LumeVoice vs Superwhisper (2026): Best Mac Dictation for Privacy?

If you care about local privacy on your Mac, you know Superwhisper. It made "on-device Whisper" dictation practical and built a loyal following among privacy-minded developers, lawyers and researchers.

LumeVoice takes a different approach: cloud processing, with audio not stored after processing and never used for training, plus automatic cleanup that turns rambling speech into finished text. If you handle sensitive legal documents, patient notes or proprietary code, which one should you run?

Here's how they differ, based on how each app works and what each company documents. We don't quote speed or accuracy scores, because those depend on your Mac, your connection and your voice; where the answer depends on your setup, we say so.

Head-to-Head at a Glance#

Prices as of October 2026; vendors change them, so check their sites.

1. Ease of Use & Configuration#

A tool is useless if it's too annoying to set up.

• Superwhisper: Built for tinkerers. You choose your exact model, create modes for different kinds of writing and write the instructions its AI follows. The configurability is its selling point, and its learning curve: to get genuinely good results, you need to spend time building and maintaining your modes.
• LumeVoice: Built to work out of the box. Hold fn on a Mac (Ctrl + Win on Windows) and talk, or double-press it for hands-free mode, and the finished text is typed into whatever app has your cursor. Cleanup is on by default; a custom dictionary, snippets and writing styles are there when you want more control.

Winner: LumeVoice (for most users), Superwhisper (for tinkerers who want granular control)

2. Speed: What It Depends On#

Neither app's speed is a single number, and a figure measured on someone else's Mac and connection tells you little about yours.

• Superwhisper: With local models, the work happens on your Mac. Smaller models return text quickly; larger ones are more accurate but take longer and use more memory, and an older or 8 GB Mac feels that more than a recent MacBook Pro. You can always trade some accuracy for speed by choosing a smaller model.
• LumeVoice: The work happens in the cloud, so your Mac does very little and the main variable is your internet connection. On a slow or patchy connection, local processing has the edge; with no connection at all, only local works.

Winner: Depends on your Mac and your connection

3. Privacy and Offline Use#

Can you use it securely on a plane, in a hospital, or when reviewing privileged legal documents?

• Superwhisper: Fully local with local models: audio never leaves your device, and dictation works offline. If you choose a cloud model instead, that audio goes to the cloud, so choose deliberately for sensitive work.
• LumeVoice: Cloud processing only. Audio isn't stored after processing and is never used for training, and your dictation history stays on your device. But audio is transmitted for processing, so this is a promise about storage rather than about transmission, and there's no offline mode.

The key distinction: LumeVoice does not offer an on-device mode. For work that cannot leave the machine, or for dictating without a connection, Superwhisper is the correct choice.

Winner: Superwhisper

4. Memory: The "8 GB Mac" Reality#

This matters if you're running an M1 or M2 MacBook Air with 8 GB of memory.

• Superwhisper: A local speech model has to be loaded into memory while it runs, and the larger the model, the more memory and processing it needs. On an 8 GB Mac that competes with Chrome, Slack, VS Code and Notion; on a Mac with 16 GB or more you're much less likely to notice. Choosing a smaller model eases the load.
• LumeVoice: Doesn't run a speech model on your Mac at all, so its footprint doesn't grow with model size.

For MacBook Air owners who want the largest models, that's a practical difference.

Winner: LumeVoice on low-memory Macs; a tie on well-equipped ones

5. Text Intelligence#

What happens after your words are transcribed?

• Superwhisper: Its plain voice-to-text gives you what you said. AI modes can format and tidy the text according to instructions you write, which is powerful, but it's something you choose, configure and maintain.
• LumeVoice: Cleans up automatically. It removes filler words ("um", "uh", "you know", "like" used as a pause), applies self-corrections ("seven, actually no, nine" becomes "nine"), turns spoken lists into numbered lists, converts spoken punctuation commands, and fixes grammar and spelling.

Winner: LumeVoice (for cleanup by default), Superwhisper (if you want to write the rules yourself)

6. Pricing#

• Superwhisper: A free tier with limits, then Pro at $8.49/month, $84.99/year or $249.99 one-time. All three paid plans have the same features.
• LumeVoice: Pro Monthly ($14.99/mo), Pro Annual ($79.99/yr, about $6.66 a month) or Lifetime ($249 once). Every new account starts with 3,000 free words, no card required, you get a 7-day free trial when you first upgrade in the app (card required), and students pay $39.99 a year or $7.49 a month.

Both sell a lifetime licence, and both now run on Mac, Windows, iPhone and Android, so the decision comes down to what you're paying for: local, offline, configurable dictation, or cloud dictation with cleanup by default.

Who Should NOT Choose Superwhisper#

• You want plug-and-play with zero configuration
• You want filler words and self-corrections handled by default
• You're on an 8 GB Mac and want the largest local models alongside a full set of apps

Who Should NOT Choose LumeVoice#

• Your audio must never leave your device, or you need to dictate offline
• You genuinely enjoy building custom modes and choosing your own models
• You mainly transcribe pre-recorded audio and want it done offline (MacWhisper is built for that; LumeVoice's desktop apps transcribe audio and video files too, but in the cloud)
• You want raw, unmodified transcription without any cleanup layer

The Verdict#

Run Superwhisper if:

• Audio must stay on your device, or you dictate without a connection
• You want to build and tweak your own modes and choose your models

Run LumeVoice if:

• You want clean, ready-to-send text without configuring anything
• You're on a low-memory Mac and don't want a large model running locally
• Cloud processing, with audio not stored afterwards, is acceptable for your work
