Mundwerk is a fast, private dictation app for macOS that turns your voice into text right where your cursor is — fully offline, no cloud, no subscription.

Built for Apple Silicon Macs, Mundwerk uses on-device speech recognition (OpenAI Whisper accelerated with the Metal GPU) so your audio never leaves your machine. Press a hotkey, speak, and the text appears at the cursor — in any app.

100 % Local, 100 % Private

All processing happens on your Mac. No audio is ever uploaded, recorded, or shared. Mundwerk runs entirely on-device, even when you are offline. Your dictations stay yours.

Push-to-Talk Workflow

Hold the Fn key or a custom hotkey, speak, release. Mundwerk transcribes and types the text directly into the app you are working in — Mail, Notes, IDEs, browser fields, any text input.

German and English in One Stream

Mundwerk handles mixed-language input naturally. Technical English jargon, product names, and German prose flow together in a single dictation, without switching modes.

Learns Your Vocabulary

A correction memory and custom vocabulary let Mundwerk pick up names, project terms, and product-specific words over time. The more you use it, the sharper it gets.

One-Time Purchase

No subscription, no account required, no recurring fees. Buy once, dictate forever — with a fair update policy.

Designed for Apple Silicon

Mundwerk lives in the menu bar, ships universally for Macs from M1 onward, and uses Metal GPU acceleration via whisper.cpp for fast, low-latency transcription.
