Press ⌥⌘D
One global hotkey, in every app on your Mac. Wherever the cursor blinks, Harf listens.
Out Loud
You speak at 150 words a minute. You type at 40. This is a day spent keeping the difference.

(01) — First words
The first thought of the day never waits for a keyboard.
It arrives in the shower, on the stairs, halfway through a kettle. By the time a document is open, it has already started to fade. So don’t type it — say it. Press ⌥⌘D, and wherever your cursor blinks, Harf is listening. Stop talking, and the thought is text.
150 words a minute, spoken vs 40 typed. Harf returns the difference.
This is what a thought looks like at 06:58 — air, pressure, breath. Harf’s only job is to freeze it before it melts.

Dictation N°1 — recorded 09:12
“Reply. Send. Next.”
(02) — The inbox
Nine a.m. is a wall of replies. Talk it down.
Dictate each answer and let a prompt do the polish before the text lands. Clean Up strips the ums. Formal straightens the tie. Email adds the greeting and the sign-off. Or write your own prompt — your voice arrives already edited.

(03) No step three
Speak. It’s written.
The whole revolution is that there is no step three.
Say it
Any of fifty languages, at a natural pace. A floating chip row rides along if you want to switch.
Stop
A short pause, and your words are typed at the cursor. No paste. No app switch. No step three.

Two o’clock is when the real writing happens.
If nothing interrupts. Harf lives in the menu bar and never asks for a window. Switch language mid-sentence, fire a prompt, press Esc to cancel, or ⌥⌘D to finish instantly. The interface disappears. The words don’t.

(05) Tongues
(05) — Tongues
The four-thirty call is in two languages and your notes are in a third. Harf holds fifty — and switches between them mid-sentence, mid-recording, mid-thought, from a floating chip row. Total keystrokes required: one.
Fifty tongues. One key.
English by Parakeet, forty-nine more by Whisper large-v3 — the best on-device model per language, chosen automatically.

The evening call has four voices. Keep them all.
Hit record in any meeting — on a call or across a table. Harf transcribes live, timestamps every line, and saves the whole thing as a plain text file on your disk. Searchable, quotable, deletable. Nothing is uploaded, because there is nowhere to upload to.
