Watched It! is a free Chrome extension developed by webagent. It falls under the category of Browsers and is specifically categorized as an Add-ons & Tools. This extension allows users to keep track of the videos they have already watched on YouTube.

With Watched It!, users can easily mark videos as watched, helping them keep track of their viewing history. The extension is designed to work with YouTube and requires Chrome Version 20+ to function properly.

Although the extension provides a useful feature, there are a few known bugs. Currently, only videos that are displayed when the YouTube site is initially loaded will be removed from the watched list. If YouTube loads additional videos using methods like AJAX, these videos will be displayed without any changes. However, the latest version, V1.2, includes bug fixes for the popup and addresses some minor issues with sync storage.

In V1.1, the extension introduced the use of sync storage, which allows users to access their watched history across multiple systems. Additionally, users now have the option to deselect a video by pressing a button, effectively removing it from their history.

Please note that V1.0 is an alpha version, and while it may not be fully functional, the developer welcomes feature requests via email at

Overall, Watched It! is a helpful Chrome extension for keeping track of watched YouTube videos. However, the limited removal of watched videos and the need for further bug fixes may impact the user experience.
