Why Vox exists

Dictation should feel instant, private, and owned.

Most voice tools rent you access to a cloud workflow. Vox is a small local system you can inspect, modify, and keep.

Local by default

Audio is recorded and transcribed on the Mac using whisper.cpp. The default fast path does not send your voice to a cloud transcription service.

Fast enough to use all day

The Whisper server stays warm, the language is pinned, and deterministic corrections handle brand names without an extra LLM pass.

Operator vocabulary

Add client names, tools, jargon, and repeated corrections directly in the config. Vox gets better where your work is specific.

One-key workflow

Pick Right Option, Right Command, Left Option, or Left Command from the menu. Double-tap for hands-free lock. Release to paste anywhere.

Optional cleanup and translation

Ollama cleanup and translation can be toggled on when you want polished or translated output. Keep them off when raw speed matters most.

Open-source package

The download includes the Lua app, installer, sounds, README, and MIT license. Large models are downloaded during setup to keep the package light.

Who this is for

Founders, operators, writers, builders, legal/documentation-heavy users, and anyone who wants faster text input without uploading every spoken draft to a third-party transcription platform.

What it is not

It is not a polished SaaS product, mobile app, Windows app, or hosted transcription service. It is a practical local Mac system built to be hackable and fast.

Open-source lead magnet

Ship faster by speaking.

Vox is one small example of the AutomateScale operating style: build the tool, package it cleanly, and turn useful internal infrastructure into a public asset.
