Tap keys on your phone and they type on your Mac or Windows PC over your local Wi‑Fi — no extra hardware, no cables. Design the keyboard you actually want: add keys, build shortcuts (including combos like Cmd/Ctrl, and left/right modifiers), arrange them on a grid, and switch between layers and modes. Keep your most-used shortcuts one tap away. HOW IT WORKS Sidekey works together with a small, free desktop helper you run on the computer you want to control. Put both devices on the same Wi‑Fi, scan a QR code once to pair, and you're connected. Pairing is secured with a token, and your keystrokes travel directly to your own computer — never through us.
