## Description

<strong>The Fluent Immigrant turns YouTube, Netflix and Prime Video subtitles into interactive English lessons for Portuguese and Spanish speakers.</strong> 

Click any word in the subtitle to see its meaning, hear it, and save it to your vocabulary. Every saved word becomes a flashcard with spaced repetition, so what you learn while watching actually sticks. Dual subtitles (English plus your language) are one click away.

You already watch a lot of English. YouTube at lunch, Netflix at night. Almost none of it sticks, because you never do anything with the words. This extension is where you do something with them.
