Voice-to-text AI for every app

Don’t type. बोलो

You speak three times faster than you type. Hold one key, talk naturally, and finished sentences land in any app on your Mac, in any of 50 languages. Your voice never touches the internet.

you say “umm so yeah, push the launch to Friday? because, uh, QA isn’t done…”

harf hears what you meant “~~umm so yeah,~~ push the launch to Friday? because~~, uh,~~ QA isn’t done…”

harf types “Push the launch to Friday. QA isn’t done.” No umms. No typos. Nothing to fix after.

The same key, every language

Your day isn’t monolingual. WhatsApp your mother in Hindi, reply to a client in English, take notes in தமிழ். Harf follows, without being told twice.

I’ll send the notes tonight.

How it works

Put your cursor anywhere

Notes, Mail, WhatsApp, VS Code, a browser. If you can type there, Harf can write there. No separate app to paste out of.

Hold the globe key and talk

Every time you pause for breath, that sentence lands at your cursor in one clean pass. Hands busy? Tap ⌥⌘D and go.

Let go. It’s written.

Punctuated, capitalised, fillers gone. In whichever of the 50 languages you were thinking in. The mic shuts itself off after a quiet spell, so you can just stop talking and walk away.

Every app on your Mac

One voice. Every app.

There is no Harf window to paste out of. Speak wherever your cursor is, and Harf matches the room: casual in chat, proper in mail, tidy in code. Same thought, said once.

Private by design

Turn off the Wi‑Fi. Keep talking.

Cloud dictation ships your voice to a data center and asks you to trust what happens next. Harf never makes the trip. The entire speech model lives on your Mac’s chip, so your voice becomes text without touching a network.

network: connected

Go on, flip it. The typing won’t even stutter.

What leaves your MacNothing

What we can seeNothing

What works offlineEverything

Someone dancing through a sunlit meadow with a phone to their ear — dictating, offline.

Beyond dictation

Say less. Mean more.

Turning speech into text is just the start. Harf also remembers what you repeat, edits the moment you ask, and matches your tone to the reader — all on your Mac.

Voice commands

Edit without touching the keyboard.

Say what you want to change — “new line”, “make it a list”, “delete that”. Harf does it while you keep talking.

Snippets

Say the cue. Get the whole thing.

Save the things you type over and over. Say a short cue, and Harf writes out the whole thing.

Tone

Same words, any tone.

Casual for a teammate, formal for a client — you pick, and Harf rewrites it to match.

Vocabulary

Spells Nietzsche right. Every time.

The words you say most are the words no dictionary knows: your cofounder’s surname, your hometown, the product you named yourself. Correct Harf once, and it never gets them wrong again, in any of the 50 languages. Your words stay on your Mac, not in somebody’s training data.

Meetings

The whole call, on paper.

Zoom, Meet, Teams, anything through your speakers, plus your own mic. Speakers are told apart and named when they introduce themselves. One tidy file lands in your folder. No bot joins. No audio leaves.

The makers

Two people who hated typing.

Harf isn’t a startup with a growth team or a pitch deck. It’s a two‑person project — built by hand, obsessed over pixel by pixel and millisecond by millisecond, and shipped only once it felt effortless. If a keystroke can be saved, we’ve probably argued about it.

Neil Sarjal

Engineering

Makes the speech model quick enough to feel instant and private enough to stay on your Mac. Chases the milliseconds most people never notice — because that’s exactly why it feels effortless.

Design & product

Shapes how Harf looks, feels, and gets out of your way — sweating the space between two letters until it’s right. Believes the best interface is the one you forget is there.
