You can't reset your voice like a password. Once your audio is on someone else's server, it's there forever. Mumbl keeps your voice where it belongs — on your machine, under your control.
macOS & Windows — Your voice, your device
"You can't reset your voice. Once leaked, they're compromised forever. Attackers can use voiceprints for authentication bypass, identity fraud, or deepfake generation."
"Audio that never leaves your device cannot be part of a server-side breach."
Metadata often remains stored even when content is deleted. Cloud transcription tools retain more than you think.
Mumbl has no servers, no cloud, no API calls. Your audio is processed on your machine and nowhere else.

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'm not a tech person but I understand that if it stays on my computer, nobody else can see it. That's all I needed to know about Mumbl. It just works and I don't have to worry.
I was afraid of voice-to-text because I didn't want my personal notes on the internet. Mumbl stays completely on my computer. My daughter helped me set it up and now I use it every day.
Simple, stays on my computer, and works without internet. That's exactly what I was looking for. I use it for emails, letters, and just getting my thoughts down faster.

Literally no servers. Mumbl doesn't have a cloud backend for transcription. The AI model runs on your computer. We couldn't access your audio even if we wanted to — there's nowhere for it to go.
App updates are downloaded through standard update channels (like any desktop app). But the transcription process itself is 100% local — no audio data is ever involved in updates or any network communication.
Your voice is a permanent biometric identifier. Unlike a compromised password, you can't change your voice. Voice data can be used for authentication bypass, identity fraud, and deepfake generation. Keeping it off other people's servers is the only real protection.
