Present in your language, the room hears theirs
A pitch at a trade fair, a class with international students, a guided tour, a team briefing. You speak your language. Each person in the room scans your QR code, picks their language, and listens to you live on their own phone.
Why the usual options fall short
Simultaneous interpreting means booths, headsets and interpreters booked weeks ahead. Without them, you speak a language half the room only half follows, or you translate your slides afterwards, when the questions are already gone.
How it works
-
Choose “I’m presenting”
Open a presentation in the app. A QR code appears, ready to show on a screen or to share.
-
The room scans
Each listener picks their language and follows in their browser, with subtitles. No app, no account. Before you start, you see how many people wait in each language.
-
Keep a record
For a meeting, record it with Voice notes, up to two hours: Duo writes the transcript and a summary, translates them in one tap and exports to PDF, Word, Markdown or text.
For example
A founder pitches in Spanish at a trade fair in Dubai. Visitors scan the code on her stand screen: one listens in Arabic, another in English, a third in Chinese. That evening, her team records its debrief as a voice note and sends the summary to the investors in English.
Questions
Do listeners need the app?
No. They scan the QR code and listen in their browser, without an account.
Can listeners talk back?
No. A presentation has one speaker and a listening room. For a conversation in both directions, use the remote call or the one-phone mode.
How many people can listen?
Up to 100 listeners per presentation, each in the language they choose.
