Your dictionary
It learns your world, once
Names, clients, jargon. Add them once and they're spelled right forever after.

Talk it through. It arrives written.
Speak the way you actually think — sideways, self-correcting, half-finished. Murmur AI hands back a sendable email, a two-line message or tidy notes, right where your cursor sits.

The difference
Dictation types what you said. Murmur AI writes what you meant.
Anyone can turn talk into text. The work is in the shape — a rambling thought becoming a clear email, a short message, a tidy list. That happens before a single character lands.
Ordinary dictation
um so tell sam the deadline's moving to thursday no wait friday and can someone chase the contractor about the snagging list
Murmur AI, email
A quick change of plan: the deadline is moving to Friday rather than Thursday. Before we sign anything off, could someone chase the contractor about the snagging list?
Small things, done properly.
Three of the details you'd only build if you used this every hour of the day.
Your language
Your spelling, your idiom
British English if you're British, and dozens of languages besides — each with its own conventions.

Private by design
Your voice never leaves
Recognition and rewriting both run on your Mac. Nothing uploaded, so there's nothing to leak.

People who stopped typing.
“I talk for ten seconds and a proper email comes out. I haven't written a first draft in months.”
“The dictionary was the moment it clicked. It spells every client name right, first time.”
“I dictate patient notes. Nothing leaving the machine wasn't a nice-to-have, it was the whole decision.”
