Your voice never
leaves your Mac.
Every word you speak is processed entirely on your device by Voxtral AI from Mistral — an open-source model running on Apple Silicon. No cloud servers. No API calls. No data collection. Ever.
Why offline-first?
Cloud-based dictation tools send your raw audio to remote servers for processing. That audio can contain passwords, financial data, medical information, trade secrets — everything you say. We chose a fundamentally different architecture.
Architectural Privacy
It's not a policy choice — it's a design guarantee. EdgeWhisper physically cannot send your data anywhere because the AI runs entirely on-device. There is no server to send data to.
Works Without Internet
After the one-time AI model download, EdgeWhisper works completely offline. Airplane mode, coffee shop without WiFi, classified facility — dictate anywhere, anytime.
Zero Data Collection
No audio recordings. No transcription logs. No usage analytics. No telemetry. No cookies. No device fingerprints. We engineered the app to collect absolutely nothing.
The problem with cloud dictation
Every cloud-based dictation tool shares the same fundamental flaw: your voice has to leave your device.
Your audio is on someone else's server
Cloud dictation services receive your raw audio stream. Even with encryption in transit, your voice data is decrypted and processed on servers you don't control.
Data can be retained for training
Many services use your audio to improve their models. Your private conversations, medical notes, and legal documents may become training data.
Vulnerable to breaches
Any data stored on remote servers can be breached. Voice data is uniquely sensitive — it's biometric, containing your identity, emotions, and context.
Requires constant connectivity
No internet? No dictation. Cloud services fail when you need them most — on flights, in remote areas, or in secure facilities.
How EdgeWhisper is different
Privacy isn't a feature we added. It's the foundation we built on.
Proprietary, closed-source model on remote servers
Voxtral Mini 4B from Mistral AI — open-source (Apache 2.0), runs locally
Audio streamed to cloud, processed on third-party infrastructure
Processed in-memory on Apple Silicon's Neural Engine, never leaves RAM
Always — no internet means no dictation
Never — fully offline after one-time model download
Audio, metadata, usage patterns, device identifiers
Nothing — zero telemetry, zero analytics, zero tracking
Email, password, often phone verification
None — download and start dictating immediately
Depends on vendor's data handling practices
Inherently compliant — no data leaves the device to regulate
Closed-source, trust the vendor's claims
Open-source AI model, verifiable architecture, transparent processing
Built for people who care about privacy
If your words matter, they should stay yours.
Healthcare Professionals
Dictate patient notes, clinical observations, and medical records without HIPAA concerns. Nothing leaves your Mac.
Legal Professionals
Draft contracts, case notes, and client communications. Attorney-client privilege stays intact because no third party ever processes your audio.
Developers & Engineers
Dictate code comments, documentation, and Slack messages. No risk of proprietary code or architecture discussions leaking to cloud servers.
Journalists & Writers
Protect your sources. Draft sensitive stories. No cloud service can be subpoenaed for audio that never left your computer.
Business Executives
Dictation during board prep, M&A discussions, and strategy sessions. Your competitive intelligence stays on your device.
Security-Conscious Users
Anyone who values privacy. Passwords, financial discussions, personal reflections — keep it all local.
Technical guarantees
Don't take our word for it. Verify it yourself.
Open-Source AI Model
EdgeWhisper uses Voxtral Mini 4B Realtime from Mistral AI, released under the Apache 2.0 license. The model weights, architecture, and training methodology are publicly available on Hugging Face for anyone to audit.
View model on Hugging Face →Apple MLX Framework
The model runs via Apple's MLX framework — a machine learning framework for Apple Silicon. This is Apple's own technology, optimized for on-device inference with no cloud component.
Learn about MLX →macOS App Sandbox
EdgeWhisper runs inside macOS's App Sandbox, restricting what the app can access. It only requests Microphone (for voice capture) and Accessibility (for text injection) — nothing else.
Read our privacy policy →Zero Network Calls
After the initial model download from Hugging Face, EdgeWhisper makes zero network requests. You can verify this with any network monitoring tool like Little Snitch or Wireshark. Try it — you'll see nothing.
“We didn't build EdgeWhisper to be private — we built it so that privacy is the only possible outcome. When the AI runs entirely on your Mac, there is no server to breach, no data to sell, and no policy to violate.”
