What is Duolingo Ninja?

Duolingo Ninja preview

Duolingo Ninja is a Chrome browser extension designed to reinforce language learning by integrating Duolingo vocabulary practice into everyday web browsing. It syncs directly with the user's Duolingo account to identify known vocabulary and translates words or sentences on visited web pages accordingly. This approach allows learners to apply their language skills in real-world contexts without altering their browsing habits, making vocabulary acquisition more practical and engaging. The extension offers flexible translation modes, privacy-conscious operation, and tools to review and practice learned vocabulary with flashcards and AI-generated sentences.
