Your voice,already written.

Private, context-aware dictation that runs on your Mac. SpeechAnalyzer transcribes while you speak; on-device intelligence makes the result feel finished.

Ask without leaving the cursor.

Begin a normal dictation with “Hey Megaphone.” The on-device Foundation Model answers inside the app you are already using—no separate chat and no copy-paste loop.

The app, as it actually works.

One native settings system for vocabulary, cleanup, and context. The controls below mirror Megaphone’s macOS interface instead of inventing a second product for the website.

Dictionary
▤ Your Dictionary

Teach Megaphone the names, products, acronyms, and technical terms that make your writing yours. Dictionary words give transcription and Smart Cleanup the right spelling, and stay on this Mac.

RAW SPEECHUm, I I think we should ship Thursday—no, Wednesday.
CLEAN RESULTI think we should ship Wednesday.
App Context
▣ Active application
CodexGoogle DocsMailObsidian

Megaphone uses the active app and window as local hints for tone, spelling, and technical formatting.

Context-aware result
Run git push --force-with-lease, then check the JSON output.

Built around the way you speak.

Live cleanup, automatic language detection, a personal Dictionary, and local Memory work together while you dictate.

Smart Cleanup

Filler words disappear as the thought takes shape.

Here’s to the crazy ones. The misfits. The rebels. The troublemakers. The round pegs in the square holes. The ones who see things differently. Um, they’re not fond of rules, uh, and they have no respect for the status quo.

Multiple languages

Switch naturally. Megaphone follows.

Memory

Megaphone learns the choices you keep making.

“Kuber” preferred over “Cooper”
Concise tone in Slack
Preserve flags in Terminal
Megaphone added to vocabulary

It knows where you’re speaking.

Screen Awareness reads the active app and window title locally, then adapts vocabulary and tone. Switch between the scenes: the same voice sounds natural in Mail and concise in Slack.

Project follow-up
Hi Maya,

Thanks for walking me through the new direction today. The interaction feels much clearer now, and I’m excited to carry it through the rest of the experience.

I’ll send the updated build tomorrow morning.

Best,

Thanks for taking a look — I’d love to hear what you think.

Say “Hey Megaphone.”

Your instruction, active-app context, and nearby words are passed to Apple’s on-device Foundation Model. It returns the answer or rewrite directly at the cursor—no API key, cloud request, or separate AI window.

Runs on your Mac.
Not somebody else’s.
