Megaphone

Megaphone is an open-source, offline dictation application designed exclusively for Apple Silicon Macs running macOS 13.0 or later. It allows users to quickly transcribe speech into clean, formatted text by simply holding the Fn key and speaking. What sets Megaphone apart is its comprehensive on-device processing; it leverages Apple’s SpeechAnalyzer for real-time transcription and utilizes Foundation Models to enhance accuracy by removing fillers, correcting self-corrections, and adapting to the context of the active app. This results in a seamless, private dictation experience without the need for an internet connection, accounts, or subscriptions. Its native integration with macOS makes it ideal for professionals, writers, and developers seeking a privacy-focused, efficient speech-to-text solution that works directly on their device, ensuring data never leaves the machine.
