A Private Wispr Flow Alternative for Your Mac

Wispr Flow popularized a simple idea: hold a key, speak, and polished text is inserted wherever your cursor sits. It's a smooth experience. But for it to work, your voice is sent to the vendor's servers, which transcribe and rewrite it in the cloud. If you're dictating meeting notes, code, client messages, or anything sensitive, one question comes up fast: where exactly does my voice go, and who can access it?

If you're looking for a private Wispr Flow alternative, the question isn't just “does it transcribe well.” It's: who controls the pipeline, where does the processing happen, and what's still stored afterward.

The real problem: your voice goes to the cloud

Most AI dictation tools run as closed SaaS. You speak, the audio is sent to infrastructure you don't control, and the vendor's account becomes a mandatory middleman between you and the transcription model.

In practice, this creates three problems:

• You don't get to choose the AI provider or the processing region.
• You're dependent on a retention policy you have to take on faith.
• If there's a breach or a change in terms, your past recordings are out of your hands.

For many use cases, that's fine. For a lawyer, a doctor, a developer under NDA, or simply someone who doesn't want their voice passing through a third party — it isn't.

Speech Flow: same comfort, but with your own keys

Speech Flow is a native macOS dictation app (Apple Silicon, ~50 MB). The gesture is the same as what you already know: hold Ctrl, speak, release, and clean punctuated text is inserted at your cursor in any app — mail, code editor, Slack, Notion.

The difference is under the hood. Speech Flow is built on the BYOK (Bring Your Own Key) principle: you bring your own OpenAI, Gemini, or Groq API key. Transcription and rewriting go through your account, not through an intermediary. And no audio is stored by the app.

An LLM cleans up the result along the way: it strips filler words, adds correct punctuation, and adapts the tone to the active app. You dictate out loud and get text that's ready to use, no editing pass needed.

It also handles multiple languages — EN, FR, ES, IT — which is handy if you switch between English and other languages throughout the day.

Quick comparison

For a point-by-point breakdown, see the Speech Flow vs Wispr Flow page.

“BYOK” — what does it actually mean for my privacy?

This is the central point, so let's be precise and honest about it.

With BYOK, the app is no longer the middleman that sees your data pass through. Your voice is sent directly to the AI provider you chose, using a key that belongs to you. You're subject to that provider's terms (OpenAI's, for example), not to those of an additional app vendor layered on top. There's one fewer party between you and the model.

To be clear: BYOK doesn't mean “100% offline.” Transcription by a large model goes through your provider's API. What Speech Flow guarantees is that it adds no storage of its own and no intermediary server of its own — and that you keep control over the account that processes your voice.

What about the price?

Two plans, depending on whether you want to manage your own keys:

• €69 once, for life on BYOK: plug in your key and pay for AI at usage rates directly with the provider (usually a few cents a day for normal use).
• All-inclusive: €10/month or €70/year, keys provided, nothing to configure.

The first option is the most affordable and the most private over the long run. The second removes all setup if you'd rather not create an API account. Both are on the pricing page.

FAQ

Does Speech Flow work without a subscription?
Yes. The €69 license is a one-time lifetime purchase on BYOK. A subscription only exists if you prefer the all-inclusive plan with keys provided.

Are my voice recordings saved?
No. The app does not store audio. Your voice is sent to the AI provider you chose, and the text comes back to your cursor.

Does it work on an Intel Mac?
Speech Flow is designed for Apple Silicon (M1 and later). That's what keeps it lightweight and responsive.

In summary

If Wispr Flow's gesture won you over but the idea of sending your voice into a closed cloud gives you pause, Speech Flow offers the same comfort with a different model: your keys, your provider, no audio stored. It's a private Wispr Flow alternative built for people who want to keep their data on their own terms, without giving up speed.
