Zero-Cloud Voice Dictation forMedical Professionals.
Dictate patient charts, clinical summaries, and consultations directly into your EHR cursor. Audio and clinical records process 100% on your local workstation GPU with zero cloud uploads.
Regulatory & Compliance Disclaimer: Murmur is not a certified HIPAA Business Associate and makes no healthcare-specific compliance claims or medical certification representations. Murmur is general-purpose, open-source local dictation software engineered to process all audio and text strictly on-device with zero external network transmission.
The Problem with Cloud Dictation
Legacy clinical dictation systems and cloud AI scribes stream patient conversations across remote internet servers. This requires complex Business Associate Agreements (BAAs), exposes healthcare providers to catastrophic breach liabilities, and subjects sensitive encounters to third-party cloud data retention.
Physical Hardware Sovereignty
Murmur executes OpenAI Whisper open weights directly on your workstation's local GPU via whisper.cpp. Audio streams exist purely in temporary RAM and are erased the moment text is typed into your EHR. With built-in Air-Gap Mode, all outbound network sockets are hard-killed.
Local Architecture vs. Cloud SaaS
| Buyer Concern | Murmur (Local-First) | Cloud Alternatives (e.g. Wispr) |
|---|---|---|
Audio Transmission Vector Eliminates man-in-the-middle attacks and external breach liability | 0 Bytes (Never leaves physical workstation) | Streamed to external cloud clusters over public internet |
Third-Party Data Access Minimizes security surface area and simplifies IT audits | None (Zero servers, zero vendor analytics) | Cloud infrastructure providers, sub-processors, and vendors |
Retention & Auto-Purge Enforces strict organizational sanitization schedules | User-configurable (Auto-purge on lock screen & daily retention sweep) | Default cloud database storage with opaque deletion timelines |
EHR Cursor Insertion Works seamlessly in Epic Hyperdrive, Cerner Millennium, and desktop charts | Native OS accessibility injection across all EHR applications | Proprietary browser extensions or isolated web portals |
Clinical documentation speed shouldn't compromise patient confidentiality.
Medical practitioners spend up to 2 hours per day on EHR documentation. Murmur delivers instantaneous voice typing at over 150 words per minute while keeping all patient interactions confined to your physical machine.
“Murmur lets me dictate patient visit summaries directly into Epic twice as fast as typing, and our hospital IT team approved it immediately because zero network packets leave my machine.”
How to Verify This Claim Yourself
Run Windows Packet Monitor (pktmon) or macOS LuLu while dictating a test clinical note. Verify that zero outbound network traffic is generated during recording and transcription.
Frequently Asked Questions
Does Murmur store my patient notes?
No. By default, Murmur operates in-memory in RAM and types directly into whichever application window holds your cursor. Any optional local history database can be configured with an automated retention purge (e.g. 1 day, or disabled entirely), and Murmur automatically clears in-memory buffers when your computer is locked.
Does Murmur sell data to healthcare analytics vendors?
No. Murmur contains zero telemetry, zero analytics trackers, zero advertisements, and zero remote connections. There are no corporate servers or data pipelines collecting user information.
Does Murmur require a Business Associate Agreement (BAA)?
A HIPAA BAA is legally required when a third-party vendor creates, receives, maintains, or transmits Protected Health Information (PHI) on your organization's behalf. Because Murmur never receives, transmits, or hosts any of your data, it acts as local workstation software rather than an external data processor. Please note Murmur makes no official compliance claims; consult your organization's compliance officer.
How does Murmur handle medical terms and drug names?
Murmur includes custom phonetic dictionary support. You can add complex medical terminology, generic pharmaceuticals, anatomical terms, or clinic-specific acronyms to ensure consistent, accurate transcription.
