# LingoBinge

> A free Chrome extension that swaps YouTube and Netflix subtitle words into Indonesian so you learn while you watch.

LingoBinge lets you tap any word to translate it, hear it, and save it for spaced-repetition review. No streaks, no guilt.

## What the extension actually supports

The browser extension grades subtitles for these languages today: Indonesian. That is the complete list.
We also publish free learning content (guides, show picks, vocabulary) for Spanish, French, Japanese, Korean, German, Italian, Portuguese, Turkish, Hindi, Mandarin Chinese, Russian, Polish, Thai, Swedish, Dutch, Arabic. That content is reference material only. The extension does not grade those languages yet, and those pages offer a waitlist rather than an install.
