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. The subtitles read like a real subtitler wrote them.

Why it's different

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.
