Call anyone. Understand everyone.
Queso calls come with live subtitles — transcribed and translated into your language as the other person speaks, right on your device. Talk face-to-face across languages, then hang up to a full transcript of everything that was said. The only call where nothing gets lost in translation.
Read every word, as it's spoken
Start a video call and Queso puts live captions on screen — the other person's words, transcribed and translated into your language the moment they say them. Speech recognition and translation run entirely on your iPhone, so the call itself stays end-to-end encrypted and private.
- On-device transcription and translation — nothing is sent to a server to be understood.
- Subtitles toggle on or off with a single tap.
- 1:1 voice and video over WebRTC, end-to-end encrypted.
A two-way interpreter in your pocket
On a voice call, put the phone on speaker and Queso interprets both sides at once — each person hears and reads the other in their own language, with big, glanceable captions. Sitting across a table from someone who doesn't share your language? It works just as well for the conversation right in front of you.
- Interprets both directions on one call.
- Large captions sized for speaker mode.
- Set "the language I speak" so you're transcribed accurately.
The whole conversation, waiting for you
Hang up and nothing's lost. Queso keeps a full, speaker-labelled transcript of the call — free, with every line in your language — so you can go back and check exactly what was said. On Pro, an AI summary distils what was discussed and agreed into a few lines, ready to act on.
- Full transcript of every call, free.
- AI summary in your language on Pro.
- Copy it, keep it, follow up with confidence.
For every conversation that crosses a language
If the other person speaks a different language, Queso is the call that still just works.
International business
Close deals with suppliers and clients abroad without a translator on the line — and keep the transcript for your records.
Family across borders
Grandparents, in-laws, relatives who speak another language — call them and understand every word, both ways.
Customer support
Help customers in their language over a call, and let the summary write your follow-up for you.
Travel & relocation
Sort the apartment, the contract, the appointment — call ahead and interpret the conversation in real time.
Suppliers & trades
Confirm the order, the quantity, the delivery date out loud — and read it back, translated, before you hang up.
In-person, side by side
On speaker between two people, Queso interprets both sides — a pocket interpreter for the conversation in front of you.
Translated, not overheard
Queso 1:1 calls are end-to-end encrypted over the Queso Network, and the live subtitles are produced on your own device — your speech isn't shipped off to a server to be understood. The relay helps the two phones find each other and nothing more. See how it all works on the Security page.
Have the conversation anyway
Queso is coming soon to the App Store. The call that speaks everyone's language is nearly here.
