What PC Remote can do

Screen and picture

• Any monitor, or all of them stitched into one picture, laid out as in the Windows display settings.
• Zoom to the window, 100 %, 150 %, 200 % or 300 %, or with Ctrl and the mouse wheel.
• The screen is captured through the graphics card, which waits for something to change: a still screen is not read over and over. If that path is unavailable, it falls back to GDI and returns by itself.
• In JPEG, only the changed parts of the picture travel: moving the mouse costs two small rectangles, not a whole frame.
• The codec switches by itself, mid-session: JPEG for a calm screen, H.264 for motion. H.264 comes from Windows itself, on the graphics card (NVENC, Quick Sync) when there is one, otherwise on the processor.
• The stream adapts to the link: first the quality gives way, then the frame rate. The link's width is measured, and the video bitrate is cut to it. In a local network the presets neither shrink the picture nor lower the quality asked for; it gives way only while the viewer falls behind, and comes back.
• Four quality presets, each with a ceiling on how much of one processor core the other computer may spend on the picture. The numbers.
• Correct screen geometry with Windows scaling above 100 %.
• The watched screen does not go dark or start a screen saver. Content protected from recording arrives black, and the program says so instead of leaving you guessing.

Mouse and keyboard

• Left, right, middle and double clicks, selecting, dragging and the wheel.
• Keys and shortcuts, and text in any alphabet, whatever the keyboard layout on the other side.
• One button captures Alt+Tab, Win and PrintScreen, so they act on the remote computer instead of yours.
• The remote pointer is drawn as your own cursor and does not lag behind.
• Nothing stays pressed when the window loses focus or the link drops.
• Blackout: the remote screen goes dark and its own mouse and keyboard are locked while you work (Windows 10 version 2004 or newer on that computer).
• A clear warning when the other computer does not take input, for example because an administrator window is in front and the program runs without the service.

Shared clipboard

• Copied text travels by itself, both ways. Nothing to press.
• A picture on the other computer's clipboard arrives when you paste it, not before, in the format the receiving program asks for. A button sends your own picture there.
• Files and folders: copy them on one computer, press Ctrl+V on the other (Cmd+V on a Mac), between Windows and a Mac too. They cross the network only when pasted, and a paste is always a copy, never a move.
• Nothing is synced when you connect: only what you copy afterwards travels.
• Limits: text up to 1 MB, a picture up to 24 MB, files up to 1 GB per copy.
• What the other side offers is kept out of the Windows clipboard history and the cloud clipboard.

Files

• A two-pane window: your computer on the left, the other one on the right, with all its drives.
• Several files and folders at once; whole folders with their tree, empty folders included, in either direction.
• Drag files from Explorer straight into the window, or double-click a file to send it across.
• A summary before the transfer starts and one progress line for the whole queue. It stops at the first error and names the file.
• A half-copied file is never left behind pretending to be whole. Large files do not time out, and a transfer does not get in the way of control.

Sound

• What plays on that computer is heard on this one. One button turns it on, and the choice is remembered for each computer.
• Uncompressed in a local network, compressed over the internet, chosen by itself. When the link cannot carry it, the sound shrinks on its own and comes back later. What it costs.
• Switching headphones or speakers over there is picked up without reconnecting, and silence is never mistaken for a broken link.

Connecting

• The main window lists your computers in two rows, favourites and recent, each marked "nearby", "online", "offline" or "checking".
• Computers on the same network are found by themselves, when the window opens and every half a minute after.
• From anywhere, by the computer's nine-digit number: it is shown at the bottom of that computer's window, with a Copy button.
• Three routes, picked by themselves: the local network, the last known address, the relay. The local one wins.
• Control and picture come back by themselves after a drop. Quality, zoom and sound are remembered for each computer.
• Wake-on-LAN: a sleeping computer on the same network wakes from the right-click menu, if its network card allows it; the program learns its address while the computer is online.

Security

• Every connection is encrypted end to end, always, with nothing to configure.
• A computer is known by the fingerprint of its key, not by a name or an address, so not even the relay can pose as it.
• The password is never sent and never stored in the clear. It cannot be shorter than 12 characters, and over the internet it is required.
• The settings, with the computer's key, live in a folder other accounts on that computer cannot open.
• No telemetry and no update checks. Besides the computers on your network and the ones you connect to, the program talks only to the relay. What the relay sees.

Service mode

Installed as a service, the program starts with the computer and works before anyone signs in. That is what lifts the limits Windows puts on an ordinary program:

• the lock screen and the sign-in screen are visible and can be used;
• windows that ask for administrator rights take your mouse and keyboard;
• the program follows the desktop as it changes, to the lock screen and back.

Installs, updates and removes itself

• One file is both the program and its installer. One window asks for a folder and a way to run: as a service, at sign-in, or by hand.
• It adds its firewall rules itself and appears in the Windows list of installed apps.
• To update, run a newer file: it stops the installed program, replaces it and starts it the way it ran before. If the new one does not start, the old one is put back.
• Uninstalling removes everything it left behind, firewall rules included, and keeps only the computer's key, number, settings and list of known computers, so it comes back under the same number. A switch erases those too.
• Switches for scripts: install, update and uninstall without a single window. The list.
• English and Russian interface: it follows Windows (any other language gets English), or the choice in the settings.

Remote access to a Mac

The Mac version is the same program, for macOS 13 or later on Apple Silicon and Intel (tested so far on Apple Silicon only). A Windows PC controls a Mac and a Mac controls a Windows PC, with the same encryption, the same relay and a nine-digit number of its own. What is different:

• It works while you are logged in on the Mac: the service starts when you log in to your account. After a restart, nothing until you log in at the Mac itself.
• A locked Mac shows its real lock screen, and with the Accessibility permission the account password typed remotely unlocks it. So on a Mac the connection password is the only lock, and the setup assistant asks for it first.
• The program needs macOS permissions: screen recording, Accessibility and, on macOS 15 and later, Local Network. It has no Apple certificate, so after every update at least the first two have to be granted again.
• No blackout of the Mac's screen, and the people at the Mac see macOS's mark in the menu bar while the screen is shared.
• One of the Mac's monitors at a time: the stitched picture is made by the Windows version only. H.264 comes from macOS itself (VideoToolbox).
• The interface follows macOS when it is in English or Russian, or the choice in the settings; the installer's windows are in Russian for now.

Installing on a Mac, step by step.

Coming soon

One more program is in the works and not published yet.

• Android. The other computer's screen under your finger: a touchpad mode, where the finger moves the cursor, and a tap mode, where a tap puts it on the spot; pinch zoom up to 8×; scrolling with two fingers and a right click with a two-finger tap; a keyboard with Esc, Tab, Ctrl, Alt, Win, arrows and F1–F12.

What it does not do

• It does not record sessions: the picture is never saved anywhere.
• It does not work over IPv6: on a network with IPv6 only, it will not answer.
• There are no user accounts: a computer has one password.
