Mundwerk for doctors — documentation without cloud risk
· 5 min read · Privacy
For a doctor, medical confidentiality isn't a buzzword — it's professional law. Yet many practices use dictation tools where patient data ends up on third-party servers, often without realising it.
Mundwerk solves this problem.
The problem with cloud dictation
Most speech recognition apps — whether Apple Dictation, Google Voice, or cloud-based dictation services — send audio data or transcripts to external servers. For everyday notes that may be acceptable. For patient data, it's a GDPR problem.
Article 9 of the GDPR protects health data as a particularly sensitive category. Transmission to cloud services without explicit patient consent — which is rarely practical to obtain — is legally questionable. Supervisory authorities have already imposed fines for similar violations.
How Mundwerk changes the practice
With Mundwerk, every spoken word stays on the doctor's own Mac. Processing is handled by Whisper — OpenAI's leading speech model — fully offline. Not one byte leaves the device.
In daily practice, that looks like this:
- Anamnesis dictated directly into the EMR while the patient is still in the room
- Doctor's letters spoken instead of typed — at 3–4 letters per day, that saves 30–45 minutes
- ICD codes and medical terminology reliably recognised — including complex diagnoses

Medical terminology: where other solutions fail
Whisper — the heart of Mundwerk — is significantly more accurate on medical terminology than Apple's built-in dictation. Diagnoses like arteriosclerosis, hypothyroidism, or cholecystolithiasis are reliably recognised without tedious manual correction.
The learning function reinforces this advantage: correct a word once, and Mundwerk remembers the correction. Practice-specific vocabulary — drug names, internal abbreviations, common diagnoses — becomes increasingly accurate over time.
Limitations
Mundwerk runs exclusively on macOS with Apple Silicon. Anyone still working on Intel Macs or Windows needs a different solution.
Mundwerk is also not specialised practice software: there's no EMR integration, no structured dictation templates, no automatic forwarding into document management systems. It's a universal dictation tool — which happens to also work very well for medical documentation.
Conclusion
For practices that take privacy seriously, Mundwerk isn't an alternative — it's the only sensible choice among available Mac dictation solutions. The combination of Whisper quality, fully offline processing, and one-time purchase price makes it the privacy-compliant foundation for daily documentation.
