Copy here. Paste there. Any device. One keystroke.
A clipboard that follows you between Mac, Windows and iPhone. One keystroke, encrypted end to end, and nothing running while you are not using it.

One keystroke is the whole interface.
Option + Space on a Mac, Ctrl + Shift + S on Windows, Meta + Shift + V on Linux, opens a 500 pixel window over whatever you were doing. Type or paste, press Enter, it is gone again. There is no main window to go back to, because there isn’t one.
Sealed before it leaves the room.
Set a passphrase and the key is derived on your device and never leaves it. There is no cloud backup of it, no recovery link, nothing we could be compelled to produce.
A second device gets the key by scanning a QR code off the first one. That is the only way, on purpose.
The row as stored
Asleep until you need it.
While the window is hidden every animation and stream is paused — not throttled, paused. The only thing still listening is the hotkey. Idle cost is 0.0 % CPU, which is the entire reason it can sit in your tray forever.
And it is in your pocket.
Tap the notification and the text is on the phone’s clipboard. Ignore it and the clip is waiting in the app’s history anyway.
Going the other way is paste‑then‑send, because both mobile systems block background clipboard reads — and they should.
It reads what you copied
JSON gets a prettify button. A JWT gets decoded to its payload and expiry. A hex colour gets a swatch. Offered, never applied behind your back — everything else passes through byte for byte.
It knows when to shut up
Game mode spots a full‑screen app and holds every notification until you are back on the desktop. No toast over your raid, no popup in the middle of a presentation.
It is scoped at the database
Row‑level security means your rows are unreachable from another account even if the application layer got something wrong. The database enforces it, not the app.
