Voibe vs Wispr Flow vs superwhisper: The Best Private Mac Dictation App in 2026

If you want to dictate on a Mac without your voice ending up on someone else’s server, three names come up again and again: Voibe, Wispr Flow, and superwhisper. We tested all three the way you’d actually use them — drafting emails, notes, and documents during real work — and judged them on the one thing a privacy-minded professional can’t compromise on: does your audio stay on your machine?

The short answer

For most people who need private dictation, Voibe is the pick. It processes everything on-device, works system-wide in any app, is the simplest to live with, and is priced fairly with a lifetime option. superwhisper is the power-user’s choice if you like tinkering with local models. Wispr Flow is fast and polished but leans on the cloud, which is a dealbreaker if privacy is the whole point.

How we judged them

Four things, in order: privacy architecture (is speech processed on-device, and is any audio stored or uploaded?), accuracy on real dictation, speed from the moment you stop talking to text on screen, and how it feels day to day — setup, whether it works everywhere, and price.

At a glance

Voibe — the privacy-first default

Voibe does one thing and does it cleanly: you hold a key, talk, release, and your words appear in whatever app you’re in. The transcription runs entirely on-device using on-Mac Whisper models tuned for Apple’s Neural Engine, so nothing is recorded, stored, or uploaded. In practice it’s fast — text lands almost the instant you stop — and it stays out of your way. It supports 90+ languages and plugs into tools like Cursor and VS Code, which developers will appreciate. Pricing is refreshingly normal: $7.50/mo, $59/yr, or a $149 one-time lifetime license, with a 7-day trial and a 30-day money-back guarantee. Check current Voibe pricing →

Wispr Flow — fast, but cloud-leaning

Wispr Flow is genuinely slick and quick, with strong formatting smarts. The catch for this audience is its reliance on cloud processing. If your dictation includes anything privileged or confidential, sending audio off-device is exactly what you’re trying to avoid — and it’s why Wispr Flow lands behind the two on-device options here despite being a good product.

superwhisper — the power user’s tool

superwhisper also runs local models on-device, so it clears the privacy bar. It gives you more control — different model sizes, modes, and configuration — which is great if you enjoy dialing things in, and slightly more to manage if you just want to talk and go. If you’re technical and want to tune your own local setup, it’s excellent.

Which should you choose?

Want private dictation that just works? Voibe. Want maximum control over local models and don’t mind setup? superwhisper. Prioritize raw speed and formatting over keeping audio on-device? Wispr Flow — but know the tradeoff. For lawyers, clinicians, therapists, journalists, and anyone who can’t risk their audio touching a third-party server, on-device is non-negotiable, and Voibe is the easiest way to get there.

FAQ

Does offline dictation really keep my audio private?

With a truly on-device app like Voibe or superwhisper, yes — speech is converted to text locally and no audio is uploaded or stored. Always confirm an app is processing on-device before trusting it with sensitive material.

Is on-device dictation as accurate as cloud?

Modern on-device Whisper models are very accurate for everyday professional dictation. For most email, notes, and document work you won’t notice a meaningful gap.

Which is best for lawyers and healthcare?

An on-device tool that never uploads audio. Voibe is our top recommendation for these fields because it’s fully offline and simple to deploy.
