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.
macOS & Windows — Deploy locally, no vendor risk
"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.

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 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.

Deploy across your organization with per-seat licensing. Each installation runs independently on the employee's device. No shared servers, no centralized data store, no enterprise-wide breach vector.
Yes. Mumbl offers team pricing at $29/seat/month or $19/seat/year with a minimum 3-seat pilot. Each installation runs independently on the employee's device — no shared server, no centralized data store.
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.
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.
