Every cloud dictation tool listens through someone else's servers. Descript uses Amazon Mechanical Turk workers who listen to voice samples. Rev sends files to 60,000+ freelancers. Mumbl processes everything on your device. Nobody else hears a word.
macOS & Windows — Truly private
"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.

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 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.

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.
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.
Mumbl collects nothing. No audio, no transcripts, no metadata, no usage analytics from the transcription process. The app runs locally and that's it.
