Cursor-first dictation
Start dictation with “Hey Megaphone” and get transcription and rewrites without opening a separate chat window or leaving the cursor.
Megaphone
Megaphone is a free, open-source Mac dictation app for live transcription, cleanup, and inline rewriting at the cursor. It uses Apple’s on-device Foundation Model plus a private Dictionary to adapt text while you work in other Mac apps.
Overview
Megaphone is a free, open-source dictation app for Mac that focuses on fast live transcription, cleanup, and inline rewriting at the cursor. It is built to work inside the app you are already using, rather than sending you to a separate chat or editing interface.
The product emphasizes local processing on macOS. The site says dictation can begin with “Hey Megaphone,” and that the app uses Apple’s on-device Foundation Model, Screen Awareness, and a personal Dictionary to adapt spelling, tone, and formatting while you write.
Features
Inline AI
The app uses Apple’s on-device Foundation Model for inline rewriting, so changes return directly in the app you are already using.
Smart Cleanup modes
Smart Cleanup removes filler and sharpens spoken text, with modes shown on the site including Smart, Basic, and Exact.
Personal Dictionary
A private Dictionary lets you save names, products, acronyms, and technical terms so transcription and cleanup use the right spelling.
App-aware writing
App Awareness reads the active app and window title locally to adjust tone, spelling, and formatting for the context you are writing in.
Automatic learning and dictionary transfer
Megaphone includes automatic learning, where words become active after three successful dictations, and dictionary data can be exported or imported as JSON.
Use cases
Hands-on dictation
Dictate text directly into the app you are already working in, then keep typing without switching to a separate editor or chat interface.
Live cleanup while speaking
Turn spoken drafting into cleaner text by removing filler words and applying a concise rewrite at the cursor.
Vocabulary management
Store names, acronyms, product terms, and technical language in the Dictionary so they stay consistent across dictations.
Context-aware writing
Let the app adapt wording, spelling, and formatting based on the active app, such as Mail, Slack, or a code-oriented window.
Move your dictionary between Macs
Export Dictionary data as JSON and bring it to another Mac if you want to keep the same vocabulary setup across devices.
