Your voice, your device, your privacy. Murmur turns speech into text entirely on-device. No cloud. No accounts. Just fast, private dictation in any app.
Murmur turns your voice into text — entirely on your iPhone. No internet, no accounts, no data leaving your device. Powered by WhisperKit, Murmur runs a real speech recognition model locally, so your words stay yours.
Use it as a standalone app or switch to the Murmur keyboard in any app — Messages, Notes, Mail, wherever you type. Tap the mic, speak naturally, and your transcription appears instantly.
Most voice-to-text apps send your audio to the cloud. Murmur doesn't. It runs WhisperKit directly on your iPhone — no server, no account, no data collection. The new keyboard extension lets you dictate in any app, and v2.2 makes the whole flow feel faster and more polished in both light and dark mode.
• 100% on-device transcription
• Works offline, no cloud processing
• Custom keyboard for dictation in any app
• Smart warm/cold engine — fast when ready, clear when loading
• Dark mode designed to feel intentional, not just inverted
• Copy, share, or search your transcription history
Your voice. Your words. Your device.
Works like Wispr Flow but I don’t need to pay for it. Works really well.

I like the idea of this app, locally stored whisper model and no dependent on online connection for Dictation. However, the app crashes on start for me
Voice dictation just got smarter. Murmur now automatically detects when you stop speaking and begins transcription — no need to tap stop. The keyboard communicates with the app instantly via Darwin notifications instead of polling, so dictation results appear faster. We also added memory-aware model management that gracefully unloads and reloads WhisperKit when your device needs resources.
New in this update:
• Smart silence detection that auto-stops recording when you pause
• Instant keyboard-to-app communication
• Full dark mode support with Auto, Light, and Dark options
• Redesigned Settings as a full page
• Full Access prompt guides you through complete setup
• Performance and layout improvements throughout
