Medical Dictation Software That Never Leaves Your Workstation
OpenWhispr is private, open-source medical voice dictation software for doctors and clinicians. Dictate clinical notes and SOAP notes straight into any EHR — and because transcription runs 100% on your device, patient audio never travels to the cloud.
The Problem with Most Medical Dictation Software
Clinical documentation is one of the biggest time sinks in medicine. Dictation should make it faster — but most dictation tools, including cloud speech services and many hosted medical solutions, stream your audio to remote servers for processing. When you are dictating a patient's diagnosis, medications, and history, that audio is some of the most sensitive data your practice handles.
Sending PHI to a third party creates a chain-of-custody problem. The audio crosses networks, lands on someone else's infrastructure, and falls under their retention and security policies. Even with a Business Associate Agreement in place, you are trusting an outside vendor with information you are obligated to protect — and you are often paying recurring per-seat or per-minute fees for the privilege.
OpenWhispr removes the cloud from the equation. Every word of audio is transcribed locally using OpenAI Whisper and NVIDIA Parakeet. Nothing leaves the machine — no network requests, no remote processing, no third-party retention of patient audio.
Built for Clinical Documentation, Kept on Your Device
100% Local Transcription
Speech-to-text runs on your workstation through OpenAI Whisper and NVIDIA Parakeet. Patient audio never touches a network. Disconnect from the internet and OpenWhispr dictates exactly the same — there is no cloud fallback and no "optional" data sharing for core transcription.
Dictate Into Any EHR Field
A system-wide push-to-talk hotkey types transcribed text into whatever field has focus — Epic, Cerner, athenahealth, any web-based EHR, your charting tool, or even email. No plugin, no integration project. If you can type into the field, you can dictate into it.
SOAP Notes via Agent Mode
Agent mode reshapes raw dictation into structured output using a custom system prompt. Build a SOAP-note prompt and speak the encounter naturally — it organizes your words into Subjective, Objective, Assessment, and Plan. The AI cleanup step is optional and can stay local-only for strict PHI handling.
Accuracy You Can Tune
Pick from multiple Whisper and Parakeet model sizes. Larger models handle dense clinical language and common medical terminology with high accuracy; smaller models are faster for quick notes. You decide the accuracy-versus-speed balance per machine — all running locally.
How Clinicians Use OpenWhispr Day to Day
Primary Care & Clinical Notes
After a visit, hold the hotkey and dictate the encounter: "45-year-old male presenting with acute lower back pain, onset two days ago, no radiating symptoms, negative straight-leg raise..." Agent mode can structure it into a SOAP note. Every bit of PHI stays on your workstation.
Therapy & Behavioral Health Session Notes
Between sessions, dictate your progress note while the conversation is fresh. Build an agent-mode prompt for your preferred format — DAP, BIRP, or a custom intake template. Sensitive session content never leaves your device, which matters enormously for behavioral health confidentiality.
Radiology-Style Reporting & Specialty Notes
Dictate findings and impressions in your reading workflow, then let agent mode lay them out in a consistent report structure. Whether it is imaging impressions, procedure notes, or specialist consults, the push-to-talk hotkey drops text straight into your reporting field — fully offline, fully local.
OpenWhispr vs. Dragon Medical & Cloud Dictation — Honestly
Dragon Medical and hosted cloud speech services have a real strength: vendor-curated medical vocabularies and years of clinical tuning. If your workflow depends on an out-of-the-box lexicon for obscure drug names and specialty abbreviations, that is a genuine advantage worth weighing. We are not going to pretend otherwise.
Where OpenWhispr wins is the architecture and the economics. Transcription happens on your device, so patient audio never leaves the workstation and there is no cloud STT service to send PHI to. The software is open source, so your IT and security teams can audit exactly what it does. And there are no per-minute cloud transcription fees, because there is no cloud transcription. The trade-off is that you tune accuracy by model size and may correct the occasional unusual term rather than relying on a proprietary medical dictionary.

Privacy Architecture — What OpenWhispr Does and Never Does
What OpenWhispr Does
- Transcribes patient audio entirely on your local device
- Uses OpenAI Whisper and NVIDIA Parakeet — no cloud STT calls
- Types into any EHR or text field via a global hotkey
- Stores transcription history locally only
- Works completely offline
- Is open source and auditable by your security team
What OpenWhispr Never Does
- Send patient audio to any external server for transcription
- Transmit transcripts over the network as part of core dictation
- Store PHI in any cloud service
- Require an internet connection to function
- Claim to be a certified or HIPAA-certified medical product
Honest nuance: agent mode's optional AI cleanup can use a cloud LLM API if you configure one — in that case the transcribed text you clean up would be sent to that provider. Core transcription is always local. For strict PHI handling, keep agent mode local-only or disabled. OpenWhispr is not a certified medical or compliance product, but because data never leaves the device, local processing supports the privacy obligations your practice is already responsible for. Confirm your full workflow with your own compliance team.
Open Source Means Your Team Can Verify It
Procurement and security reviews are part of bringing any tool into a clinical environment. Because OpenWhispr's entire codebase is public on GitHub, your IT security team, privacy officer, or an outside auditor can inspect exactly what the software does, confirm that transcription is local, and validate there is no hidden data exfiltration. No black boxes, no "trust us" — verify it yourself.
Frequently Asked Questions
Is OpenWhispr HIPAA compliant?
OpenWhispr is not a certified medical product and does not market itself as HIPAA-certified — no software can be. What matters technically is that OpenWhispr transcribes audio 100% locally on your workstation. Protected health information (PHI) is never transmitted to OpenWhispr servers or any cloud transcription service, so there is no third party to sign a Business Associate Agreement with for the core transcription step — there is simply no data to share. Because PHI never leaves the device, local dictation supports the privacy and confidentiality posture your practice is already responsible for maintaining. Always confirm your overall workflow with your own compliance team.
What is the best dictation software for doctors?
The right choice depends on your priorities. Cloud tools like Dragon Medical offer deep medical vocabularies but send audio off-device and carry recurring per-seat licensing costs. OpenWhispr takes a different approach: transcription runs entirely on your local machine using OpenAI Whisper and NVIDIA Parakeet models, it is open source and auditable, and it types into any text field in any EHR. If keeping PHI on the workstation, offline reliability, and transparency matter most to you, OpenWhispr is a strong fit. If you depend on a vendor-curated medical lexicon and a Business Associate Agreement for a cloud service, evaluate that trade-off carefully.
Does medical dictation work offline?
Yes. OpenWhispr's core transcription runs fully offline because the speech models live on your device. You can disconnect from the internet entirely and dictate clinical notes exactly the same way. This is useful in exam rooms with poor connectivity, in facilities with restricted networks, or anywhere you simply do not want audio leaving the machine.
Can OpenWhispr format SOAP notes?
Yes. Agent mode reformats your raw dictation into structured output using a custom system prompt you define. You can create a SOAP prompt that organizes what you said into Subjective, Objective, Assessment, and Plan sections. Note that agent mode's AI cleanup can optionally use a cloud LLM API if you configure one — for maximum privacy you can keep agent mode local-only or skip it entirely, since core transcription is always on-device.
How accurate is OpenWhispr for medical terms?
Accuracy scales with model size — the larger Whisper and Parakeet models produce noticeably better transcriptions of clinical language than the small, fast ones. OpenWhispr does not ship a vendor-curated medical lexicon the way Dragon Medical does, so unusual drug names, abbreviations, or specialty jargon may occasionally need correction. In practice, dictating clearly with a larger model handles the vast majority of common clinical terminology well. Dictate, glance at the output, and fix the rare miss.
Does OpenWhispr work inside Epic, Cerner, or other EHRs?
Yes. OpenWhispr uses a system-wide push-to-talk hotkey and types transcribed text directly into whatever text field has focus. That means it works in Epic, Cerner, athenahealth, any web-based EHR, your charting software, Word, or email — without an integration or plugin. If you can click into a field and type, you can dictate into it.
Is patient audio ever stored or uploaded?
Audio is processed locally and is not uploaded to OpenWhispr for transcription. Transcription history is stored locally on your device only. There is no cloud sync of audio or transcripts as part of core dictation. The one nuance to know: if you enable agent mode with a cloud LLM provider, the transcribed text you choose to clean up would be sent to that provider — so for strict PHI handling, keep agent mode local-only or disabled.
How much does OpenWhispr cost for a medical practice?
OpenWhispr is open source and there is no audio sent to a paid transcription service, so you avoid per-minute cloud STT fees. See the pricing page for current plan details. Because the software is auditable, your IT and security teams can review exactly what it does before any rollout.
