nobody else can hear.

"um so I wanted to jot this down real quick uh the new product spec changes we talked about in standup today the API should not be sending data anywhere external and we need to document that clearly before the release"
Following today's standup discussion, the product specification has been updated to reflect a critical architectural decision: all API calls must remain local and no data should be transmitted to external servers. This constraint must be clearly documented prior to release to ensure compliance and user trust.
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 dictate everything from client notes to personal journal entries. Knowing that nobody else can hear my recordings isn't just a preference, it's a requirement. Mumbl is the only tool I trust.
After reading about Descript's Mechanical Turk workers and Rev's 60,000 freelancers, I realized no cloud tool is truly private. Mumbl processes everything locally. Zero human ears, zero servers.
Private by architecture, not by policy. That's what sold me. Mumbl physically can't send my audio anywhere because there's nowhere for it to go. Try verifying that with any cloud tool.

The problem with cloud transcription
"60,000+ freelance transcriptionists at Rev can access your files — anyone with a confidentiality agreement can see sensitive recordings."
Descript uses Amazon Mechanical Turk workers who listen to voice samples. No standard 2FA.
"Free transcription tools present hidden risks: users may not realize their data fuels the vendor's business model."
Mumbl is private by architecture, not by policy. Your audio physically cannot leave your device because there is no cloud component.
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
How do I know it's actually private?
Mumbl processes audio using Whisper AI that runs on your device. There is no network call, no API endpoint, no server to send data to. You can verify this by using Mumbl completely offline — it works the same way.
What's the difference between "private by policy" and "private by architecture"?
Private by policy means a company promises not to look at your data (but technically could). Private by architecture means the system physically cannot access your data because it never leaves your device. Mumbl is the latter.
Do you collect any data at all?
Mumbl collects nothing. No audio, no transcripts, no metadata, no usage analytics from the transcription process. The app runs locally and that's it.
