The product
One key. Your voice. Finished writing.
Murmur AI is a small Mac app that sits in your menu bar. Hold a key, say what you mean, let go — and the finished version types itself wherever you were already working.

Press play on a spoken thought and watch the shape it arrives in. This is the same rewriting the app does on your Mac.
You say
One keypress, three shapes. Pick where it's going and Murmur writes to fit.
Murmur writes
What it actually is
A better keyboard, not another app to visit
Dictation software gives you a transcript: every “um”, every doubling back, no punctuation, and a tidy-up job that takes as long as typing would have. Murmur AI does the tidy-up. It listens to a whole thought, works out what you were driving at, and writes it properly.
There is nowhere to log in and nothing to check. You keep working in the app you were already in — the only difference is that your hands stop doing the writing.
Five shapes
Same voice, different finish
Pick a shape before you speak, or let Murmur AI read the app you're in and choose for you.
Greeting, the point up front, a clear ask, sign-off. Your phrasing, tidied — not a template.
Message
Two lines, no preamble. For Slack, WhatsApp and the reply you keep putting off.
Notes
Headings and bullets pulled out of a rambling five minutes of thinking aloud.
List
Every action you mentioned, one per line, in the order you said them.
Verbatim
Exactly what you said, punctuated. For quotes, interviews and dictation you'll edit yourself.
Features
Everything in the £39
Hold a key, anywhere
Fn by default, or any key you like. Mail, Slack, Notes, Pages, your terminal, a text field on a website — Murmur AI types where the cursor already sits, so nothing needs copying across.
Speech never leaves your Mac
Recognition runs on Apple Silicon. No audio is uploaded, no transcript is stored on a server, and it keeps working on a plane with the wifi off.
Finished writing, not a transcript
Filler, false starts and “actually, scratch that” are cleaned up. You get the sentence you meant, not the one you stumbled through.
It learns your words
Add client names, product names, medical or legal terms to your dictionary once and they land spelled right every time.
Punctuation you don't dictate
Commas, full stops and paragraph breaks are inferred from how you speak. Say “new paragraph” if you'd rather be explicit.
Quiet by design
No dashboard, no streak counter, no notifications. A small menu-bar mark that pulses while you talk, and nothing else.
