YouTube Premium users will now get to test new experimental features in a special program1
In the past, YouTube tested upcoming features, such as the iOS 14 Picture-in-Picture mode with random users, along with beta app testers. Google is now offering an interesting Labs program for its Premium subscribers, giving them access to experimental features if they wish to test them.
Some of the new features that are available only to Premium users include: watching and searching within videos directly from the home screen on iOS, or searching for videos using your voice. The latter is currently available only for the web version of YouTube. A third feature lets you filter by topic in Spanish, French, or Portuguese.
