Cross the edge
Push the cursor past the edge of your screen and it appears on the other computer, right where the two screens line up. Click, scroll and type there as if it were plugged in.
Coming soon for Windows and Linux
One mouse.
Two computers.
Slide your cursor off the edge of one screen and onto the next computer. Your keyboard and clipboard come along.
Feels like one computer.
Twinmouse joins your computers at the edges of their screens, so working across both is as natural as moving your hand.
Copy here, paste there
Text, images, even files and whole folders travel through the clipboard.
Arrange your screens
Drag the displays to match your desk. Multi‑monitor setups line up pixel for pixel.
See the other screen
Open the other computer’s screen in a window and control it from where you sit.
Private by design
Your computers talk directly, encrypted with AES‑256 and a key only they share. No account, no cloud.
Instant
Movement arrives in milliseconds. The mouse always goes first, even while big files are copying.
Set up in a minute.
Install on both
One small app for each computer. Nothing else to install.
Pair with a key
Enter the same key on both computers. They find each other on your network.
Arrange the screens
Put the other screen on the left, right, above or below. Done.
Pay once. Keep it.

Questions
Do my computers need the internet?
No. Twinmouse connects them directly over your local network. They just need to reach each other, on the same network or through a private network such as a VPN.
Is it secure?
Every message between your computers is encrypted with AES‑256 and signed, using a key that only your computers know. Nothing goes through a cloud service.
Which systems will it support?
Windows 10 and 11 first, then Linux, both X11 and Wayland (GNOME 45 or newer, KDE Plasma 6.1 or newer). You can mix them: Windows on one computer, Linux on the other.
What does it cost?
Try every feature free for 7 days. After that it’s a one‑time €20 for a lifetime license. No subscription.
When can I get it?
Twinmouse is being tested right now. Leave your email and you’ll get one message on launch day.
