This extension is a tool that can be used to detect cats in web pages that you are browsing. It uses Google Cloud Vision to identify the cat in the page that you are browsing. By using it, you can count the number of words containing cat expressions in the current page, and you can play a beep sound on detection. The app also supports some commands to control the behavior of the tool.

It is important to note that the tool is not a perfect detector, and that it is not perfect in every case.
