Mundwerk
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.
Features
What it does
100 % local, 100 % private
All processing happens on your Mac. No audio is uploaded, recorded, or shared — even 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 into whatever app you are in — Mail, Notes, IDEs, browser fields.
German and English in one stream
Mixed-language input is handled naturally. Technical English jargon, product names, and German prose flow together in a single dictation, no mode switching.
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, no recurring fees. Buy once, dictate forever — with a fair update policy.
Designed for Apple Silicon
Lives in the menu bar, ships universally for Macs from M1 onward, and uses Metal GPU acceleration via whisper.cpp for low-latency transcription.
