Usage

Murmure provides a clean and focused speech-to-text experience. Once launched, simply start recording your voice. The text appears instantly, processed directly on your computer.

Typical use cases include:

• Dictating to any AI prompt (Cursor, ChatGPT, Mistral, Claude code, etc.)
• Writing notes hands-free
• Capturing creative ideas or dictation
• Post processing with a local LLM to translate, fix grammar, etc.

Because all computation is local, no network connection is required.

Installation

Windows (Official)

[!IMPORTANT] Murmure requires Windows 10 or later. Older versions (such as Windows 8.1) are not supported and may result in missing system libraries (e.g. dxcore.dll).

Multiple installation methods are available:

• Using a .msi or setup.exe file:

  1. Go to the release page and download the latest Murmure_x64.msi (or Murmure_x64-setup.exe).
  2. Run the installer and follow the setup wizard.

• Via WinGet:

  1. Open the Console app via the Windows start menu.
  2. Inside the console, paste winget install Kieirra.Murmure and follow the instructions. (--scope user will be available in the future)

[!IMPORTANT] Murmure requires the Microsoft Visual C++ Redistributable to work on Windows. This package is present on most computers, but if you encounter the error message The code execution cannot proceed because MSVCP140.dll was not found. Reinstalling the program may fix this problem., download and install the package from the official page or use this direct download link: https://aka.ms/vc14/vc_redist.x64.exe

⚠️ Antivirus Notice : Some users reported that Kaspersky may block Murmure. If needed, please add Murmure as an exclusion in your antivirus settings.

Linux (Official)

[!NOTE] Wayland: Two shortcut modes are available. KDE Plasma 6, Hyprland, and Sway use the xdg-desktop-portal GlobalShortcuts portal with no manual setup. GNOME defaults to CLI mode: you must configure a custom OS shortcut before using Murmure, and Push-to-talk is not available. See the Linux installation guide and the shortcut configuration guide.

Multiple installation methods are available:

• Quick install via terminal (Debian-based distributions):

  curl -fsSL https://raw.githubusercontent.com/Kieirra/murmure/main/install.sh | sh
  

• Using a .deb file (Debian-based distributions):

  1. Go to the release page and download the latest Murmure_amd64.deb.
  2. Install it: sudo dpkg -i Murmure_amd64.deb

• Using an AppImage:

  1. Download Murmure_amd64.AppImage from the release page.
  2. Make it executable: chmod +x Murmure_amd64.AppImage
  3. Run the AppImage.

MacOS (Official)

1. Download Murmure_aarch64_darwin.dmg from the release page
2. Drag Murmure to the Applications folder, then open it from there.
3. Murmure should ask for permissions to access your microphone and accessibility.
4. Restart Murmure for the permissions to take effect.

[!IMPORTANT] Updating Murmure on macOS from 1.6.0: If you experience issues with Murmure and the shortcuts are not working, please do this exactly in this order, (and "Remove" means not only un-toggling but really removing completely Murmure from the list) :

1. Remove Murmure from System Settings → Privacy & Security → Accessibility.
2. Remove Murmure from System Settings → Privacy & Security → Input monitoring.
3. Install the last version
4. Launch Murmure.
5. Re-grant the Accessibility
6. Re-grant the Input monitoring permission
7. Restart Murmure.

it should work. It's a bit painful but you will not do it again with the next version, it's because 1.6.0 have the same name but is not detected as the same application... so macos is lost.

MacOS - Intel (Official)

1. Download Murmure_x86_64_darwin.dmg from the release page
2. Drag Murmure to the Applications folder, then open it from there.
3. Murmure should ask for permissions to access your microphone and accessibility.
4. Restart Murmure for the permissions to take effect.

The same upgrade note from 1.6.0 applies. See the MacOS section above.

CLI Import (1.8.0)

Murmure supports importing a .murmure configuration file via the command line (murmure import config.murmure), useful for mass deployment or sharing settings across machines. A --strategy merge option is available to keep existing settings. See the CLI documentation for details.
