Think out loud. Keep every thread.
Nothing leaves your Mac.
Some thoughts only arrive when you're talking, not typing. Mutter lets you riff, the whole tangent, and turns it into clean writing you can shape. On your Mac, private, and it never drops the thread.

Built for how you actually work
Ideas arrive faster than you can type, and the act of typing kills the very flow of thinking you're trying to capture.
Made for riffing
Talk the whole messy tangent. Mutter keeps the thread and turns it into clean prose you can refine, thinking first, editing later.
Never lose an idea
The thought is captured the instant you stop, before it pastes, and kept in a searchable history you can mine later.
Half-formed thoughts stay yours
Private mode transcribes on your Mac. Your unfinished ideas are never uploaded to anyone's server.
A record of your thinking
Every session is saved to a local, searchable history, your second brain of everything you've thought aloud.
A riff becomes an essay
Intent mode notices what you're making, an essay, a post, a note, and turns the tangent into a structured first draft you can refine.

Your voice never leaves your Mac.
Private mode keeps every half-formed thought on your Mac, nothing is uploaded, ever. And every word is written to a searchable history the moment you finish, before it even pastes, so you never lose a thought.
Questions deep thinkers ask
Is it okay if I think messily?
That's the point. Riff freely, Mutter keeps the thread and cleans up the filler so you can shape it afterward.
Is my writing private?
In Private mode, everything is transcribed on your Mac and nothing is uploaded.
Can I search what I've thought about before?
Yes. Every dictation is saved to a local, searchable history you can revisit anytime.
Does it clean up filler words?
Yes, the 'ums', false starts, and repeats are smoothed into readable prose while keeping your meaning.
