What's new in VocalFlow
- 01
Redesigned Settings
A brand-new sidebar layout with color-coded sections — Dictation, Transcription, AI Polish, Corrections, Dictionary, Permissions & About.
- 02
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.
- 03
Learns Your Corrections
Type over a word you just dictated and VocalFlow auto-learns the corrected spelling — next dictation gets it right.
- 04
AI Polish
Optional spelling & grammar fixes, code-mix transliteration and translation via Groq or OpenRouter — plus your own custom instructions.
- 05
Auto-Updates
The Mac app updates via Sparkle and the Windows app updates itself from GitHub releases — you are always on the latest build.

Run the .pkg installer, or drag VocalFlow.app into your /Applications folder.
- 03

If you used the .zip, macOS may quarantine it. Run this once in Terminal:
xattr -dr com.apple.quarantine /Applications/VocalFlow.app - 04

Click the menu bar icon → Settings → paste your Deepgram API key. You're done.
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
- 01
Configurable Hotkeys
Choose Right Option / Command on Mac, or Right Alt / Ctrl on Windows. Set it once and forget it.
- 02
Real-time ASR
Audio streams directly to Deepgram's WebSocket API for ultra-low-latency transcription.
- 03
AI Post-Processing
Groq LLM optionally corrects grammar, transliterates code-mixed speech, or translates across languages.
- 04
Universal Compatibility
Works in every app on macOS and Windows — Notion, VS Code, Slack, browsers, terminals. Any text field.
- 05
Menu Bar / Tray App
Lives quietly in your macOS menu bar or Windows system tray. Zero UI friction, always ready.
- 06
Secure Key Storage
API keys are encrypted at rest — macOS Keychain on Mac, Windows DPAPI on Windows. Never in plain text.
- 07
Personal Dictionary
Lock exact spellings of names & jargon, and expand spoken triggers into longer text. Entries bias recognition itself, not just the output.
- 08
Learns Your Corrections
Correct a dictated word by typing over it and VocalFlow remembers your spelling for every dictation after.
- 09
Auto-Updates
Sparkle-powered updates on macOS and GitHub-release self-updates on Windows keep you on the newest build.
