YouTube Rating Extension is a Chrome add-on that enables users to assign numerical ratings from 1 to 10 to YouTube videos. With this extension, users can go beyond the traditional "Like" button and provide a more detailed evaluation of the content they watch. It offers a user-friendly interface for submitting ratings and accessing the database of all submitted ratings.

This extension by Lily Yang enhances the YouTube viewing experience by allowing users to participate in a rating system that offers more nuanced feedback than a simple thumbs-up. It falls under the Browsers category and specifically the Add-ons & Tools subcategory, providing an additional layer of interaction for YouTube enthusiasts.
