If you want to transcribe audio on your own computer without sending it to anyone's server, you need a local Whisper app. Three names come up repeatedly: MacWhisper, Buzz, and Whisper Desktop.
One thing to know up front: they don't all run on the same system. MacWhisper is Mac only, Whisper Desktop is Windows only, and Buzz runs on Mac, Windows and Linux. So your operating system may make half the decision for you.
They all run Whisper models, so this isn't really an accuracy comparison. It's about platforms, polish, features, and whether you should pay.

The Thing That Matters More Than Which App#
All three run the same family of Whisper models. Your model choice affects speed and accuracy far more than your app choice.
| Model | Size | Practical RAM | Notes |
|---|---|---|---|
| Small | ~500MB | 8GB | Sensible default on 8GB |
| Medium | ~1.5GB | 8–16GB | Best balance for most |
| Large-v3 | ~3GB | 16GB+ | Accents, jargon, noisy audio |

Running Large-v3 on an 8GB laptop can push other apps into swap and make any of these tools feel sluggish. Hardware matters too: on a Mac, whisper.cpp-based apps use Apple's Metal GPU framework, so Apple Silicon is far quicker than an Intel Mac with the same model. On Windows, Whisper Desktop runs Whisper on your graphics card, so the GPU you have counts.
Get that right first, then pick an app.
1. MacWhisper — the polished option#
The best-looking of the three, and the one many Mac users settle on.
Free version: one file at a time, and some models are only fully available in Pro. Genuinely usable for short, clear recordings.
Pro (€65 one-time, Gumroad): unlocks the larger Whisper models, including Large-v3, and batch transcription, plus extras such as speaker labels. The Gumroad page lists the current set.
- Pros: Excellent interface, a big step up in features with Pro, works fully offline
- Cons: Not open source, Pro costs money, macOS only. The App Store edition ("Whisper Transcription") is a separate purchase, with Pro subscriptions from $6.99 or Pro Lifetime from $89.99 — check both before buying
Full breakdown in our MacWhisper pricing guide.
2. Buzz — the best free option#
Buzz is open source under the MIT licence, free, offline, and runs on Mac, Windows and Linux. It covers most of what people pay MacWhisper for.
- Pros: Free, no account, SRT/VTT export at no cost, a choice of engines (including whisper.cpp and faster-whisper), cross-platform
- Cons: Functional rather than attractive interface; long files take a while with large models. A separate paid build is sold on the Mac App Store, while the GitHub release is free
The honest comparison: if you need batch transcription and subtitle export without paying, Buzz covers both for free; MacWhisper's free version handles single files, and batch needs Pro. If you transcribe long recordings every week and care about a polished workflow, MacWhisper earns its price.

3. Whisper Desktop — the lightweight one (Windows)#
A simple, no-frills Whisper client by the developer Const-me. It's free, its source is on GitHub, and it's Windows only — it runs Whisper on your PC's graphics card.
- Pros: Lightweight, free, straightforward
- Cons: Windows only, fewer features, basic interface, and development has been quiet for a long time
On Windows it's a reasonable lightweight pick, though Buzz does more for the same price. On a Mac it simply isn't an option.
Which Should You Pick?#
On a Mac, free, and you want the most capable option: Buzz. Subtitle export and batch processing at no cost is a genuinely strong offer.
On a Mac, you transcribe regularly and want polish: MacWhisper Pro at €65. The interface and Pro features justify it if this is real work rather than an occasional task.
On Windows: Whisper Desktop if you want a lightweight GPU transcriber; Buzz if you want more features and subtitle export.
You want to try before deciding: MacWhisper's free version and Buzz are both free — install both, run the same file through each, and see which interface you prefer. Accuracy will be effectively identical at the same model size.
You want live dictation, not file transcription: none of these. They're built around loading audio and returning text, not typing at your cursor. VoiceInk and OpenSuperWhisper on Mac, or Handy on Mac, Windows and Linux, are built for that.
A Note on Privacy#
All three process locally, which is the strongest privacy position available — audio is never transmitted, so there's no retention policy to verify and no vendor to trust.
Two caveats worth knowing: if you switch on an optional feature that sends your transcript to an online AI service, that text does leave your computer, so leave such features off for confidential material. And verify locality yourself rather than trusting a description — turn Wi-Fi off and transcribe. If text still appears, it's genuinely local.
Our legal and medical privacy guide covers what to check before trusting any tool with confidential recordings.
Conclusion#
This comparison has a clearer answer than most: on a Mac, Buzz if you want free, MacWhisper if you'll pay €65 for polish. On Windows, Buzz or Whisper Desktop.
Whichever you pick, spend your effort on model selection rather than app selection. A well-chosen model on the "wrong" app beats a badly-chosen model on the "right" one every time.
Transcribing Files Is a Different Job From Writing#
These tools turn recordings into transcripts. If what you actually want is to write faster, that's a different category.
LumeVoice turns your speech into clean text in any app on Mac, Windows, iPhone or Android — filler words removed, self-corrections applied, no retyping. Unlike the three apps above it works in the cloud, so it needs a connection; audio isn't stored after processing and is never used for training. Start with 3,000 free words, no card required.
