The Cloud Compromise

The Problem with Cloud Dictation

Mental health, psychiatric evaluations, and sensitive clinical consultations require absolute patient confidentiality. Traditional cloud dictation apps upload audio to third-party servers, creating significant data breach exposure and regulatory overhead under HIPAA privacy and security rules.

Target Profile: Therapists, psychologists, psychiatrists, primary care clinicians, and medical scribes
The Local-First Solution

Physical Hardware Sovereignty

Murmur is engineered with an air-gapped security model. Voice recognition runs locally on your workstation's Apple Silicon Neural Engine or NVIDIA/AMD DirectX GPU. No remote APIs are called, and all temporary recording buffers are instantly sanitized upon completion.

Frequently Asked Questions

Does Murmur store my patient notes?

No. Murmur transcribes spoken audio into memory and immediately inserts the formatted text into your open documentation tool or EHR. It does not upload or retain patient notes on external servers, and local retention can be set to immediate purge.

Does Murmur sell data to healthcare analytics vendors?

No. Murmur is an open-source tool with zero tracking, zero external telemetry, and no business model based on data monetization. All code is auditable on GitHub.

Can clinical staff verify that zero data leaves the computer?

Yes. Because Murmur is fully open source and runs locally, healthcare IT staff can monitor the process with Wireshark, Little Snitch, or Windows Packet Monitor to independently confirm that zero bytes are transmitted during dictation.

How does Murmur compare to cloud clinical voice apps?

Cloud clinical voice apps require network connectivity, cost monthly subscriptions, and introduce third-party vendor risks. Murmur runs at lower latency (<200ms) with zero subscription fees and zero cloud exposure.
