Sublingo Language Learnin

Learn languages naturally while watching YouTube and Netflix. SubLingo overlays translated subtitles in real-time, lets you hover any word for instant definitions, and helps you build lasting vocabulary — all without leaving your video.

How it works:
1. Install & Play — Open any video on YouTube or Netflix. SubLingo automatically detects subtitles.
2. Hover & Save — Hover any word for instant translation, pronunciation, and definitions. Save words with one click.
3. Review & Master — Practice with smart flashcards powered by spaced repetition. Five exercise types keep reviews fresh and effective.

━━━━━━━━━━━━━━━━━━━━━━

DUAL SUBTITLES
See both the original and translated subtitles at the same time, perfectly synced with the video. Switch between four display modes: Dual, Original Only, Translated Only, or Off — right from the in-player menu.

HOVER TRANSLATE
Hover any word in the subtitles to see its translation, pronunciation, part of speech, and full dictionary definitions. No copying, no switching tabs — just hover and learn.

SELECT-TO-TRANSLATE ON ANY WEBSITE
Not just for videos. Select any text on any webpage to get an instant translation popup with dictionary details. Great for reading articles, social media, or forums in your target language.

VOCABULARY BUILDER
Save words with one click. Each word is stored with its translation,
pronunciation, the original sentence, and the video it came from — giving you
real context when you review.

SMART FLASHCARD REVIEW
Review your vocabulary with the proven SM-2 spaced repetition algorithm. Five exercise types keep things engaging:
• Translation Quiz — See a translation, type the word
• Fill in the Blank — Complete the sentence
• Listening — Hear the word, type what you hear
• Image Recognition — See an image, recall the word
• Context Recall — See the original sentence, fill in the missing word

Track your streak, accuracy, and progress over time.

IN-PLAYER CONTROLS
A control button sits right inside the video player. Open the dropdown menu to switch subtitle modes, adjust font size, change colors, tweak background opacity, and more — without leaving fullscreen.
