On-device & private
Transcription and cleanup both run on your Mac and iPhone. No servers, no streaming, no per-word fee. Your audio simply has nowhere else to go.
On-device dictation · powered by NVIDIA Parakeet
Talk.
It types.
On your device.
murmr is dictation that actually sounds like you wrote it — filler stripped, punctuation fixed, tone matched to the app. It all runs locally on your Mac and iPhone, so your voice never leaves your device.
Free to start · no account to talk · nothing uploaded, ever.

How it works
Three steps. Roughly four seconds.
There is no step four. That's kind of the whole pitch.
- 01
Hold fn — or tap the mic
On Mac, press and hold the fn / 🌐 key. On iPhone, tap the mic on the murmr keyboard. Double-tap fn if you'd rather go hands-free.
- 02
Talk like a human
Ramble. Backtrack. Say “um” a hundred times. murmr is listening on-device and isn't judging — that's the cleanup's job.
- 03
Clean text appears
Let go (or tap again) and polished, formatted text drops right where your cursor is. No copy-paste, no review step, no cloud round-trip.
See it work
Real product. Both pockets.
A custom keyboard on iPhone, a menu-bar app on the Mac. Same voice, same privacy, no cloud in sight.
iPhone keyboard
Talk into any text field
Switch to the murmr keyboard, hold to talk, and clean text lands right at your cursor — the filler stripped, the punctuation fixed, the tone matched to where you're typing. Tap “Tone: Auto” to override it anytime.
- Drops in everywhere a keyboard works
- Live, on-device waveform while you speak
- Swipe back to undo — nothing leaves the phone

Mac menu-bar app
Hold fn. Start talking.
murmr lives quietly in the menu bar. Press and hold the fn / 🌐 key from any app and a floating pill shows it's listening; let go and the cleaned text appears where your cursor was. Double-tap to go hands-free.
- Global hold-to-talk from any app
- A floating cue so you always know it's on
- Your last transcript stays on the device

Listening
The real app
Tap once. You're dictating.
No setup ritual. Open murmr, hit Start Dictation, and talk. This is the actual iPhone app — the same on-device engine that powers the keyboard, in a tap-to-talk surface for longer thoughts.
- One tap from open to dictating
- Runs fully offline — plane, tunnel, anywhere
- Authentic capture, not a mockup

Personalization
It learns the words you actually use
Teach murmr your teammates' names, product codenames, and the acronyms only your team says out loud. Set a default tone, and let it adapt per app from there. It all stays in your dictionary, on your device.
- A custom dictionary that nails the spelling
- Per-app tone, with a manual override
- Yours alone — never synced to a server

The good stuff
Dictation that pulls its weight
Not just speech-to-text. Speech-to-the-thing-you-actually-meant.
Kills filler, fixes punctuation
Every “um,” “uh,” and “you know” gets quietly deleted. Capitalization, commas, and sentence breaks land where they should — automatically.
Reads the room
Formal in Mail, punchy in Slack, tidy in Notes. murmr adapts the tone to whatever app you're typing into, so you don't have to.
Learns your jargon
Teammate names, product codenames, that one acronym only your team uses — add them once to your dictionary and murmr nails the spelling every time.
Works everywhere you type
Mail, Slack, Notion, the address bar, a random text field at 2am. If you can type into it, you can talk into it.
Mac + iPhone
A menu-bar app for the Mac and a custom dictation keyboard for iPhone. One voice, both pockets, zero cloud.
The whole point
Your voice never leaves your device. Full stop.
Most “AI” dictation apps stream your microphone — and sometimes whoever you're on a call with — to a rented GPU in someone else's data center. That round-trip is their entire business model.
murmr deletes the round-trip. Speech recognition runs on the Apple Neural Engine; cleanup runs on Apple's on-device models. There's no server to send audio to, because there's no server.
- No audio or transcripts uploaded — ever
- Works on a plane, in a tunnel, fully offline
- Your custom dictionary stays yours
- $0 marginal cost, because there's no cloud to pay for
Typical cloud dictation
your mic→the internet→someone's GPU→back to you
Your voice takes a field trip. You pay per word.
murmr
your mic→your device→your text
Nothing leaves. Nothing to bill. Nothing to leak.
