Watchd is a Chrome extension designed to help users monitor their video watch time on YouTube. This tool addresses the common challenge of losing track of viewing progress while binge-watching. By injecting a button into the current YouTube user interface, Watchd allows users to easily track their watch time on a per-video basis, displaying the information in a clear percentage format. This feature is particularly useful for those who want to manage their viewing habits effectively.

While Watchd provides a straightforward solution for tracking video watch time, it does have limitations. Notably, the data collected by the extension cannot be shared across different devices, which may be a drawback for users who switch between multiple platforms. Overall, Watchd serves as a practical add-on for anyone looking to maintain a better awareness of their YouTube viewing habits.
