Meeting notes that never leave your computer.

Murmur records both sides of any call, transcribes it on your computer, tells the speakers apart and writes the notes. Nothing is uploaded, and there’s no account to make.

  • Both sides of any call. Zoom, Meet, Teams or a phone call through your laptop. No bot joins the meeting.
  • Transcribed on your computer. Speech recognition runs on your Mac or PC, live, even in airplane mode.
  • Knows who said what. Your side is labelled You; other voices are told apart, and remembered once named.
  • Notes that write themselves. Key points and action items, with who owns each one and when it’s due.
  • A summary you can check. A small AI model on your computer links every point to the moment it was said.

How we build

Three rules, one for each ribbon in our logo.

  1. 01

    Your files stay yours.

    Recordings, notes and files stay on your own device. Murmur transcribes without uploading a word, and Quick Switch sends files straight from one phone to the other, never through our servers.

  2. 02

    No account, ever.

    You shouldn’t need a password to clean a speaker. Open the app and it works: no sign-up, no profile, no email address to hand over.

  3. 03

    One job, done properly.

    Each app does one thing well, without menus full of features you didn’t ask for. And when something breaks, you can email the people who built it.
