PUENTE

Speak. Listen. Understand.

Puente translates what you say in the moment, in your pocket, without sending your voice to any server. For when language is the only border left.

How it works

Three steps. No accounts. No mystery.

Get the app

Coming soon to Google Play. Until then, the code is open on GitHub — you can read it, audit it, and contribute.
Download the engines once

The first time, you choose on the phone what you need to listen and translate. After that, you don’t need the internet.
Speak live

You turn on the mic and the translation appears instantly. You control the device. No one else is listening.

03 / 05 · LOCAL

Your conversation stays on your phone

After the first download, Puente works without a network — even in airplane mode. Audio is processed on the device and is not saved. Real privacy, not fine print.

04 / 05

You choose for your phone

No unnecessary jargon: different sizes so it runs well on more devices.

01 · WHISPER

Listening

Whisper Tiny, Base, or Small: faster, balanced, or more precise. You decide based on your device memory.

02 · NLLB

Translation

NLLB is the translation engine: hundreds of language pairs, built to run on a phone.

iThe download takes space; pick what fits your phone best.

From the community, for the community

Puente was born while travelling, when language was the only border left. It is free software under the MIT license: free, auditable, and modifiable. Made by Pablo Vallejo — one person, not a company waiting for the next funding cycle.

Not waiting on the fiscal year

While Brussels waits for grants to mature, useful work can already fit on a phone. Puente exists for people who need to understand each other today — not next fiscal year.
