Which streaming services does it work with?
Netflix, today. Prime Video, Disney+, Max and YouTube are planned, and we will say so here when each one works.
Which browsers are supported?
DuoSubs is a Chrome extension for desktop. Other browsers are not supported yet.
Which languages can I learn?
Any language a show has subtitles in. You choose the language you are learning and your own language, and the two lines follow those choices.
Do I need my own Netflix account?
Yes. DuoSubs adds subtitles and translation on top of the Netflix you already pay for. It does not give access to any content.
What happens when I reach 100 saved words on the free plan?
Your cards stay and you can keep reviewing all of them. To save new words, upgrade to Pro or delete cards you have learned.
What does Pro add?
AI subtitle translation that takes the scene into account, so idioms and jokes make sense. AI example sentences and hints on your cards. And no limit on saved words.
Is there a mobile app?
Not yet. Passive Polyglot is a web app, so your flashcards open in your phone's browser. A mobile app is planned.
Can I cancel Pro?
Yes, any time from your account page. Pro stays active until the end of the period you paid for, and your cards stay with you.
What does the extension read?
The subtitles of what you play and the text you choose to translate. Words you save go to your account so they can become flashcards. See the privacy policy for details.
