Berlin

A window between languages

A wearable translator for the places where people work side by side without a shared language. It runs entirely on the device — no phone, no connection, nothing sent anywhere.

The idea

Language should never be the reason someone goes unheard

Every day, someone knows exactly what needs to be said and can't say it. A care worker who understands what a resident needs but not the shift instruction. A patient describing pain to someone who can't follow. Someone whose skill is invisible because the language isn't there yet.

ONU exists for that moment — one conversation, made possible.

From concept to circuit

One idea, at three stages of becoming real

A material concept, a hand-built form study, and the circuit boards that actually run inside it.

What makes it different

It runs on itself

Recognition, translation and speech all happen on our own board — no server, nothing to sign into.

Nothing leaves it

No recording is stored or sent anywhere, which turns a long data-protection review into a short one.

No phone required

Built for hands-on work and sterile areas, where personal phones aren't practical or allowed.

Shared, not personal

Belongs to the workplace, not one person — so the people who need it most don't have to buy it.

Where ONU is today

A working prototype, translating German and English fully offline.

Our own hardware, running the full pipeline on the device. We're now preparing for first testing with care and manufacturing teams in Berlin.

Sheikh S. Mahmud

Product designer and educator with a decade of experience across consumer and industrial products, and a lecturer in design and entrepreneurship in Berlin. ONU began with a simple observation: the places where being understood matters most are exactly where the tools don't reach.

A venture built at SkalaDesign.
