This Firefox add-on extracts numerical values periodically.
Not only can Chartlet capture values directly displayed on a page, such as temperature or stock quotes, but it also allows users to extract more complex information, such as the rank of an item in a list, or the number of occurrences of an expression in one or several pages.
Chartlet also provides users with complete control over what is retrieved by their browser and how often scanning occurs. Each extraction configuration is controlled by a chartlet, and users can install and run as many chartlets as they need.
In conclusion, Chartlet is a must-have tool for anyone who wants to stay on top of website changes over time. Its intuitive interface, robust features, and flexibility make it an ideal software for those who value data-driven decision making.
