munkeln (German, v.) — to whisper in secret
Whispers from the notch.
Munkel is ephemeral messaging for macOS: end-to-end encrypted notes from your favorite people, sliding elegantly out of the MacBook notch — and gone moments later. No accounts. No history. No trace.

One code is everything.
A group is born from a shared, human-readable code. The code is the room and the key — it never touches a server.

Anything memorable. The sillier, the better.
Tell your friends
Over coffee, ideally — not over the internet.
Whisper away
Everyone who knows the code is in. Forget the code, and the group never existed.
Built to forget.
Every architectural decision serves the same goal: your conversations exist only in the moment — and only on your screens.
Ephemeral by design
Messages exist only in the moment they arrive. The relay stores nothing — friends who are offline simply miss the whisper, like in real life.
End-to-end encrypted
AES-256-GCM with keys derived on your devices. The relay routes opaque blobs and cannot read a single word.
No accounts
A human-readable group code is the only credential. No sign-up, no phone number, no directory of who talks to whom.
Invisible in screen sharing
Every surface showing a message is excluded from screen capture. Your Zoom or Teams audience sees nothing — only the physical display does.
Native to the notch
Built in SwiftUI. Messages glide out of the MacBook notch with haptic hover and one-click copy. Macs without a notch get a floating panel.
Scriptable
The munkel CLI sends whispers straight from your terminal — and an MCP server is on the way, so even your agent can munkel.
Rumor has it, it's almost ready.
Munkel is in active development and coming to macOS soon. Until then: lean over, cover your mouth, and whisper the old-fashioned way.
