Push-to-talk dictation for macOS.
Hold a key, speak, release — your words appear in whatever app you're typing in.

Vietnamese-first, English-friendly. Powered by Kyma API.

Most dictation tools treat Vietnamese as an afterthought. Haynoi is built for the way Vietnamese people actually speak — tiếng Việt with English mixed in mid-sentence ("deadline", "deploy", "team marketing") — and keeps both languages intact instead of translating or mangling one of them.

• Speaks your language(s). Vietnamese-optimized speech-to-text that handles Vi/En code-switching, with a custom dictionary for names and jargon the model should never get wrong.
• Works in every app. Text is inserted directly where your cursor is — editor, browser, chat, terminal — via the Accessibility API, with clipboard fallback.
• Nothing to configure. Sign in once with a Kyma account (free credit on signup). No API keys to paste, no model menus to study.

Hold ⌥  →  speak  →  release  →  text appears

That's the whole product. A floating bar shows the waveform while you talk; a layered chord confirms start/stop.

• Push-to-talk — hold the left ⌥ Option key (or ⌘ / ⌃ / fn), release to transcribe
• Language preference — auto-detect by default, or pin Tiếng Việt / English
• Your words are never lost — if the network fails mid-transcription, the recording is saved locally and retried with one click
• Survives real life — AirPods disconnecting mid-sentence, permission hiccups, and flaky Wi-Fi all degrade gracefully instead of eating your dictation
• Auto-paste into the active app, with clipboard fallback — and your previous clipboard is restored afterwards (dictated text is also hidden from clipboard managers)
• Living status orb — recording, transcribing, success, and error each have their own state, so you always know where your words are
• Custom dictionary — teach it names and terms once, it spells them right forever
• Snippets — say a trigger word, get expanded text
• Transcription history — searchable, stored locally, grouped by date
• Premium sound feedback — harmonic chords for start / stop / cancel / success
• Mute music — auto-pauses media while you dictate
• Silent auto-updates via Sparkle, launch at login, guided onboarding

Download the latest Haynoi.dmg from haynoi.com or GitHub Releases, drag it to Applications, and open it. The app is signed and notarized — no security warnings, and updates install themselves.

Prefer building from source?

git clone https://github.com/sonpiaz/haynoi.git
cd haynoi
brew install xcodegen    # if not installed
make run

First run, either way:

1. The onboarding wizard walks you through Microphone and Accessibility permissions — that's all Haynoi needs
2. Sign in with your Kyma account — free credit on signup, nothing to paste
3. Hold the left ⌥ Option key, say something, release — the guided first dictation shows you the loop

Haynoi defaults to the highest-accuracy tier and is transparent about what dictation costs:

_{*One push-to-talk utterance, billed per minute through Kyma. The free signup credit covers your first ~120 dictations.}

Switch tiers any time in Settings — it's one segmented control.

• Audio goes only to Kyma API for transcription, then is discarded — nothing is stored server-side beyond standard request logs
• Your Kyma credential lives in the macOS Keychain
• Transcription history stays on your Mac
• No analytics, no tracking, no telemetry in the app
