Surf Learning - Open Beta is a Chrome extension developed by yavuzhancaskurlu. It falls under the category of Browsers and is a subcategory of Add-ons & Tools. This free application allows users to learn a new language while surfing the internet, particularly on YouTube.

The main feature of this extension is the instant translation of words in video subtitles. Regardless of your native language, you can choose the language you want to translate to from the extension configurations.
