# Hold a key. Speak. Done.

Haynoi is push-to-talk dictation for macOS. Hold ⌥, say what you mean, release — and polished text appears in any Mac app: email, chat, code editors, anywhere. **Sub-2-second** transcription with Vietnamese-first accuracy and an orb that disappears when you're finished.

The whole loop

## Three moments. That's the entire app.

Speaking is about three times faster than typing — Haynoi closes that gap for every app on your Mac, from silence to finished sentence without interrupting your flow.

01 · Hold

### Hold the key

Press and hold ⌥ (or any key you choose) anywhere on your Mac. The orb floats up quietly — it's listening.

02 · Speak

### Speak naturally

Talk as you think — full sentences, mixed Vietnamese and English, technical terms. Every word captured, no drift in accuracy.

03 · Done

### Text appears

Release the key. Within two seconds, polished text lands exactly where your cursor was — the email, Slack thread, or code comment you had open.

⌥

What it does

## Built for people whose words move fast.

Haynoi is small by design. Every feature earns its place.

### Vietnamese-first accuracy

Tuned for how Vietnamese speakers actually talk — tones, regional accents, and the natural code-switching between Vietnamese and English that defines how most of us communicate at work.

### Works in every Mac app

Email, Slack, Notion, VS Code, Terminal, even the address bar — Haynoi injects text at the cursor level, so it works anywhere a keyboard would. No special integration required.

### Fast and Quality tiers

Choose Fast for speed-first dictation where you edit after, or Quality when the first draft needs to be publication-ready. Switch per session — both on the same push-to-talk shortcut.

### Smart output modes

Clean mode strips filler words. Email mode shapes a proper greeting and sign-off. Auto reads context and picks for you. Speak naturally; Haynoi decides how it should read.

### Custom dictionary and snippets

Teach Haynoi your project names, company terms, and abbreviations once. From then on they transcribe correctly — no more "Affitor" becoming "a filter" or "Kyma" becoming "karma."

### Silent auto-updates

Haynoi updates itself in the background via Sparkle. You open the app you love, never a maintenance window you didn't ask for. New transcription models land without lifting a finger.

The name carries a meaning

hãy nói

Speak up — the command

hay nói

Loves to talk — the person

Hà Nội

The city — an Easter egg

A name that works three ways at once felt right for a tool built around voice. *Hãy nói* is the imperative — the first thing you say to a microphone, and the quiet instruction the app gives you every time you hold the key.

*Hay nói* is the personality. The kind of person who has always thought faster than they could type, whose best ideas arrive in speech and evaporate before fingers catch up. Haynoi exists for that person.

And then there is Hà Nội — the city that the founder still hears in his vowels, left as a quiet wink for anyone who notices. Three layers, one word, zero explanation needed.

S

Built by **Son Piaz** — a Vietnamese founder who has spent enough late nights typing what he should have just said out loud.

Questions

## Straight answers.

**What is Haynoi?**
Push-to-talk dictation for macOS. Hold a key (the left Option key by default, or ⌘/⌃/fn), speak, release, and the text is typed into whatever app you are in: email, chat, code editors, terminals.

**Which Macs does it run on?**
macOS 14 or later, on Apple silicon and Intel.

**How much does it cost?**
Free for 5,000 words a week, resetting every Monday. Haynoi Pro with unlimited words is coming soon.

**Does it understand Vietnamese and English together?**
Yes. It is built for Vietnamese with English words mixed in mid-sentence, and you can also pin it to Vietnamese or English only.

**Is my voice stored?**
No. Audio is sent for transcription and then discarded; it is never stored on the server. Your dictionary and dictation history stay on your Mac.

**Does it need an internet connection?**
Yes, transcription runs in the cloud. If the network drops mid-dictation, the recording is kept on your Mac so you can retry it.
