What's new in VocalFlow

The latest releases bring a redesigned Settings experience, a personal Dictionary, and smarter corrections to macOS & Windows.

Redesigned Settings

A brand-new sidebar layout with color-coded sections — Dictation, Transcription, AI Polish, Corrections, Dictionary, Permissions & About.

Personal Dictionary

Lock the exact spelling of names & jargon, or expand a spoken trigger into longer text — say "my email" and the full address is typed. Star favorites to pin them.

Learns Your Corrections

Type over a word you just dictated and VocalFlow auto-learns the corrected spelling — next dictation gets it right.

AI Polish

Optional spelling & grammar fixes, code-mix transliteration and translation via Groq or OpenRouter — plus your own custom instructions.

Auto-Updates

The Mac app updates via Sparkle and the Windows app updates itself from GitHub releases — you are always on the latest build.

Get Started

Up and running in minutes

Free download. No account, no subscription, no credit card. Just install and speak.

2

Install the app

Run the .pkg installer, or drag VocalFlow.app into your /Applications folder.

3

If you used the .zip, macOS may quarantine it. Run this once in Terminal:

4

Grant permissions

Open VocalFlow and allow Microphone and Accessibility access in System Settings when prompted.

5

Add your API key

Click the menu bar icon → Settings → paste your Deepgram API key. You're done.

Latest: v2.5.0 (macOS) · v1.3.0 (Windows)

How It Works

Three steps to voice nirvana

01
Hold your hotkey

Press and hold your configured global hotkey — Right Option / Command on Mac, Right Alt / Ctrl on Windows. VocalFlow listens anywhere, in any app.

02
Speak naturally

Your voice streams in real-time to Deepgram's WebSocket API. Transcription happens as you talk.

03
Text appears instantly

Release the key. Groq optionally polishes the transcript, then the text is pasted at your cursor (Cmd+V on Mac, Ctrl+V on Windows).

Features

Everything you need, nothing you don't

Configurable Hotkeys

Choose Right Option / Command on Mac, or Right Alt / Ctrl on Windows. Set it once and forget it.

Real-time ASR

Audio streams directly to Deepgram's WebSocket API for ultra-low-latency transcription.

AI Post-Processing

Groq LLM optionally corrects grammar, transliterates code-mixed speech, or translates across languages.

Universal Compatibility

Works in every app on macOS and Windows — Notion, VS Code, Slack, browsers, terminals. Any text field.

Menu Bar / Tray App

Lives quietly in your macOS menu bar or Windows system tray. Zero UI friction, always ready.

Secure Key Storage

API keys are encrypted at rest — macOS Keychain on Mac, Windows DPAPI on Windows. Never in plain text.

Personal Dictionary

Lock exact spellings of names & jargon, and expand spoken triggers into longer text. Entries bias recognition itself, not just the output.

Learns Your Corrections

Correct a dictated word by typing over it and VocalFlow remembers your spelling for every dictation after.

Auto-Updates

Sparkle-powered updates on macOS and GitHub-release self-updates on Windows keep you on the newest build.
