Voice-to-text that runs on your Mac. Dictate into any app, transcribe meetings offline, and optionally clean up text with AI. Private by default, no subscription, no account required.
What it does
Private by default
When you use local models, your audio never leaves your Mac. Not even for a second. No server, no upload, no internet required. You can optionally choose cloud transcription models with your own API keys, which keeps your data under your control. Either way, your words stay yours.
Meetings and notes
Record entire meetings fully offline with speaker diarization and automatic chunked transcription. Optionally enable AI-powered summaries with key points and action items using a local or cloud provider. Capture quick voice notes with a separate hotkey. Everything is searchable in your history with audio playback, stats, and full transcripts.
Works in every app
Press a keyboard shortcut, speak, and text appears at your cursor. Slack, Notion, VS Code, your browser, an email draft. Murmur supports push-to-talk, toggle, and auto modes so you can pick what feels natural. Text gets pasted directly into the active app, or copied to your clipboard. 99 languages with auto-detection, so you can switch mid-sentence.
30+ models, your choice
Murmur supports state-of-the-art open source transcription models including multiple Whisper variants (via WhisperKit), NVIDIA Parakeet, and Apple Speech. Need cloud? OpenAI transcription is built in too. Every model shows real benchmark data so you can pick the right balance of speed and accuracy. Download only what you need.
Optional AI cleanup
Turn it on and Murmur fixes punctuation, strips filler words, and adjusts tone. It's context-aware: if you're in a code editor, it preserves technical terms. In an email, it cleans up your voice into clear prose. Works with local AI via Ollama or cloud providers like OpenAI. Off by default.

Frequently asked questions
Is my audio really private?
When you use local models, your audio never leaves your Mac. Transcription happens entirely on-device using Apple's Neural Engine. If you choose to use a cloud model like OpenAI, audio is sent to that provider using your own API key. You're always in control of which engine is active.
What transcription models are supported?
Murmur supports over 30 model variants. Local options include multiple Whisper models (via WhisperKit), NVIDIA Parakeet, and Apple Speech. For cloud transcription, OpenAI is supported with your own API key. Each model shows benchmark data for speed and accuracy so you can make an informed choice.
Does it work offline?
Yes. Once you've downloaded a local model, Murmur works completely offline. No internet connection is needed for transcription, recording, or AI cleanup (if you use a local provider like Ollama). Cloud models naturally require an internet connection.
What languages does it support?
Murmur supports 99 languages with automatic language detection. You can also lock it to a specific language if you prefer. Auto-detection lets you switch languages mid-sentence without changing any settings.
What's the difference between App Store and Direct Download?
Both versions include the full transcription engine, 99 languages, streaming results, AI refinement, meetings, notes, and the statistics dashboard. The Direct Download version adds auto-paste (text goes straight into the active app), browser context awareness, and editor context detection. The App Store version is sandboxed, so you paste manually from the clipboard.
Can I switch between App Store and Direct Download?
No. Each version uses a different payment validation system. A purchase on the App Store cannot be used to activate the Direct Download version, and vice versa. Choose the version that fits your needs before purchasing.
Is there a free trial?
Yes. Murmur includes a 7-day free trial with full access to all features. No credit card required for the Direct Download version. The App Store version follows Apple's standard trial and purchase flow.
What about meetings?
Murmur can record entire meetings, transcribe them with speaker diarization, and generate AI summaries with key points and action items. Meetings are recorded in chunks so nothing is lost if something goes wrong. You can also import existing audio or video files for transcription.
