Welcome to Sublens
You are ready to turn subtitles into a language lesson. Here is how it works.
The basics
Reveal a blurred subtitle
Subtitles are blurred by default so you can test your listening first. Hover over a line to reveal it. Pausing the video reveals all of them at once.
Translate a word or phrase
Click a word for its translation and dictionary entry. Ctrl/Cmd+click to add more words to the selection, or click and drag to select a whole phrase.
Hear the pronunciation
The selected word or phrase is pronounced automatically in the subtitle language when the popup opens. Use the speaker button to replay it.
Replay the previous line
Press ← (Left Arrow) to jump back to the previous subtitle and hear it again. When there is no earlier subtitle, the key performs the player's normal rewind.
Make it yours
Open the settings
Click the Sublens icon in the Chrome toolbar to choose your subtitle (source) and translation languages, toggle the behaviors above, and enable or disable Sublens on Netflix and YouTube independently.
On YouTube
Turn captions on with the player's CC button. Both manual and
auto-generated captions are supported on
youtube.com/watch pages.
