A note about security warnings

Early-access builds may not be signed yet. On Windows, a "Windows protected your PC" dialog can appear: click More info and then Run anyway. On macOS, if Summondesk "cannot be opened", right-click the app in Applications, choose Open and confirm.

Setting it up

Open your dashboard and click Add computer. You get a six-letter pairing code.
Windows: run the installer, then open Summondesk from the Start menu. macOS: drag Summondesk into Applications and open it. Enter the code in the app to link this computer. Updates keep your existing pairing.
On macOS, allow Screen Recording and Accessibility when asked (System Settings > Privacy & Security). On Windows, choose Allow Windows connections in the app and approve the Windows prompt to allow Summondesk through the firewall.
The computer shows as online in your dashboard. Click it to connect. Enable the app's start-at-login option if you want it to start automatically.

On the device you connect from

Open your dashboard in the browser. There is no second app to install. Use the small menu button in the stream for full screen, resolution and desktop size. On a phone, swipe as a trackpad and pinch to zoom.

Copy text or a screenshot, focus the remote chat or editor, then paste with Ctrl / ⌘ + V. Clipboard & files in the session menu also lets you send files. Updates replace the host app and keep its pairing.
