Voice-triggered dictation
Begin dictation with a phrase like “Hey Megaphone.” The app transcribes speech while you keep writing in the app you already use, without switching to a separate chat window.
Overview
Megaphone is a Mac dictation app for fast live transcription, cleanup, and context-aware writing. It is presented as free, private, and open source, with the main workflow designed to keep you in the app you already use.
The site shows a dictation flow that starts with “Hey Megaphone,” then uses Apple’s on-device Foundation Models to rewrite text directly at the cursor. Supporting features include Smart Cleanup, a personal Dictionary, Screen Awareness, automatic language detection, and import/export for dictionary entries.
Features
Inline AI rewrites
The app uses Apple’s on-device Foundation Model for rewrite and cleanup actions, and the site emphasizes that these happen at the cursor instead of in a separate AI interface.
Cleanup modes
Smart Cleanup removes filler words and can apply different cleanup modes, including Smart, Basic, and Exact, so the output can be adjusted for how much correction you want.
Personal Dictionary with import/export
Dictionary lets you store names, acronyms, products, and technical terms so transcription and cleanup keep them spelled consistently. The page also shows import and export for private dictionary data.
App-aware writing
Screen Awareness reads the active application and window title locally and uses that context to adapt tone, spelling, and formatting for the current app.
Language detection and memory
Megaphone shows automatic language detection and local Memory that can learn preferred wording over time, including recurring spelling choices and tone preferences.
