Vocab Master is a free Chrome add-on developed by expercise Labs. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This program aims to enhance your English vocabulary while you surf the web.

With Vocab Master, you can activate the reminder feature and set the reminder period according to your preferences. Once the period ends, Vocab Master will intercept your web page request and display a random vocabulary word from the vocabulary list that you have selected on the options page. Each vocabulary item in the list comes with a simple definition in English and example usages, allowing you to understand and apply the word in context.
