Meet Lingo

Your new study partner adapts to whatever you watch.

Lingo sits in your browser, reads the captions as they happen, and keeps a running list of words you've seen — so you can tell what's new from what's clicking. No streaks to guilt-trip you. No deck to manage.

20 languagesPick any pair you watch — slang, idioms and context, all handled

LingoLens layers dual captions and a self-building word bank onto whatever you're watching — you don't change a thing about how you watch. Two platforms today, and more on the way.

01

Open any video in the language you're learning.

LingoLens activates the moment you open a video on a supported site. No URLs to paste, no buttons to press — just start watching.

Review later. Without the grind.

Unknown words turn into flashcards in context — with the clip of the video where you saw them. Spaced repetition, but memorable.

Why it sticks

Learning that hides
inside what you already do.

Every word, in context.

No more abstract lists. Your saved words replay the exact second of video where you first met them.

Any language you watch.

20 languages and counting. Gendered nouns, regional variants, and fast native speech — all handled.

Learns your level quickly.

After a handful of videos, LingoLens knows which words to highlight for you and which to leave alone.

Private by default.

Your vocabulary lives on your account — never sold, never shared. We track what helps you learn, and nothing more.
