Designed for law firm security

Attorney-client privilege
meets voice-to-text.

Cloud transcription creates discoverable records on third-party servers. One subpoena and your client's words are in someone else's hands. Mumbl runs on your device — nothing to discover, nothing to subpoena.

No third-party servers
Nothing discoverable
Zero vendor trust required

The problem with cloud transcription

"Wait, are we being recorded?" — the moment client trust breaks. Cloud tools that auto-join meetings create this exact scenario.

Lawyers using personal AI tools on client calls expose the entire firm. Shadow AI is a firm-wide liability.

"Products designed specifically for lawyers generally comply with applicable legal and ethical requirements, though you must familiarize yourself with the product's terms of service."

Mumbl eliminates the third-party risk entirely. No terms of service to parse. No vendor to trust. Your device, your data, your control.

Three steps. That's it.

1

Hold down Option + Space

Or customize your own hotkey

2

Talk naturally

Say what you're thinking, ramble, use filler words. Mumbl cleans it all up.

3

Release

AI formats it instantly in your chosen style and pastes it wherever your cursor is.

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.

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!

Our risk committee rejected every cloud transcription vendor. Mumbl was approved in one meeting because there's no third-party data handling to evaluate. Each attorney's installation runs independently on their own device.

We deployed Mumbl across 40 attorneys and the Shadow AI problem disappeared overnight. Everyone has a sanctioned tool that actually works, and IT doesn't have to worry about client data leaving the network.

As a firm administrator, the per-seat licensing model makes budgeting simple. But what sold us was the architecture: no servers, no breach vector, no vendor to audit annually.

Need Mumbl for your law firm?

Deploy across your firm with per-seat licensing. Each installation runs independently on the attorney's device. No shared servers, no centralized data store, no firm-wide breach vector.

Frequently asked questions

Can opposing counsel subpoena Mumbl transcripts?

Mumbl stores nothing. Transcription happens in real-time on your device and the text is pasted where your cursor is. There is no Mumbl server holding your data, no cloud backup, no vendor to subpoena.

Is this approved for use with client data?

Mumbl processes everything locally — no data leaves your device. Consult your firm's IT policy, but the architecture eliminates the third-party data risk that most compliance reviews are concerned about.

Can I deploy this firm-wide?

Yes. Team pricing starts at $29/seat/month or $19/seat/year. Each installation runs independently on the attorney's device. No shared servers, no centralized data store, no firm-wide breach vector.
