One file, then the chord.
One small script you leave running — no installer, no account. It does the three things a browser tab is not allowed to: answer a global hotkey, focus the window you came from, and press the keys.
Reachable only by you
Binds to 127.0.0.1. Talks only to promtly.dev — for the board and an update check — and sends nothing of yours.
Verifies before it types
If Windows refuses the window switch, it says “press Ctrl+V” instead of typing into the wrong place.
Open, because you run it
One MIT-licensed file, no dependencies. Read every line before you trust it.
Windows, for now
The board works everywhere. The keystrokes are Windows-only until macOS and Linux land.
- 01
Download it
Save it to Documents, not Downloads — it fetches the bridge into that folder. Your browser calls any .cmd unsafe: open the downloads list and choose ⋯ → Keep → Keep anyway.
- 02
Double-click it
The black window that opens is the bridge — leave it running. A blue “Windows protected your PC” box is SmartScreen meeting a new file, not a virus warning: More info → Run anyway. The launcher opens by itself.
- 03
Press the chord, in any app
It pins the window you are in, opens the launcher over it, and firing a pad types there.
Ctrl+Shift+SpacesummonCtrl+Alt+Ccapture selectionUsually these — if another app owns one, it picks a free chord and the window prints which.
Needs Node.js LTS. Not allowed to install it? The board still works in the browser — pads copy instead of typing.
