Word Catcher is a Chrome extension designed to facilitate language learning by allowing users to effortlessly save words from any website. The installation process is straightforward: simply install the extension, pin it to your extension list, and start browsing. Users can highlight words they wish to save, and a star icon will appear, enabling easy saving with just a click.

Once words are saved, users can access them through the extension icon. Features include the ability to copy saved words to the clipboard or download them as an Excel file. Additionally, users can toggle the extension on or off and customize settings to determine whether the star icon appears on words in their native language or only on foreign words. The extension prioritizes user privacy, storing all data locally in the browser without transmitting any information to external servers.
