VidStar is a Chrome extension that aims to help users find good videos on Youtube quickly. When faced with a multitude of colorful covers and tempting titles, it can be difficult to know which video to click on first. That's where VidStar comes in.

By installing the VidStar extension and reloading Youtube.com, users will see a star rating displayed below each video. The star rating indicates the video's popularity, with a maximum score of 3 stars and a minimum score of 0, similar to the Michelin Star system. This allows users to easily identify the most popular videos.

Not only does VidStar display star ratings on Youtube's homepage video list, search result video list, and recommended video list, but it also helps users identify ads hidden within these lists. This feature ensures that users can find the most popular videos quickly and avoid wasting time on irrelevant content.

VidStar's rating system is calculated based on several factors, including likes, views, and likes percentage. The percentage of likes to views is expressed as a star rating ranging from 0 to 3. Additionally, the number of views affects the weighting method of the star rating, with videos with fewer views tending to have fewer stars and videos with more views receiving more stars.

Overall, VidStar is a useful tool for Youtube users who want to quickly find popular videos without wasting time on irrelevant content. With its intuitive star rating system, users can easily identify the most popular videos and make informed choices about which videos to watch.
