Same AI.
Your hardware. No cloud.
Cloud transcription tools charge you monthly to run AI on their servers. Your computer can run the same model locally. Mumbl proves it — full Whisper AI transcription without uploading a single byte.
macOS & Windows · iOS coming soon — Same AI, your machine

AI transcription with zero cloud contact.
Not "privacy-first marketing." Literally no data leaves your device. Ever.
"I work with confidential information every day and I've been burned before by tools that say they're private but then you read the terms and they're storing everything, I just need AI transcription that genuinely doesn't touch any cloud, period"
Working with confidential information daily requires transcription tools that are verifiably private. Prior experience with tools claiming privacy while storing data server-side has eroded trust. The only acceptable solution is AI-powered transcription that operates entirely on-device with zero cloud interaction.
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've been running local LLMs for a year and Mumbl was the missing piece. Whisper running natively with a clean UI. No API keys, no cloud endpoints, no data leaving my hardware.
As a security researcher, I verified it with a packet sniffer. Zero outbound connections during transcription. This is how AI tools should work.
I tried building my own local transcription pipeline with Whisper and Python. Mumbl packages the same technology into something I can actually use every day.

The problem with cloud transcription
"You're renting someone else's hardware when you already own hardware that's faster."
Cloud transcription is a business model, not a technical necessity. The AI runs fine on your machine.
"Cloud transcription persists through inertia, not technical necessity."
Mumbl runs the same Whisper AI model that cloud tools use — just on your device instead of theirs. Same accuracy, no data exposure.
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
Is local AI as accurate as cloud AI?
Yes. Mumbl uses the same Whisper model that cloud services use. The model runs identically whether it's on their server or your machine. The accuracy is the same because it's the same neural network.
Won't it slow down my computer?
Mumbl processes audio in real-time. A typical transcription takes just a few seconds. Modern computers — especially Apple Silicon Macs — handle Whisper AI comfortably without noticeable impact.
Why do other tools charge for cloud processing?
Recurring revenue. Cloud processing lets companies charge monthly subscriptions for something your device can do locally. Mumbl offers lifetime pricing because there are no server costs to pass on to you.
