VoicePrivate vs
Wispr Flow
VoicePrivate processes 100% on your device — zero cloud, zero screenshots, zero data collection. Wispr Flow sends your audio to cloud servers and captures screenshots of your screen for "context." Here's the full picture.
The cloud privacy model — what changes
The difference is architectural, not cosmetic.
Why cloud dictation changes the trust model
Wispr Flow's current product documents describe cloud transcription as the default path. That means your dictated voice data is processed on remote servers rather than staying entirely on your machine.
Wispr also offers additional privacy controls such as Privacy Mode, Zero Data Retention, and HIPAA / BAA support. Those controls matter, but they are settings and contractual safeguards layered on top of a cloud architecture, not a fully local default.
For many users that trade-off is acceptable. For regulated or highly sensitive workflows, it means you should evaluate remote processing, retention settings, and optional context-aware features much more carefully.
Two fundamentally different architectures
The difference isn't a feature — it's the foundation.
VoicePrivate (On-Device)
- Audio captured by microphone, held in RAM
- Local transcription runs on your device's CPU/GPU
- Optional grammar polish by local LLM (also on-device)
- Text pasted into your app
- Audio discarded from RAM
- No network connections opened during transcription
- No screenshots taken
- No server exists
- Works fully offline
- Verifiable: run a network monitor and see zero traffic
Wispr Flow (Cloud)
- Audio recorded and sent to Wispr's cloud servers
- Optional context-aware features read nearby app content
- Cloud transcription and cloud AI providers shape final output
- Text sent back to your device
- Audio may be retained per privacy policy
- Internet connection required for cloud transcription
- SOC 2 certified
- Multiple third-party subprocessors handle your data
- HIPAA workflows supported with BAA + Zero Data Retention
- Privacy depends on product settings and vendor controls

Where Wispr Flow is ahead
We believe in honest comparisons.
Context-aware formatting
Wispr detects your active app and nearby context to adjust formatting automatically. That is a real usability advantage, especially for email and chat workflows.
Voice command editing
Say "make this more formal" or "turn into bullet points" and Wispr transforms your text. This requires cloud AI processing — a feature we're building with local LLM support.
iOS support
Wispr supports Mac, Windows, iOS, and Android. VoicePrivate currently focuses on desktop on macOS and Windows.
Team features
Wispr offers team plans with shared dictionaries and admin controls. VoicePrivate is currently single-user focused.
The trade-off
Wispr Flow's context-aware and cloud-editing features are genuinely useful. But their cloud transcription path sends dictation to remote servers, and optional context features inspect nearby app content to improve output. That's the trade-off:
Do you want cloud-assisted dictation with context-aware features, or a tool that keeps transcription fully local on your machine by default?
If you dictate personal notes, medical records, legal documents, financial data, or anything you wouldn't paste into a public chatbot — the answer matters.
