Murmur is a macOS menu bar app for push-to-talk dictation that transcribes speech to text anywhere you type, using your own OpenAI API key. It offers features like push-to-talk/toggle shortcuts, real-time transcription, post-processing modes (translation, cleanup, commit messages), and automatic language detection. The project is notable for being an open-source, bring-your-own-key alternative to paid dictation apps, with privacy-focused design (audio goes directly to OpenAI) and clear setup instructions.

Target audience: macOS developers, writers, and power users who want customizable, privacy-aware dictation integrated into their workflow
