Infocus is a Chrome extension developed by Anton Cao that helps users stay focused while browsing the internet. This simple and free extension allows users to input distracting websites, such as YouTube or Facebook, and Infocus will automatically prevent them from visiting these sites.

When a user tries to access a blocked website, Infocus will either take them back to the previous page or close the tab entirely if it is a newly opened tab. This feature helps users avoid distractions and stay on track with their work or tasks.

One unique aspect of Infocus is that if a user needs to temporarily disable the extension for a specific reason, they must solve a mental math problem. This adds an extra layer of mindfulness and encourages users to think twice before disabling the extension.

Infocus is also open source, with its code available on GitHub for users to review and contribute to. Users can provide feedback or request new features by opening an issue in the GitHub repository.
