Turn any YouTube video into a language lesson.
LinguaTu is a Chrome extension for self-directed language learners. Watch real YouTube content in the language you're learning. Click words you don't know. Build a personal vocabulary deck that sticks.
Built first for Spanish, Portuguese, French, and Vietnamese speakers learning English. Other learning languages supported at launch.
What it does
Dual subtitles
See subtitles in the language you're learning and your native language side by side, directly in the YouTube player.
Click to translate
Tap any word or phrase in either subtitle line to see a translation, part of speech, and an example sentence — without leaving the video.
Personal vocabulary deck
Save the words you don't know. LinguaTu keeps the sentence, video, and timestamp so you remember the context later.
Daily review & Anki export
Review saved words on a simple spaced-repetition schedule. Export your deck to Anki any time — you own your data.
Built for self-taught learners.
Watching native content is one of the most effective ways to learn a language. The blocker is vocabulary: a fifteen-minute video can include ten words you don't know, and breaking flow to look each one up kills comprehension. LinguaTu makes that lookup take a single click and saves the word for later, so YouTube becomes a tool you can actually learn from.
