Langscroll

Turn your Reels habit into a language class. Tap Transcribe on any video to get word-by-word subtitles, instant translations, and flashcards you can quiz later.

Learn a language from the videos you already watch.

Langscroll turns Instagram Reels, TikTok, and YouTube Shorts into a personal language lesson. Scroll content in the language you're learning, tap Transcribe, and instantly get word-by-word subtitles with translations — no flashcard grinding, no extra time on your phone.

HOW IT WORKS

1. Tell us the language you speak and the one you're learning.
2. Open Instagram (or TikTok / YouTube Shorts) inside Langscroll with your normal account.
3. Find a video in your target language and let it play.
4. Tap Transcribe — we generate aligned, word-by-word subtitles. Tap any word to see its meaning, pronunciation, and example sentences in your native language.
5. Bookmark words you want to remember. Quiz yourself later.

THREE WAYS TO WATCH • Default — subtitles under the video, so you can keep scrolling. • Review — step through the video sentence by sentence at your own pace. • Immersed — mute the original audio and let AI voices read the translation as you watch.

BUILD A REAL VOCABULARY Every word you bookmark goes into your Dictionary, organized per language and searchable. The Quiz turns those words into spaced flashcards, lets you focus on what you barely know, and tracks your progress over time.

WHY LANGSCROLL Most apps ask you to add a new habit. Langscroll uses the one you already have — the daily scroll — and quietly turns it into comprehensible input. Five minutes of Reels becomes five minutes of real exposure to native speech, slang, and culture.

CURRENTLY SUPPORTS English, French, and Spanish as both native and target languages. More languages coming soon.

PRIVACY You sign in to Instagram with your own account on their normal pages. We never see or store your social passwords. Video audio is sent to our transcription provider only when you tap Transcribe, and isn't retained. Your saved words and progress live in your account and aren't sold.
