Nuenki is a browser extension that aids users in learning new languages by providing real-time translations while they browse the web. By assessing users' language levels, it selects appropriately challenging sentences for translation, facilitating personalized learning. Nuenki utilizes DeepL's translation technology, offering results that are more accurate than those from Google Translate. It also prioritizes user privacy, automatically detecting sensitive websites and sentences to ensure users' identities remain unlinked. Nuenki is compatible with all types of websites, allowing users to learn languages anytime.
