The problem with cloud transcription

"You're renting someone else's hardware when you already own hardware that's faster."

Cloud outages, slow connections, and airplane mode shouldn't stop you from working.

"If it's truly offline, shouldn't it support a one-time purchase model?" — We agree. Lifetime pricing available.

Mumbl runs Whisper AI directly on your machine. Same model, no cloud middleman taking a cut.

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.

We do geological surveys in places where the nearest cell tower is 50 miles away. Mumbl runs completely offline on our field laptops. It changed how we document findings.

Frequently asked questions

Does it really work without internet?

Yes. Mumbl downloads the Whisper AI model once during setup, then everything runs locally on your device. No internet connection needed after that.

Is offline accuracy worse?

No. It's the same Whisper AI model whether it runs on your device or in the cloud. The accuracy is identical because it's the same neural network.

Why do other tools need the cloud?

Most transcription tools charge you monthly for cloud processing because it's a recurring revenue model. Your device is fully capable of running the same AI locally. Cloud transcription is a business model, not a technical necessity.
