Beforeleave is a free Chrome extension developed by Yongjun Park aimed at combating the issue of information overload and forgetfulness in the digital age. In a society where concentration often deteriorates due to the sheer volume of content encountered, Beforeleave offers a solution. This extension prompts users with a dialog box to leave comments on the content they are about to leave behind, aiding in better retention of valuable information.

The key feature of Beforeleave is its ability to display a dialog box when users attempt to exit a page, allowing them to jot down thoughts or notes before moving on. This feature is customizable, ensuring that the dialog box only appears on selected pages and after a specific duration of time, enhancing user control and convenience.
