One key difference of Mumble is that we offer two ways to process your audio. Mumble uses the most advanced AI models to turn your voice into accurate transcriptions, structured notes, and actionable insights. Your audio is processed in real time and is not stored by Mumble.

​
Cloud Mode

Cloud Mode optimizes speed and accuracy, powered by the latest large language models. Audio is processed in the cloud, encrypted in transit and at rest, and never stored after processing. With Cloud Mode you get real-time transcription with speaker labels, best-in-class accuracy across 50+ languages, and smart summaries with action items and follow-ups. Requires internet.

​
Local Mode

Local Mode gives you full on-device privacy. Your audio never leaves your Mac. And you can still record, transcribe, and dictate even without an internet connection. Local Mode is a core part of what makes Mumble different, and it will be free forever. Local Models are available for Meetings, Voice Notes and Dictation. What runs locally today depends on the feature:
  • Dictation. Fully local. Everything from speech recognition to text output happens on your Mac.
  • Meetings and Voice Notes. Recording and transcription run entirely on your device. Summaries and structured notes currently use cloud-based language models to process the transcript (your audio is never uploaded, only the text). We are actively working to bring summary generation fully on-device in a future update.
To use Local Mode, you need to download the local model first. You can do this during onboarding when you choose your processing mode, or anytime later in Settings > Processing Mode. Apple Silicon with 24GB+ memory is recommended. Note: Local dictation model works best with a single language. Selecting multiple languages may reduce accuracy.

​
Set it per feature

You don’t have to pick one mode for everything. In Settings > Processing Mode, each feature has its own Cloud/Local toggle. Use Cloud for everyday meetings where you want the best accuracy, and Local for sensitive conversations where privacy matters most.
