WebsiteVisitHours is a Chrome extension developed by nurgasemetey. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory. This free extension allows users to mark websites where they tend to procrastinate the most.

The main feature of WebsiteVisitHours is the ability to set a time interval during which you are allowed to visit certain websites. For example, you can specify a time interval of every hour between 45 and 59 minutes.

Websites that fall outside of the specified time interval will be marked with a red border, serving as a visual reminder to stay focused. However, if you visit a website within the defined time interval, it will not be marked.
