# Offline dictation: private voice to text, open source | Dimmy > Offline dictation for Mac and Windows. Local Whisper or Parakeet turns speech into text on-device, no audio leaves your machine. Open-source, private, no account. Source: https://dimmy.app/offline-dictation/ offline dictation # Offline dictation that never leaves your machine Dimmy is a private, offline voice-to-text app for macOS and Windows. Press a hotkey, talk, release, and a local model (Whisper or Parakeet) transcribes your speech on-device. No audio is sent to the cloud, and dictation audio is not kept unless you turn on audio in history. An optional local AI pass cleans up grammar, punctuation, and tone across 13 styles, then the text pastes straight into whatever app you're in: an editor, a browser, a chat window, or a terminal. With Whisper it handles up to 99 languages with automatic detection, and you don't need an account. The alternatives ask you to compromise. Dragon is offline but costs $699, runs on Windows only, and lost its Mac app back in 2018\. Cloud dictation apps send your audio to a server to transcribe it. Dimmy is open source under the AGPL-3.0 and a native app (not an Electron wrapper), so you can read the code and build it yourself for free.

Works on a plane: with local models, dictation keeps working in a tunnel, on a flight, or anywhere with no internet. Truly open source: AGPL-3.0, so you can inspect the code and build it yourself for free. Built for accessibility and RSI: push a hotkey and talk, fully hands-free input that reduces typing strain. Great for developers: dictate into terminals, editors, commit messages, and chat, with an optional local AI pass to clean up grammar. Modern and maintained, unlike $699 Dragon (Windows-only, no Mac since 2018): a native app with up to 99 languages (Whisper), command mode, and meeting recaps in the same app. --- frequently asked ## Private, offline dictation for Mac and Windows.
