About this extension
Turn your phone into a remote for the videos and music playing in your browser tabs.
This extension works together with PhoneBoxSound, a free program for Windows that turns the phones you already own into synchronised wireless speakers, a media remote and an intercom for your PC (https://github.com/pritombarua1/PhoneBoxSound).
With the extension, every tab that plays video or music becomes its own player on your phone:
- play, pause, seek to the exact second, speed and volume, for each tab separately
- the tab's title and position shown live on the phone
- for ordinary web video, the picture can be kept in step with the phones used as speakers
How it works: the extension only talks to PhoneBoxSound on the same computer (127.0.0.1). It does nothing until you approve this browser once on the PhoneBoxSound dashboard. It sends nothing to any server on the internet: no account, no tracking, no analytics.
Needs: PhoneBoxSound running on the same Windows PC.
