Know when you're getting loud.

Mezzo gives you quiet, visual feedback when your speaking volume rises — so you can adjust without anyone else noticing. How it works

Try Mezzo

You can stop anytime. Nothing is saved.

No recording. No transcription. Just volume.

How it works

Mezzo monitoring screen
  1. 1

    Calibrate

    Speak normally for a few seconds. Mezzo sets your baseline.

  2. 2

    Talk

    When you're in range, Mezzo stays invisible.

  3. 3

    Notice

    If you get louder, the feedback gradually appears. Ease up? It fades away.

What Mezzo is good for

  • Open office huddles
  • Calls from a shared desk
  • Cafés, lobbies, and common areas

Works in a browser tab or picture-in-picture.

What it doesn't do

Mezzo doesn't record audio, transcribe speech, or send anything anywhere. Your mic data stays in your browser and disappears when you close the tab.
