Works on a plane. Works in the middle of nowhere.
Mumbl runs entirely on your device. No internet required. Ever.
"I'm on flights a lot and in areas with bad wifi and I still need to be able to dictate notes and have them come out formatted properly without waiting to be online or worrying about whether the thing even works when I'm not connected"
A core workflow requirement is the ability to dictate and format notes without any internet connection. Whether in transit or in low-connectivity environments, transcription must function fully offline, producing clean, formatted output immediately and without delay.
What people are saying
This is the simplest way to 10X your productivity.
I can finally talk to Claude Code with only two keys.
My favorite thing about Mumbl is its simplicity. There aren't any loops you have to go through to make it work and it's intertwined with my device really well. Right now I mainly use Mumbl for school work!
I was unsure on how I would feel talking to my computer, but I figured I'd give it a try. Turned out 10x better than I had expected. It's crazy how much time has already saved me!

I'm on a plane 100 days a year. Now I dictate the whole flight and Mumbl transcribes everything locally. No Wi-Fi needed. I land with everything already written.
We do geological surveys in places where the nearest cell tower is 50 miles away. Mumbl runs completely offline on our field laptops. It changed how we document findings.
When our office internet went down, I was the only one still working because Mumbl doesn't need a connection. Everyone else was waiting for cloud tools to come back online.

The problem with cloud transcription
"You're renting someone else's hardware when you already own hardware that's faster."
Cloud outages, slow connections, and airplane mode shouldn't stop you from working.
"If it's truly offline, shouldn't it support a one-time purchase model?" — We agree. Lifetime pricing available.
Mumbl runs Whisper AI directly on your machine. Same model, no cloud middleman taking a cut.
Your voice never leaves your device
Mumbl processes everything locally using Whisper AI. No cloud uploads. No servers. No data collection. Your words stay yours.

Frequently asked questions
Does it really work without internet?
Yes. Mumbl downloads the Whisper AI model once during setup, then everything runs locally on your device. No internet connection needed after that.
Is offline accuracy worse?
No. It's the same Whisper AI model whether it runs on your device or in the cloud. The accuracy is identical because it's the same neural network.
Why do other tools need the cloud?
Most transcription tools charge you monthly for cloud processing because it's a recurring revenue model. Your device is fully capable of running the same AI locally. Cloud transcription is a business model, not a technical necessity.
