Autotube is a free Chrome add-on developed by Singularity Labs that allows you to continue playing YouTube videos even when you are browsing other tabs. This feature is incredibly useful when you want to multitask and watch a video while working or browsing the internet.

To enable this feature in Chrome, simply follow these steps:

1. Navigate to the YouTube video you want to watch while using other tabs.

2. Click the action button on the Chrome tab bar (make sure you have pinned it before).

3. The video will now play in a floating window that you can freely move around and resize as needed.

4. You can then browse other tabs in Chrome while the video continues to play in the PiP (Picture-in-Picture) window.

Please note that this feature may not be available on all streaming platforms or in all regions. However, for YouTube videos, Autotube provides a convenient way to enhance your multitasking capabilities and enjoy your favorite content.

It's important to mention that Autotube is an unofficial extension and is not affiliated with YouTube or Google. It is developed and maintained independently by Singularity Labs.

With Autotube, you can now enjoy the convenience of multitasking with ease, never missing a moment of your favorite YouTube videos.
