How to remotely control this computer

Once remote control is on, you can view this computer’s screen and operate it with touch, mouse, or keyboard from the browser on a phone, tablet, or another computer. The controlling device needs no software.

Before you start

  • The computer you want to control is signed in to LaiCai Screen Mirroring and has active Premium
  • The browser on your phone, tablet, or other computer is signed in to the same LaiCai account
  • The computer stays on and online, with LaiCai Screen Mirroring running

Turn it on and connect

01

Turn on remote control on the computer

Open LaiCai Screen Mirroring, choose Tools → Control Helpers → Remote Control This Computer, and switch on “Allow remote control from other devices”. You need to be signed in; if this computer does not have Premium, the purchase window opens.

02

Grant the system permissions

On macOS, the status changes to “Other devices can connect” only after both Screen Recording and Accessibility show “Granted”. For anything missing, click Grant, turn it on in System Settings, then switch back to LaiCai Screen Mirroring.

03

Open your account on the other device

Sign in to the same account at laicaiapp.com in a browser, open “Control my computer”, pick a computer marked “Ready to control”, and select Control. If it says it is not enabled, recheck the first two steps on the computer.

Open “Control my computer”
04

Start controlling

Once connected, the computer screen appears on the page. On a phone, hold it upright; the table below explains each area.

Controls on your phone

From top to bottom, the page shows the computer screen, the touchpad, the left and right buttons, and a bottom toolbar.

Computer screen
Tap with one finger to click there; press and hold, then drag to drag; pinch with two fingers to zoom, and slide two fingers to pan the view.
Touchpad
Slide one finger to move the cursor, tap for a left click, slide two fingers to scroll, and tap with two fingers for a right click.
Left / right buttons
Hold to press and release to lift; hold the left button while sliding on the touchpad to drag.
Keyboard
Opens your phone keyboard to type on the computer. What your input method produces is typed as is, including other languages.
Shortcuts
Copy, paste, cut, select all, undo, redo, save, find, switch app, and close window, plus keys such as Esc, Tab, arrows, and F1–F12. Key combinations adapt to the computer’s system.

Safety and disconnecting

  • Only devices signed in to the same LaiCai account can control your computer.
  • While someone is controlling, a banner appears at the top of the computer screen; click it to disconnect.
  • Select Disconnect on the web page to end control. Switching off “Allow remote control from other devices” on the computer stops all devices from connecting.
  • The lock screen and system security prompts cannot be controlled; on Windows, windows running as administrator cannot be controlled either.
