Universal approach — mute at the macOS level

macOS lets you silence any app's sound without disabling its notifications. The full visual walkthrough lives on the universal macOS method page. The short version:

  1. Open System Settings → Notifications.
  2. Scroll to Safari in the application list and click it.
  3. Turn off Play sound for notifications.
  4. Safari keeps showing banners and badges — just no audio.
macOS System Settings → Notifications → Safari
System Settings → Notifications → Safari → toggle off Play sound for notifications.

How Chirpy fills the gap

Chirpy reads the notification title and matches it against your rules. That means you can do things Safari can't on its own — different sounds per channel, per person, per keyword, per server. Three quick examples:

  • Boss mentions only: a distinct chime when their name appears in any Safari notification.
  • Urgent channel: a louder sound when the notification contains #urgent or #critical.
  • Silence everything else: a rule that matches all other Safari notifications with no sound — banners still appear, your day stays quiet.

Want sounds that actually mean something?

Chirpy adds rule-based custom sounds on top of macOS notifications. One sound for Safari mentions, another for your calendar, silence for the rest.
