Open System Settings
Click the Apple menu () in the top-left corner and select System Settings. Navigate to Keyboard.
Enable Dictation
Scroll down to the Dictation section and toggle it on. Choose your language and whether to use Enhanced Dictation (on-device) or standard (cloud).
Start Dictating
Place your cursor in any text field and press the Fn key twice (or the microphone key on newer MacBooks). A small microphone icon appears — start talking.
Use Voice Commands
Say "period", "comma", "new line", "new paragraph" for punctuation. Say "caps on/off" for capitalization.

Download & Install
Go to metawhisp.com/download and download the app. Drag it to Applications. Takes about 30 seconds.
Grant Permissions
On first launch, MetaWhisp will ask for Microphone and Accessibility permissions. Both are required — Microphone to hear you, Accessibility to paste text into apps.
Press Right Option (⌥) and Speak
That's it. Press Right Option from anywhere on your Mac. A floating indicator appears. Speak naturally. Press Right Option again to stop. Your text appears wherever your cursor is.
Choose Your Processing Mode
Open MetaWhisp settings and choose how your text gets processed:
| Mode | What it does | Best for | Needs API key? |
|---|---|---|---|
| Raw | Verbatim transcription — exactly what you said | Journaling, brainstorming, taking notes | No (free) |
| Correct | Removes "um", "uh", fixes grammar, adds punctuation | Emails, Slack messages, documentation | Yes (OpenAI) |
| Rewrite | Transforms casual speech into polished professional text | Business emails, reports, client communication | Yes (OpenAI) |
| Translate | Speak in one language, get text in another | Multilingual teams, writing in a non-native language | Yes (OpenAI) |
Pro tip
Raw mode is completely free — it runs 100% on your Mac with no API key needed. Correct, Rewrite, and Translate modes use your own OpenAI API key, which costs pennies per day for typical usage (literally $0.01-0.05/day).
The Voice-First Workflow
Step 1: Dictate your thoughts in Raw or Correct mode (2 minutes)
Step 2: Quick review and light editing (1 minute)
Step 3: Send/publish
Total: 3 minutes vs. 10+ minutes of typing the same content.
| Task | Best mode | Why |
|---|---|---|
| Slack messages | Correct | Clean but still sounds like you |
| Client emails | Rewrite | Professional tone automatically |
| Code comments | Raw | Preserve technical terms exactly |
| Meeting notes | Correct | Remove filler words, keep structure |
| Blog drafts | Raw | Capture ideas, edit later |
| Multilingual comms | Translate | Speak in native language, send in English |
| Method | Time | Errors | Edit time | Total |
|---|---|---|---|---|
| Keyboard typing | 4 min 20 sec | 3 typos | 30 sec | 4 min 50 sec |
| macOS Dictation | 1 min 40 sec | 8 errors | 2 min | 3 min 40 sec |
| MetaWhisp (Raw) | 1 min 20 sec | 2 errors | 30 sec | 1 min 50 sec |
| MetaWhisp (Rewrite) | 1 min 20 sec | 0 errors | 10 sec review | 1 min 30 sec |
Result
MetaWhisp Rewrite mode produced a 200-word email in 1 minute 30 seconds — 3x faster than typing. And the output was more polished than what we'd have typed manually.
"Dictation keeps stopping after a few seconds"
macOS Dictation has a timeout. Switch to MetaWhisp which has no time limit — speak for as long as you want in toggle mode.
"It doesn't understand technical terms"
macOS Dictation has no vocabulary system. MetaWhisp's auto-learning feature lets you correct terms once, and it remembers them forever.
"Voice typing doesn't work in my app"
macOS Dictation doesn't work in some Electron/web apps. MetaWhisp uses system-level accessibility to paste text into any app — Terminal, VS Code, Figma, literally anything.
"I'm worried about privacy"
macOS Enhanced Dictation sends audio to Apple. MetaWhisp processes everything on-device — your voice data never touches a server. It works perfectly in airplane mode.
