Open-source Mac dictation App that's 100% on-device
Hold Fn, speak, and Megaphone types clean text into any Mac app. Apple’s SpeechAnalyzer transcribes as you talk, while on-device Foundation Models remove fillers, fix self-corrections, adapt to app context, and power inline voice commands. No account, API key, subscription, or server. Free, MIT-licensed, and native to Apple silicon Macs running macOS 26.
