## What it does

- Streams microphone audio into Apple's SpeechAnalyzer while the user talks, so transcription is nearly complete when the shortcut is released.
- Runs Smart Cleanup with Apple's on-device Foundation Models framework and falls back to a fast deterministic pass for fillers, stutters, repetitions, and spacing.
- Offers Inline AI (Alpha): begin a dictation with “Hey Megaphone” to ask a question, generate text, or transform the previous dictation using same-app screen context.
- Learns a private personal Dictionary of names, technical terms, acronyms, and exact heard-to-written corrections.
- Uses active-app and window context to preserve technical syntax and adapt output to where the user is typing.
- Supports hold-to-talk, tap-to-toggle, Edit Mode, voice macros, multiple languages, configurable microphones, clipboard restoration, and a run log.

## Privacy

Speech recognition, cleanup, Dictionary learning, and Inline AI run on the Mac. Megaphone does not require an API key and does not upload voice recordings or transcripts to a Megaphone server.

## Key shortcut

Hold Fn to dictate by default, or press Command-Fn to toggle recording. Shortcuts are configurable.
