What is the difference between cloud and local medical scribe software?

Cloud medical scribes (Freed, DeepScribe, ScribeMD, Heidi Health, Suki, Nuance DAX) record the physician-patient encounter and upload that audio to remote servers for AI processing. The AI generates clinical notes from the conversation. Local medical scribe software processes audio entirely on the physician's own device — no audio is transmitted to any server. The two approaches differ primarily in how the physician documents: ambient capture vs. directed dictation.

Do cloud medical scribes require a HIPAA Business Associate Agreement?

Yes. Cloud medical scribes receive and process protected health information on their servers, which makes them HIPAA business associates. A signed Business Associate Agreement is required before clinical use. Vendors typically provide a BAA, but it adds procurement overhead and creates a legal relationship that must be maintained. Local on-device tools like VoicePrivate do not receive or store patient audio, so no BAA is required.

Which is more accurate — cloud AI scribes or local dictation?

Cloud ambient scribes often produce more complete clinical notes because they capture the full patient-physician conversation. For physicians who want the AI to listen and document without active dictation, cloud scribes have an advantage in note completeness. Local dictation tools like VoicePrivate are more accurate per word for directed dictation, with 99.3% accuracy on medical terminology, but they require the physician to speak the note rather than have the AI infer it from conversation.

Does VoicePrivate work with EHRs like Epic and Cerner?

VoicePrivate types text directly into any application on the physician's Mac or Windows computer, including web-based EHRs. It works with Epic Hyperspace, Cerner, Athenahealth, SimplePractice, TherapyNotes, and any other system accessible through a browser or desktop app. It does not require a native EHR integration — it works at the operating system level.

Cloud vs. Local Medical Scribe Software

Two different approaches to clinical documentation. One sends patient audio to a server. The other keeps everything on your device. Here is what actually matters when you're choosing between them.

How Cloud Medical Scribe Software Works

Cloud ambient scribes — Freed, DeepScribe, ScribeMD, Heidi Health, Suki, Abridge, Nuance DAX — are designed to listen to the physician-patient encounter and generate clinical notes automatically. The workflow is roughly: the physician opens the app before seeing a patient, presses record, conducts the visit normally, and then the AI produces a draft note for review and sign-off.

The core architecture behind all of these tools is the same: your microphone captures the conversation, and that audio is streamed or uploaded to the vendor's cloud infrastructure. A large language model processes the audio on remote servers, identifies clinical information, structures it into a note format (SOAP, DAP, etc.), and returns the draft to your device.

The appeal is obvious. Physicians don't have to actively dictate. The documentation happens in the background. In high-volume clinical settings where documentation burden is a major source of burnout, that matters.

What this means for your data

Patient audio — including everything spoken during the clinical encounter — exists on a third-party server during and after processing. The vendor's data retention policy, security posture, and breach history are all factors in your exposure. Under HIPAA, this relationship requires a signed Business Associate Agreement before you start using the tool clinically.

How Local On-Device Medical Scribe Software Works

Local medical dictation software takes a different approach to the same documentation problem. Instead of listening to the full patient encounter and generating a note, it gives the physician a fast, accurate voice input tool for dictating notes directly.

With VoicePrivate, the workflow is: see the patient, then immediately after the visit (or during, if preferred), open the app, dictate the note by speaking, and have it typed directly into your EHR or notes application. The AI model that converts your speech to text runs entirely on your own Mac or Windows machine. Nothing is transmitted anywhere.

The trade-off is real and worth naming clearly: local dictation requires the physician to actively speak the note. It does not listen to the visit and generate documentation on its own. For physicians who want a fully passive documentation experience, local dictation is not that.

What this means for your data

Because audio never leaves your device, there is no vendor data custody issue. No BAA is required — VoicePrivate is not a HIPAA business associate because it never receives or processes protected health information. Patient audio stays on your hardware and nowhere else.

When Cloud Ambient Scribes Are the Right Choice

Cloud ambient scribes are well-suited to specific clinical scenarios. Being honest about this matters more than a one-sided comparison.

High-volume practices with strong IT infrastructure. Large health systems and hospital groups that can negotiate enterprise BAAs, conduct security assessments, and manage vendor relationships at scale are the target buyer for tools like Nuance DAX and DeepScribe. The documentation automation ROI is clearest where documentation burden is highest and where the compliance infrastructure already exists.
Physicians who want passive documentation. If the goal is to eliminate active dictation entirely and have the AI generate notes from the conversation without any physician input, cloud scribes are designed for that. Local dictation is not.
Complex, long encounters where note structure matters most. Ambient scribes trained on clinical conversation data may do a better job of inferring the structured elements of a note (chief complaint, HPI, assessment and plan) from natural dialogue than a physician would produce in rapid dictation.

When Local On-Device Dictation Is the Right Choice

There is a large segment of clinical practice where the cloud ambient scribe model creates more problems than it solves.

Solo and small practices without compliance infrastructure. A single-physician practice or a five-clinician group typically does not have an IT department, a privacy officer, or a process for managing vendor BAAs. Using a cloud scribe without a properly executed BAA and documented security risk assessment is a HIPAA compliance exposure. Local dictation removes the compliance overhead entirely.
Physicians who can't have patient conversations recorded. Some clinical specialties and patient populations make ambient recording impractical or inappropriate. Psychiatry, therapy, and addiction medicine involve highly sensitive disclosures where patients may reasonably object to being recorded. Local dictation — where you speak the note after the visit — eliminates the ambient recording problem.
Clinical environments without reliable internet. Rural clinics, correctional facilities, community health centers with limited connectivity, and physicians who travel between sites cannot depend on a cloud-connected tool. Local dictation works offline, always.
Organizations under strict data governance requirements. Government health services, military medicine, and clinical research settings may operate under policies that prohibit sending patient data to commercial cloud vendors regardless of BAA status. Local processing is the only architecture that satisfies these requirements.
Cost-sensitive practices. At $34.99/month, VoicePrivate Healthcare Edition costs less per year than a single month of most enterprise cloud scribe contracts. For independent practitioners, that gap is significant.

The HIPAA Dimension in Plain Terms

The HIPAA question comes up constantly in medical scribe software comparisons. Here is a straightforward summary, not legal advice.

Under HIPAA, a business associate is any entity that creates, receives, maintains, or transmits protected health information on behalf of a covered entity. Cloud medical scribes do all four. They receive audio containing patient names, diagnoses, medications, and treatment discussions. A signed BAA is legally required before clinical use begins.

Most cloud scribe vendors offer a standard BAA as part of their service. Having one is better than not having one. But the BAA does not eliminate the data exposure — it creates a legal framework for managing it. The vendor still has your patient audio on their servers. Breaches at cloud vendors are real events with real consequences for the covered entities that signed BAAs with them.

The on-device alternative

VoicePrivate's design is different: because patient audio never leaves the physician's device, VoicePrivate is not a business associate and no BAA is required. There is no covered relationship because there is no covered data transfer. This is not a workaround — it is a different architecture that eliminates the data custody issue rather than managing it.

Medical Scribe Software: Structured Decision Framework

If you are evaluating medical scribe software and trying to decide between cloud and local options, these questions will narrow the field quickly.

Choose cloud ambient scribes if:

Your practice or health system has a functioning BAA management process
You want documentation to happen without active physician input during or after the visit
You have consistent, reliable internet connectivity in all clinical environments
Your patients are generally comfortable with ambient recording (or explicit consent is part of your intake process)
Budget is not a primary constraint

Choose local on-device dictation if:

You are a solo or small-group practice without a compliance infrastructure for managing vendor BAAs
You cannot or prefer not to have patient encounters recorded by a third-party tool
You need offline capability — rural, restricted network, field-based clinical work
Your organization prohibits cloud data transfers for patient information
You want predictable, publicly posted pricing without a procurement process
You prefer to control what goes into the note directly rather than relying on AI inference from conversation
