YT Skin is a Chrome extension/add-on developed by 81bit. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. The program allows users to save videos and channels on YouTube without the need to log in to their Google account.

When watch history is turned off on YouTube, the recommendations on the home page are also turned off. However, with YT Skin, recommendations continue to work even if the user is not logged into their account. This extension provides the functionality to save videos and channels without the need for a Google account login.

To save a video, users will see two buttons in the navbar of every YouTube video. The Save button saves the video along with its title, while the Subscribe button saves the channel. Saved videos and channels can be accessed by clicking on the add-on button.

YT Skin is a free extension/add-on that offers a convenient way to save videos and channels on YouTube without the need to log in. If you're someone who enjoys exploring YouTube without an account or wants to easily save content, YT Skin is worth giving a try.
