ScreenPortal

The idea

Share one portal. Nothing else.

A portal is exactly one thing — a region of your screen, a whole window, or a region inside a window. Everything else on your Mac stays where it is: unseen, untouched.

A window

Pick any open window and send just that. It keeps updating live, at full size, in your hand.

A region

Drag a box around any patch of screen. Only what’s inside the box ever leaves your Mac.

Part of a window

Just the toolbar. Just one panel. Frame the slice you care about and leave the rest behind.

Touch control

Reach in and adjust.

Send one panel — here, Photoshop’s Layers — to your phone and toggle, reorder or retouch with your thumb, while the canvas fills the big screen on your Mac.

Multi-portal

Carry a whole workspace.

Pin several portals to one phone and flick between them like apps — the canvas here, a panel there — or hand each phone its own portal, all streaming from one Mac at once. Idle portals cost nothing.

Zoom only · nothing sent

Look, don’t touch

Or just watch — privately.

Flip on zoom-only and your phone becomes a loupe. Pinch into a detail, pan around — and not a single tap reaches your Mac. Perfect for checking a proof or reading a value from across the room.

Virtual display A panel parked off your real screen

Virtual display

Room your screen doesn’t have.

ScreenPortal can spin up an invisible extra display — one that never shows on your monitor — and capture straight from it. Park the panels or windows that don’t fit (extra tools, a reference, a second timeline) on it and stream them to your phone. Your Mac’s screen loses nothing; the overflow just lives in your hand.

Yours only

On your network. Behind a PIN.

Pairing takes a rotating PIN and your approval, right on the Mac. Only the portal you pick is ever shared — and everything stays on your local Wi-Fi.

Get going

Three steps to your first portal.

Install the host

Download ScreenPortal for Mac, open it, and grant Screen Recording and Accessibility when asked. The host shows an address, a QR code and a PIN.

Pair your phone

Open the app, scan the QR, type the PIN, and approve it on the computer.

Pick a window

Choose a window, a region, or part of one — and it’s live in your hand.
