What is MOS?
MOS adds high-quality subtitles to Netflix — in languages Netflix doesn't offer.
The problem MOS solves
You find an amazing foreign drama on Netflix. And then… no subtitles in your language. Dead end.
Netflix only provides subtitles for the languages they licensed. Most of the time, that's just 2 or 3 languages. Often not yours.
What MOS does
MOS generates subtitles in your language for any Netflix title — even the ones Netflix never translated. And we're not talking robotic word-for-word output. MOS understands the show: characters, era, tone, slang. The subtitles read like a real subtitler wrote them.
Why it's different
Netflix's own subtitles
Don't exist for most foreign titles.
Other translation tools
Stiff, literal, miss the jokes and context.
MOS
Reads like a professional subtitler did it.
What's a Chrome extension?
It's a tiny add-on for your Chrome browser. Install once, forget about it. When you open Netflix, MOS just works — subtitles appear right on the video, exactly like Netflix's own.

💻 Heads up — desktop only.
MOS runs on Chrome for Mac, Windows, or Linux. It doesn't work on phones or tablets, since Netflix's mobile apps don't support browser extensions. Grab your laptop.
When Netflix doesn't offer subtitles in your language, MOS fills the gap.
