Voicify — On-Device Transcription
Privacy-first real-time speech-to-text app — all processing happens on-device, no audio ever leaves the phone.
The Problem
Existing transcription apps store audio on remote servers — a privacy concern for classrooms, legal settings, and personal use. Users needed a reliable transcription tool that keeps all data local.
The Solution
A single-purpose app that transcribes audio using on-device speech recognition. Nothing is recorded or transmitted — everything is processed and stored on the device.
What I built
Minimised UI to one screen, one purpose. Integrated Google's on-device recognition engine with Flutter's speech synthesis library.
Business value
Delivered a trusted, privacy-first utility with strong organic discoverability in its niche.
Outcome
Strong user trust as a result of privacy-first positioning. Used in classrooms, legal note-taking, and accessibility settings where server-based apps are not acceptable.
