VoicePrivate is a voice-to-text app for Mac that processes everything on your device. No cloud uploads. No account. Works offline after the first model download. Live dictation types into any app in real time; file transcription handles audio and video via drag-and-drop.

Five domain-specific editions — Healthcare, Legal, Finance, Insurance, General — cover the specialized vocabulary of each field out of the box. Custom vocabulary, speaker diarization, and AI command mode extend from there. One model download on first run, then fully offline. Free tier available; no credit card required to start.

What VoicePrivate Does

• On-device, offline, zero cloud — audio never leaves your Mac, no account required, no telemetry
• Live dictation into any Mac app — types directly into Slack, Word, Notion, Mail, VS Code, Pages, or any text field
• File transcription via drag-and-drop — audio and video both supported, processed locally
• Speaker diarization — identifies and labels each speaker in multi-person recordings (paid plans)
• Custom vocabulary — add names, acronyms, brand terms, and domain jargon the engine learns to recognize
• Five editions: General, Healthcare, Legal, Finance, Insurance
• Export formats: .txt, .json, .md, .srt, .vtt

Free tier covers basic transcription and live dictation. Paid plans unlock diarization, longer files, additional export formats, and specialty editions. See the pricing page for current plan details.

Who This Is For

VoicePrivate is built for:

• Professionals dictating client notes, clinical documentation, or legal drafts — where audio privacy is not optional
• Privacy-conscious Mac users who do not want voice data stored or processed off-device
• Power users who have outgrown Apple Dictation — no file transcription, no speaker identification, no domain vocabulary
• Mac users in healthcare, legal, finance, or insurance who need terminology accuracy without building a custom model from scratch

macOS Dictation vs. VoicePrivate: What the Comparison Actually Looks Like

Most power users hit the same frustration: Apple Dictation works well enough for short bursts, then falls short the moment you push it harder. Here's where the gaps actually show up.

macOS Built-In Options

macOS includes built-in Dictation (System Settings → Keyboard → Dictation) and Voice Control (System Settings → Accessibility). For a full setup walkthrough and privacy comparison, see our guide to Mac dictation.

Feature Comparison

Bottom line: Apple Dictation is a solid free tool for general use. VoicePrivate is built for users who need more control — over their data, their output format, and their accuracy for specialized vocabulary.

Setting Up VoicePrivate

Setup is a single one-time model download on first launch. After that, the app works completely offline — no internet connection needed, ever. Open the app, pick your mode (file transcription or live dictation), and you're ready. No account to create. VoicePrivate has a free tier covering basic transcription, so you don't need a subscription to start.

Privacy and Data Handling: What Happens to Your Voice

VoicePrivate processes everything on your device. Your audio never leaves your machine. No cloud uploads, no telemetry, no account to associate data with.

This matters most in four situations:

• Healthcare: Patient conversations, clinical notes, and intake sessions contain protected health information (PHI). Sending that audio to a cloud server — even encrypted — creates compliance risk.
• Legal: Attorney-client privilege applies to the content of conversations. Cloud transcription introduces a third party.
• Finance: Earnings calls, client advisory discussions, deal conversations — material non-public in some contexts.
• General privacy: Some people simply don't want a tech company storing recordings of their voice. That's a valid position, and it doesn't require a compliance justification.

VoicePrivate's privacy architecture is the direct answer to all four. The Healthcare edition adds domain-specific medical vocabulary on top of the same on-device foundation.

Power-User Voice to Text Mac Features

Real-Time Dictation Into Any Mac App

VoicePrivate's live dictation mode types directly into whatever app is active — Slack, Notion, Word, Pages, Mail, VS Code, any text field. You speak, the text appears at your cursor in real time. No copy-paste step, no intermediate window. For detail on how latency is handled and what to expect in practice, see Real-Time Voice to Text on Mac: Latency, Accuracy, and How It Works.

Speaker Diarization

Diarization identifies and labels each speaker in multi-person recordings — "Speaker 1," "Speaker 2" — throughout the transcript. Useful for meetings, interviews, and any recorded conversation where a wall of undifferentiated text isn't useful. Available on paid plans.

Custom Vocabulary

General speech recognition stumbles on names, acronyms, and domain jargon. VoicePrivate lets you add terms so the engine recognizes them correctly — drug names, case citations, ticker symbols, or any field-specific language that matters to you. Covered in depth in Custom Vocabulary in Mac Voice-to-Text: Adding Names, Jargon, and Acronyms.

File Transcription and Export Formats

Apple Dictation works in real time only — there's no way to drop a file on it and get a transcript back. VoicePrivate handles drag-and-drop file transcription for audio and video, processed entirely on-device. On Apple Silicon, the Neural Engine makes long files fast. Export to .txt, .json, .md, .srt, or .vtt. For batch workflows, see Batch Audio Transcription on Mac: Transcribe Multiple Files Offline.

AI Command Mode

After transcription, AI command mode lets you transform the output with plain-language instructions: summarize, extract action items, reformat as bullet points. The transformation runs on-device — your content stays local even through post-processing.

Per-App Transcription Modes

VoicePrivate supports per-app transcription modes, so dictation behavior — vocabulary, formatting, and output style — can be configured for each context. What works in your email client can be tuned separately from how it behaves in a code editor.

Five Domain-Specific Editions

Beyond custom vocabulary, VoicePrivate ships five separate editions — General, Healthcare, Legal, Finance, and Insurance — each with a vocabulary set pre-tuned for that domain. The engine already knows the terminology common in your field; you're not starting from scratch.

Platform Requirements

VoicePrivate runs on macOS 13 (Ventura) and later. Both Apple Silicon (M1 and later) and Intel Macs are supported.

On Apple Silicon, the M-series Neural Engine handles the AI model processing — that's why transcription is fast enough for real-time use and long file batches. Intel Macs run VoicePrivate without issue, but if you're choosing a machine for heavy transcription work, Apple Silicon is the faster option. No web app or mobile app. macOS only.

Getting Started: Free Tier and Paid Plans

VoicePrivate has a free tier that covers basic transcription — enough to test on-device accuracy and live dictation with your own voice, microphone, and typical content before committing to a plan.

Paid subscription plans unlock:

• Speaker diarization
• Longer file transcription
• Additional export formats (.json, .md, .srt, .vtt)
• Specialty editions (Healthcare, Legal, Finance, Insurance)

See the pricing page for current plan details, and the FAQ if you have questions about what's included at each tier.
