LingoLens

LingoLens turns Spanish YouTube into an active learning workspace. As you watch videos, you can interact with subtitles, see instant English translations and definitions, and save unfamiliar words without leaving the video. The extension is built for Spanish learners who want to learn from real content instead of isolated drills. Saved words sync to your LingoLens account, where you can organize them in your Word Bank, review definitions and example context, and study with spaced repetition flashcards. Key features: • Interactive Spanish subtitles on YouTube • Instant word translations and plain-language definitions • Save vocabulary to a personal Word Bank • Track words and videos you have already seen • Review saved words later with flashcards and spaced repetition • Sync learning progress with the LingoLens web app LingoLens currently focuses on Spanish to English learners and is designed to make YouTube a practical daily learning tool.
