Your tablet is already
a second monitor.

MultiScreen Link turns the devices you already own — an iPad, an Android tablet, an old laptop — into a real extended display for your computer. Not a mirror. A genuinely new desktop you can drag windows onto.

The difference

Mirroring shows you what you already have

Most apps duplicate your screen. That doesn't give you more room to work — it just puts the same pixels somewhere else.

Screen mirroring

One desktop, shown twice. Your windows stay where they were, your workspace stays exactly as small as it was, and the second device is a passive viewer.

A true extended display

MultiScreen Link registers a new virtual display with your operating system. Drag a browser, a terminal, or a full timeline onto it — the OS treats it like any monitor you'd plug in.

How it works

Connected in about ten seconds

No cables, no drivers to hunt down, no IP addresses to type.

01

Start a session

Open the desktop app and hit Start. It creates a session and shows you a six-character room code.

02

Enter it on your device

Type the code into the mobile app. The two devices find each other through our signaling server and negotiate a direct connection.

03

Drag a window over

The stream flows device-to-device over your Wi-Fi. Touch the screen and the input is relayed straight back to the host.

Built for real work

Everything a portable monitor does, minus the monitor

Direct peer-to-peer

Video travels straight between your two devices over WebRTC. No cloud hop in the middle, which is exactly why local streaming can stay free.

Touch that actually works

Taps, drags, and scrolls on the secondary device are sent back over a reverse channel and replayed as real input on the host. Included on the free tier.

Whatever you already own

Android tablets, iPads, iPhones, and old laptops all work as receivers. Hosts run on Windows and macOS.

Private by architecture

On your own network, your screen contents never leave it. The backend only relays the handshake that gets the two devices talking.

Off your network, too

Premium adds relayed streaming over the internet, so a laptop in a café can drive a display sitting at home.

Up to 4K at 60fps

Free sessions run at 1080p/30 — plenty for docs, chat, and reference. Premium unlocks the full 4K/60 pipeline.

Free where it counts

Streaming on your own Wi-Fi costs us nothing to run, so we don't charge for it.

Questions

Good to know

Is this just screen mirroring?
No. Mirroring copies your existing desktop. MultiScreen Link creates a separate virtual display that your operating system sees as a real monitor, so you get more workspace rather than a duplicate of the workspace you had.
Do I need to be on the same Wi-Fi?
For the free tier, yes — both devices connect directly to each other across your local network. Premium adds relayed streaming so the two devices can be on entirely different networks.
What do I need to run it?
A Windows or macOS computer for the desktop app, and an Android or iOS device for the receiver. Both apps are installed normally; there's no browser extension or system driver to configure by hand.
Can I touch the secondary screen?
Yes, and it's included on the free tier. Touch input on the receiving device is sent back to the host over a reverse data channel and applied as real input.
Does my screen go through your servers?
On a local connection, no. The server's job is to introduce the two devices and pass the connection handshake between them; after that the video flows directly. Premium's cross-network mode does route through a relay when a direct path isn't possible.
Why is the free tier actually free?
Bandwidth is what makes streaming expensive, and local peer-to-peer streaming uses none of ours. We only pay for infrastructure when you stream across networks, which is what Premium covers.

Give yourself another screen

Install the desktop app, install the mobile app, type a six-character code. That's the whole setup.
