Reading Info is a free Chrome extension developed by cubeleco. This tool displays reading time, word, and character counts in a toolbar popup. It provides reading information for text on webpages, articles, and selected text, with a focus on article elements. The extension shows total character count, characters excluding white space, number of screen lengths, and a progress percentage of page scrolling.

Reading Info offers customization options such as adjusting words per minute reading speed and toggling between webpage and article info. Users can set a command keyboard shortcut for quick access to the popup, optimizing space on the browser toolbar.
