Does my audio ever leave my Mac?

No. Transcription runs entirely on your Mac and works offline. Audio is never uploaded, and the recording is deleted after each transcription. The only time any text leaves your machine is if you explicitly choose the optional OpenAI provider for AI cleanup.

How much does OpenWhisp cost?

Nothing. OpenWhisp is free and open source under the MIT license — no account, no subscription, no usage meter.

What are the system requirements?

An Apple Silicon Mac (M1 or newer) running macOS 14 Sonoma or later.

How is it different from the built-in macOS dictation?

OpenWhisp streams words in about 0.3 seconds behind your voice, already punctuated, and adds things macOS dictation doesn't have: voice editing of selected text, AI refinement that runs offline, custom vocabulary, per-app modes, a searchable local history, and a built-in MCP server so AI coding agents can use your voice.

Can AI coding agents like Claude Code use OpenWhisp?

Yes. OpenWhisp doubles as a local MCP server, so Claude Code, Cursor, and any MCP-aware agent can ask you questions out loud and take your spoken answer, rewrite text with your on-device model, and read your recent dictations. It works with any API key or Bedrock setup, over SSH, and in regulated environments, because nothing is ever sent to the cloud. It is off until you enable it, and you approve each agent and each capability.

How do I install OpenWhisp?

Download the DMG, drag OpenWhisp to your Applications folder, and open it. The build is signed and notarized by Apple, so it launches with a double-click — no Gatekeeper prompts. You can also build it yourself from source.

Is there a free alternative to Wispr Flow?

Yes. OpenWhisp is a free, open-source Mac dictation app that does hold-to-talk dictation into any app, runs entirely on-device, and has no subscription.

Does OpenWhisp work offline like a local alternative?

Yes. Transcription runs on-device with WhisperKit on Apple's Neural Engine (whisper.cpp is available as a fallback), so OpenWhisp works with no internet connection and your audio never leaves your Mac.

What's the catch with a free Wispr Flow alternative?

OpenWhisp is Mac and Apple-Silicon only, so there's no Windows, iPhone, or Android version. It also has fewer cross-platform and sync features than a paid cloud app like Wispr Flow.

OpenWhisp: a free, local Wispr Flow alternative for Mac

The best free Wispr Flow alternative for Mac is OpenWhisp: it does the same hold-to-talk dictation into any app, but runs 100% on-device, costs nothing, and is open source. Where Wispr Flow is cloud-based and $15/month, OpenWhisp keeps your audio on your Mac and never charges a subscription.

Wispr Flow popularized fast, modern dictation on the Mac — hold a key, talk, and clean text appears in whatever app you’re in. The friction points people hit are its price ($15/month), its cloud-first design (your speech is processed on their servers), and a free tier capped at 2,000 words a week. If any of those bother you, here’s the honest comparison.

OpenWhisp vs Wispr Flow at a glance

Price: OpenWhisp is free and open source (MIT). Wispr Flow is $15/month.
Where it runs: OpenWhisp transcribes on-device with WhisperKit on Apple’s Neural Engine; Wispr Flow is cloud-based.
Privacy: With OpenWhisp your audio never leaves the Mac (unless you opt into a cloud model). Wispr Flow sends audio to its servers.
Platforms: Wispr Flow is cross-platform. OpenWhisp is Mac and Apple Silicon only.
Extras: OpenWhisp adds voice editing of selected text, offline AI cleanup, custom vocabulary, and per-app modes.

Where Wispr Flow is still the better pick

To keep this fair: if you work across Windows, iPhone, and Mac and want one polished tool that syncs everywhere, Wispr Flow’s cross-platform coverage and cloud accuracy are genuinely strong. OpenWhisp is Mac-only by design — that’s the trade for running entirely on your own hardware.

Where OpenWhisp wins

If you’re on a Mac and you care about privacy or hate subscriptions, OpenWhisp is the clearer choice. Transcription runs locally, so it works offline and nothing is uploaded. It’s free forever because the compute is your own machine. And because it’s open source, you can read exactly what it does — or change it. It also goes a step beyond dictation: you can select text in any app and edit it by voice, and run an AI cleanup pass on a small model that lives on your own disk.

Getting started

OpenWhisp needs an Apple Silicon Mac on macOS 14 or later. Download it from the OpenWhisp site or grab the source on GitHub. The download is signed and notarized by Apple, so it opens with a double-click.
