Origin Story

Born From a Viral Moment.

Auvi started as a homemade Raspberry Pi transcriber — and went viral. People from every walk of life asked: "Can you make this into an app?"

The Raspberry Pi Transcriber

A homemade device for a family member who needed captions — live speech-to-text on a small screen, running entirely offline.

Reddit Goes Wild

Posted to r/raspberry_pi, the project gathered thousands of upvotes and hundreds of comments. People wanted it for accessibility, travel, meetings, lectures — everyone asked: “Can you make this into an app?”

Auvi Is Born

Same mission, now in your pocket. Captions, translation, speaker identification — fully on-device, no subscription nonsense. Built in Hong Kong by a British developer who sits on the doorstep of the world’s electronics capital.

★★★★★

“Finally, a transcription app that doesn't send my conversations to the cloud. The speaker colours are a game-changer for group settings.”

★★★★★

“I've tried Ava and Otter. Neither work offline. Neither give me real speaker identification. Auvi does both — and it's a one-time purchase.”

— Coming soon from TestFlight testers
★★★★★

“The scam detection feature warned me about a suspicious caller before I even realised what was happening. Worth it for that alone.”
