One phone
Put it on the table between you. The screen splits in two, one side for each person. If the other person switches to a third language, Duo follows.
Scan. Speak your language. They hear theirs.
Déblo Duo is a real-time AI interpreter for voice conversations. You talk naturally, in your own words, and the other person hears you in their language as you go. They answer in theirs, and you hear it in yours.
Scan and Talk
Your own QR code is on the home screen. The person in front of you scans it with their phone camera, picks their language, and you accept the request like an incoming call.
- You approve every request: nobody joins without your yes.
- The code on your screen renews itself every 20 minutes.
- You pay, and only after you accept. Scanning is free for the other person.
A sticker for your counter
Print a fixed QR code and put it where people can see it: a shop, a market stall, a travel agency, a hotel front desk. Customers scan it and talk to you in their language. "Change my code" makes the old sticker stop working at once.
Other ways to talk
Two phones
Face to face, each of you speaks into your own phone.
Remote
Send a link by WhatsApp or email. Your guest opens it, picks a language and talks from their own phone, with no app and no account.
I’m presenting
Present, pitch or teach in your language. Up to 100 listeners scan your QR code and hear you live in their language, with subtitles.
By situation
After the call
Every conversation gets a detailed summary in your language and the full transcript. Search them by any word and share them in one tap.
Voice notes
Record a lecture, a meeting or your own ideas, up to 2 hours per note. Duo writes the transcript and a summary, translates both in one tap, and exports to PDF, Word, Markdown or text.
Languages
English, French, Spanish, Portuguese (Portugal and Brazil), Arabic, Chinese (Simplified), German, Korean, Japanese, Turkish and Hindi. The app itself is available in 19 languages.
Pay only when you talk
No subscription. Billing starts only when both of you are in the conversation: waiting for your guest is free. Try a conversation on one phone before you even create an account.
Same account as Déblo
Sign in with your WhatsApp number or your email. Déblo Duo shares the account and the balance of the Déblo app.
Déblo Duo is an AI interpreter and does not replace a certified interpreter. For medical decisions, legal acts or any situation where a single word matters, rely on a certified human interpreter.
