proprietary library. Your files remain plain .md in the folders you already use. PX7 Markdown Viewer is free.
