Whisper AI for your desktop

Whisper AI,
wrapped in a desktop app.

OpenAI's Whisper is the most accurate open-source speech-to-text model ever built. But using it requires the command line. Mumbl wraps Whisper in a native desktop app with a global hotkey, filler word cleanup, text formatting, and paste-anywhere convenience.

"alright so the new API endpoint is returning a 403 on authenticated requests, I think it's a CORS issue or maybe the token isn't being passed in the header correctly, need to check the middleware"

Mumbl output — Documentation

Bug Report: 403 on Authenticated API Requests Observed behavior: Authenticated requests to the new API endpoint are returning a 403 Forbidden response. Suspected causes: CORS misconfiguration blocking preflight requests, or auth token not being attached to request headers correctly. Next steps: Inspect middleware for token injection logic, check CORS headers in the API response, verify token format matches expected schema. Priority: High — blocks authenticated flows.

The problem with cloud transcription

"For years, I relied on transcription tools that were almost good, but they were all closed-source...leaving me wondering where my audio really went."

Whisper is incredible but requires Python, command line, and technical setup. Most people can't use it even though it's free.

"I'll reconsider when local or self-hosted AI is available." — It's available now, in an app.

Mumbl packages Whisper into a native app. Download, install, hit a hotkey, speak. No terminal, no Python, no setup. Just works.

Frequently asked questions

Is this actually using Whisper?

Yes. Mumbl runs OpenAI's Whisper model locally on your device. The model is downloaded once during setup, then all processing happens on your machine. Same Whisper, packaged in a real app.

Do I need Python or the command line?

No. Mumbl handles everything. Download the app, install it, and you're ready. Hit a global hotkey from any app, speak, and formatted text appears. No terminal, no dependencies, no configuration.

What does Mumbl add on top of Whisper?

Global hotkey from any app, automatic filler word removal, text formatting and style options, paste-anywhere convenience, and a native menu bar/system tray app. It turns Whisper from a developer tool into something anyone can use.
