Lenny Tab is a Chrome extension that allows you to passively learn new languages every time you open a new tab in your browser. With this extension, there is no need for cramming or boring classes. Simply install the extension and continue with your daily activities.

The main features of Lenny Tab include a new word with translation every time you open a new tab, audio pronunciation for every word, examples of using the word with audio, and more than 30 sets of words for any level of language knowledge. Additionally, there are exercises available for memorizing words and the option to search using popular search engines like Google, Bing, DuckDuckGo, and Yandex.

Privacy is a priority for Lenny Tab, as the extension does not track your searches or any personal information. The focus is solely on helping you learn new words without any distractions. It's important to note that after 7 days of usage, a small ad block is displayed on the new tab screen to further support the mission of teaching users new words.

Overall, Lenny Tab offers a convenient and passive way to expand your language skills while going about your daily browsing activities.
