Offline, always
Zero network calls by design. Your documents never leave your Mac, so confidential files stay confidential.
macOS 14+ · Apple Silicon
mdNotch turns PDF, Word, Excel, PowerPoint and seven other formats into
Markdown — on your clipboard and saved as a .md next to the
original. No terminal, no Python install, not a single network call.
Nothing on screen until a file comes near the top edge.
How it works
Pull any document toward the top of your screen. The drop zone opens under the notch before your cursor gets there.
The rim lights up while the conversion runs — locally, in a bundled binary, with no request leaving the machine.
A green check says Copied. The Markdown is on your clipboard
and a .md file sits next to the original.
Eleven formats
A .zip is walked recursively and comes back as one concatenated
.md. Anything outside this list is refused up front with a plain
Unsupported format — images and audio are deliberately out, they'd
need an API key or a second binary.
What it does
Zero network calls by design. Your documents never leave your Mac, so confidential files stay confidential.
The converter ships frozen inside the app. No Python, no Homebrew, no
command line — drag the .app out of the DMG and you're done.
Several files at once: one .md per file, plus a single
clipboard payload separated by # filename. One broken file
fails alone — the rest still convert.
No Dock icon, no window, not one stolen pixel. A menu-bar item holds Settings, Launch at login and Quit; a gear appears when you hover the notch.
Next to the source file by default, or one fixed folder for everything.
A name clash gets a -1 suffix — never an overwrite, never a
dialog in the middle of your gesture.
The notch is only a visual anchor. On an iMac, a Mac mini or an external display the same zone drops from the top-center of the screen.
Drag the app out of the DMG into Applications, and the next document you drag upward comes back as Markdown.
