What makes it different

Built for the way you actually work.

Every detail tuned so dictation feels like a keyboard shortcut, not a tool you have to switch into.

One key. Three behaviors.

Hold for push-to-talk. Quick-tap to lock-on, tap again to stop. The mode you want is the gesture you used. Smart, hold, or toggle — your call.

Capture any key.

Even unnamed media keys. Murmur falls back to scan codes so the Copilot key, your mouse thumb button, or that weird F23 all work.

Your keys. Your data.

Audio goes from your mic to the provider you picked, with the API key you own. Nothing in between.

Pro · v1.1 Catches what the model missed.

A second-pass review reads your transcript like a careful editor — fixing homophones, restoring dropped negations, and rescuing garbled names. Voice and structure stay yours. Set it to never, sometimes, or always.

You see it listening.

A real level meter. Not a fake animation. So you know the mic heard you before you walked away.

Recents that respect you.

Scrolling history, kept locally. Never synced. Clear it with one click and it's gone — no soft-delete, no recoverable trash.

Quiet by default.

Lives in the system tray. No popups, no permissions popping over your work. Open the window only when you want to.

How it works

Three steps. One key.

  1. 01

    Pick a key — any key.

    Open Settings → Hotkeys → Capture, then press what you want. Murmur learns its name and its scan code, so even keys Windows doesn't formally know still bind.

  2. 02

    Hold it. Speak.

    Audio streams to your provider the moment you press. Release and it stops — there's no minimum recording length, no awkward silence detector.

    Live
  3. 03

    Your words appear.

    Wherever your cursor is. Email, terminal, IDE, browser, Discord — it's just typed text. No window switch, no paste step.

The app

A window worth opening.

State orb, real audio meter, segmented mode picker, recents, tray. Quiet when you don't need it; obvious when you do.

Early users

Quiet praise.

I bound it to my mouse thumb button on day one. A week later I noticed I was writing commit messages without lifting my hands off the keyboard. That's the whole pitch.

I write essays for a living. I tried Wispr on my work Mac and Murmur on my Windows machine. Murmur is calmer — it doesn't keep nudging me. The history pane is enough.

The Smart mode is the right default. Tap to toggle for long thoughts, hold for quick replies. I haven't touched the settings since the second day, which is the highest compliment I give software.

Why not Wispr Flow?

Different priorities.

Wispr Flow is great. It's also Mac-only, closed-source, and rents you the model you're already paying for.

FAQ

Quick answers.

Do I need a paid API key?
Groq's free tier is enough for light daily use. Gemini also has a generous free tier. You'll only need to pay if you dictate hundreds of times a day.
Where does my audio go?
Straight from your mic to whichever provider you set up. Murmur has no server. Audio is streamed, not stored.
Will it intercept the Copilot key?
Yes — but Windows tries first. Disable the stock launcher in Settings → Personalization → Text input, or remap with PowerToys, and Murmur takes over cleanly.
Does it work on ARM64?
Groq path: yes, fully. Gemini path needs grpcio, which doesn't ship ARM64 wheels for Python 3.13 yet. So Groq is the default working path on ARM.
Why isn't it just a tray icon?
It is. The window is optional — close it any time and Murmur keeps running silently. start.bat launches without a console; the tray icon is the persistent presence.
Is there a Mac or Linux build?
Not yet. Murmur is built around Windows-specific keyboard hooks. A Mac build is on the roadmap but not promised.
Will the accuracy review send my audio anywhere new?
No. The review never sees your audio. It sends only the transcribed text to the chat model of the provider you've already configured — same Groq or Gemini key, same endpoint as your transcription. No new vendor, no new traffic destination.
Can I turn the AI features off entirely?
Yes. Set Accuracy review to never and Format mode to verbatim, and Murmur will type back exactly what the speech model returned — no second pass, no smart formatting, no rewrites.
