Chirpy is a Mac menu bar app that plays a different notification sound based on rules you write. Per Slack channel, per Teams channel, per Discord server, per contact in Messages, per sender in Mail, per app in Notification Center.

The problem: macOS only lets you turn a notification sound on or off per app. You can't give a different sound to a specific channel, sender, or keyword. So your manager DMing you, a meme in #random, and production going down all make the same ping. You end up checking your laptop every single time.

Chirpy adds that missing layer. You write rules and each one plays whatever sound you pick. After a few days you stop opening Slack "just to check" because your ears already know what happened.

Example setup:

#deploys → typewriter ding
#incidents → distinct urgent tone
DMs from your manager → small harp
Messages from your partner → wind chime
Emails from Stripe → cha-ching
Everything else → soft chime at 30% volume

Features:

Works with any app in macOS Notification Center (Slack, Teams, Discord, Mail, Messages, Calendar, browser push, more)
72 built-in sounds across nine categories, or upload your own (.mp3, .wav, .caf)
AND/OR matching, priority ordering (most specific rule wins), per-rule volume
