Search for "the Whisper app" and you'll find a confusing mix of results. Here's the honest answer: Whisper is a model, not an app — and once you understand that, getting great local transcription and dictation on a Mac is straightforward.
What Whisper actually is
Whisper is an open-source automatic speech recognition (ASR) model released by OpenAI. It converts spoken audio into text with remarkable accuracy across dozens of languages. What it isn't is a downloadable consumer app with buttons and a window. There's no official "Whisper.app" in the Mac App Store from OpenAI. To actually use it, you run it through something.
Three ways to run Whisper on a Mac
1. The command line (whisper.cpp)
whisper.cpp is a fast C/C++ port that runs Whisper efficiently on Apple Silicon. It's free and powerful, but it's a terminal tool — you download a model file, point it at audio, and read the output. Great for tinkerers. We dig into why it's so fast in Whisper.cpp on Apple Silicon.
2. A file-transcription app
If you mainly need to turn recordings into text, a GUI app that bundles Whisper — like MacWhisper — gives you drag-and-drop transcription and subtitle export without touching the terminal. See our MacWhisper alternatives roundup for options.
3. A dictation app
If you want to talk into apps rather than transcribe files, Sotto runs Whisper (and NVIDIA Parakeet) models locally and types your words into whatever app has focus when you press a hotkey. It handles punctuation, custom vocabulary, and cleanup automatically, and keeps every recording so you can re-transcribe with a better model later. One-time $49, no subscription.
Which Whisper model size should you use?
Whisper comes in several sizes — tiny, base, small, medium, large — trading speed for accuracy. On a modern Mac, medium and large run comfortably on the Neural Engine. We break down the trade-offs in Whisper large vs medium vs small.
Why local Whisper beats cloud transcription
- Privacy: your audio never leaves the Mac.
- No per-minute fees: transcribe as much as you want.
- Works offline: on a plane, no problem.
- No shutdown risk: a local model can't be deprecated out from under you.

Bottom line
"The Whisper app" is really just a friendly wrapper around an open model. Pick the wrapper that matches your goal: the terminal for hacking, a file app for transcription, or a dictation app like Sotto for talking into any app on your Mac — all running locally, no cloud required.
