Remote mode allows you to sync your scripts on multiple devices. For example, if you want to read from your iPad which is a fair distance away from you, you can use a nearby laptop to control the iPad. Just enable Remote mode for the script, then load the special URL on the iPad by scanning a QR code or manually typing it in, and then the iPad will sync with your laptop.
If you're using Voice mode to scroll, the laptop will be listening to you and scroll the page (and the iPad) automatically.
Remote Mode also makes it possible to use devices or browsers that don't have support for microphone. Just load the special URL and it will sync with a supported device!
