The local AI meeting note taker for Mac
A local AI meeting note taker records, transcribes, and summarizes your meetings on your own device, without uploading meeting content to the cloud. In Mumble’s Local Mode, all three steps run on your Mac: audio capture, real-time transcription with speaker labels, and AI summaries. No meeting bot joins your call, and no meeting content is sent to any server.
Built so your data never has to leave.
100% on-device
Every step runs on your Mac. When a call starts, Mumble captures the audio directly from macOS, transcribes it with an on-device speech-to-text model, labels each speaker, and generates the summary with a local language model. No audio, transcript, or summary leaves the machine.
No bots join your calls
Most AI note takers join your meeting as a visible participant. Mumble does not. It captures system audio natively in the background, so nothing appears in the Google Meet, Zoom, or Teams participant list. Your clients, patients, or sources never see a third-party note taker on the call.
Real-time speaker labels
Mumble transcribes the meeting as it happens and labels who is speaking in real time. You read “Sarah said X, then Mike asked Y” instead of one undivided block of text. Because transcription is local, there is no upload-and-wait delay before you can read or search the transcript.
Works fully offline
Local Mode does not need an internet connection. Once Mumble is installed, you can record and transcribe a meeting on a plane, in a secure facility, or anywhere with no network. Turn off Wi-Fi mid-meeting and the transcript keeps running, because nothing was being sent anywhere to begin with.
Don’t just trust us. See it.
Mumble is built so you can prove to your client, source, or patient that nothing leaves your machine. Pull the ethernet cable. Turn off Wi-Fi. Your transcript keeps running.
Airplane mode works fine.
Turn off Wi-Fi mid-meeting. The transcript keeps streaming. Because nothing was being sent anywhere to begin with.
You own the files.
Recordings, transcripts, and notes live on your Mac. Delete them, move them, back them up. Your machine, your rules.
It all happens on your Mac.
Transcription, speaker labels, and summarization run on your Apple Silicon. No data is sent to any cloud service.
Your client never sees a bot.
Mumble works in the background. On Google Meet, Zoom, or Teams, nothing extra appears in the participant list.
Local and Cloud, at your choice.
Mumble includes both modes, and you can switch anytime. You can even set them per feature, so meetings can run in Local Mode while another feature runs in Cloud Mode. Local Mode keeps everything on your Mac. Cloud Mode adds advanced AI features and runs comfortably on lighter hardware.

FAQ
What is a local AI meeting note taker?
A local AI meeting note taker records, transcribes, and summarizes meetings on your own device instead of in the cloud. With Mumble's Local Mode, the audio, the transcript, and the AI summary are all processed on your Mac.
In Local Mode, does any of my meeting data go to the cloud?
No. This is the part that sets Local Mode apart. Some tools say "audio never leaves your device" but still send the transcript to the cloud to generate the AI notes. In Mumble's Local Mode, all three steps stay on your Mac: audio capture, speech-to-text, and AI summary generation. There is no cloud step anywhere in the workflow.
Does Local Mode work offline?
Yes. Once Mumble is installed, Local Mode records and transcribes meetings with no internet connection. You can turn off Wi-Fi mid-meeting and the transcript keeps running, because nothing is being sent anywhere.
Is "bot-free" the same as "local"?
No. Bot-free means no AI participant joins your meeting. Local means the meeting audio, transcript, and summary are all processed on your device. A tool can be bot-free and still process meeting content in the cloud. Mumble's Local Mode is both bot-free and local.
How is Local Mode different from Granola or Otter?
Granola is bot-free, and Otter has a bot that joins the call. Either way, both still send your meeting content to the cloud to process it. They may not store your data, but it still leaves your device. Mumble's Local Mode keeps audio, transcription, and summarization on your Mac.
Can I switch between Local Mode and Cloud Mode?
Yes. You can switch anytime, and you can set the mode per feature. For example, you can keep meetings in Local Mode for privacy while using Cloud Mode for another feature. Local Mode is built for private and offline use. Cloud Mode adds advanced AI features such as Voice Skills and AI Chat, and runs well on lighter hardware.
Which meeting apps does it work with?
Mumble captures system audio on your Mac, so it works with Google Meet, Zoom, Teams, and any app that plays audio on the machine. It needs no browser extension and no meeting bot.
Who is Local Mode for?
Local Mode fits anyone whose meetings include confidential information: founders, consultants, lawyers, doctors, researchers, and anyone under an NDA or a client or employer restriction on cloud transcription.
Is the transcription quality as good as cloud tools?
On-device transcription on Apple Silicon handles normal meeting conditions well, with speaker labels and support for multiple languages. Local Mode is the right choice when keeping meeting content on-device is the priority. Cloud Mode is available when you want advanced AI features on top of the transcript.
What hardware do I need for Local Mode?
Local Mode runs on Apple Silicon Macs (M1 or later) with macOS 15 or later. We recommend 24GB of unified memory or more for the full Local Mode experience. Mumble still runs on Macs with less memory, but Local Mode is not recommended there, because limited memory significantly affects performance. On lighter hardware, Cloud Mode is the better fit.
