Murmur

Speak.
It types itself.

Murmur is a native macOS dictation app that lives in your menubar. Hold a key, say what you mean, let go. Your words appear wherever your cursor is -- cleaned up, punctuated, and private. Everything stays on your Mac.

Free · macOS 14+ · Apple Silicon

Every step runs locally. No internet required. No data leaves your Mac.

Two dictation modes

Fnhold

Push to Talk

Hold your key to record. Release to transcribe and paste. Fast, surgical. Ideal for short bursts mid-typing.

⌥ Spacetoggle

Hands-Free

Press once to start recording, again to stop. Walk around, think out loud, dictate long-form without holding anything.

Built for how you actually talk

100% local

Whisper runs on your Mac. Audio never touches a server. No account, no subscription, no telemetry.

Auto-learn dictionary

Murmur watches your edits. If you correct a word after dictation, it learns the fix for next time.

Verbal corrections

Say "change tomorrow to Thursday" within 60 seconds and Murmur rewrites the text in place. The correction saves to your dictionary.

Spoken punctuation

Say "exclamation point" and get !. Say "new paragraph" and get a line break. Natural punctuation without touching keys.

Filler removal

Ums, uhs, and likes are stripped automatically. What lands in your document is what you meant to say.

iCloud sync

Your custom dictionary syncs across every Mac via iCloud. Add a word on your laptop, it appears on your desktop.

LLM cleanup

Optional local LLM pass via Ollama cleans up self-corrections and adds obvious punctuation. 2-second timeout, silent fallback.

Launch at login

Set it and forget it. Murmur starts with your Mac and waits quietly in the menubar until you need it.

No cloud. No account. No tracking.

Murmur uses Apple's Whisper engine running directly on your Mac's neural engine. Audio is recorded, transcribed, and discarded -- all in a fraction of a second. When iCloud sync is enabled, only your dictionary word pairs travel through iCloud. Audio never does.
