On-device transcription
for teams that can't risk the cloud.
99% of enterprises are exposed to Shadow AI. Employees use cloud transcription tools without IT approval, sending sensitive data to third-party servers. Mumbl runs entirely on-device — nothing to audit, nothing to breach.

The model runs on your machine. Not theirs.
On-device AI means your voice is processed locally, with no transmission, no storage, no exceptions.
"I've been reading more about how these AI tools work and I realized I don't actually want my voice going to some data center, I want the model running right here on my computer so I know for a fact nothing is being transmitted or stored anywhere outside my own machine"
After researching how AI transcription tools process voice data, the conclusion is clear: server-side processing is not acceptable. The model must run locally on the user's machine. On-device transcription ensures no voice data is transmitted to external servers and no storage occurs outside the user's own hardware.
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 bought a laptop with a neural processing unit specifically for local AI. Mumbl is one of the few apps that actually uses it. Transcription is instant and fully on-device.
On-device means on-device. Not mostly on-device with telemetry. I verified the network traffic. Zero outbound connections. That's what real on-device looks like.
The speed difference between cloud and on-device is real. Mumbl transcribes as fast as I speak with no lag, no buffering, no internet dependency.

The problem with cloud transcription
"99% of enterprises are exposed to Shadow AI, fewer than 1 in 7 have implemented AI governance controls."
All it takes is one employee bringing a cloud note-taker into a meeting, and suddenly everyone's data is on someone else's server.
Vendors may retain recordings, transcripts, and metadata indefinitely or use them to train AI models.
Mumbl runs on each employee's device. No cloud component means no vendor risk, no data retention policies to audit, no breach vector.
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
Can we deploy this across a team?
Yes. Mumbl offers team pricing at Contact us for team pricing. Each installation runs independently on the employee's device — no shared server, no centralized data store.
How does this solve the Shadow AI problem?
Instead of employees using unauthorized cloud transcription tools, give them Mumbl — a sanctioned tool that runs locally. Same functionality, zero cloud risk. IT stays happy, employees stay productive.
What about SOC 2 compliance?
Mumbl simplifies compliance by eliminating the vendor data layer entirely. No audio is transmitted to any server, so there is no third-party data handling to audit or certify.
