Feature 01
Dual Subtitles
Every line appears twice — the original on top, your language right underneath. You follow the scene naturally and your brain starts connecting the two without effort.

Sublingo
Fluent, one subtitle at a time. Sublingo turns the shows and videos you already watch into real language progress.
Features
Hover over a feature to see it in action.
Feature 02
Contextual Translation
Tap any word in the subtitle and Sublingo gives you its meaning in that exact sentence — plus pronunciation and how it's used — without pausing the scene or leaving the video.
Feature 03
Saving Vocabulary
One tap on Save and the word is yours. It lands in your Saved list with its meaning and the video you met it in, so nothing you learn just slips past you.
Feature 04
Subtitle Side Panel
The whole transcript sits beside the video with timestamps and tags — Easy, Medium or Hard, and whether a line is grammar, vocabulary, an idiom or a cultural note. Click any line to jump straight to that moment.
Feature 05
Smart Subs, Tuned To You
Tell Sublingo what you speak, what you're learning and your level — then it adapts: too-easy lines get hidden, translations are handled by AI, and you can toggle Sublingo on or off right in the player.
