PopSlack plays custom sounds for Slack DMs, mentions, and channels โ automatically, in the background. Never miss an important message again.
macOS 13 Ventura or later ยท Installation guide โ
PopSlack is a tiny menu bar app that stays out of your way until Slack needs your attention.
Assign any .mp3, .wav, or .aiff file to any rule. Air horn for your boss. Silence for everyone else.
Trigger on a specific person's DMs, a specific channel, any mention, or every Slack notification.
Rules are evaluated top to bottom โ first match wins. Drag to reorder in seconds.
Set different volumes for different rules. Urgent channels can be louder than casual ones.
No network requests. No Slack API. No account. Only reads the notification banner text that's already on your screen.
Installs a LaunchAgent so PopSlack starts automatically every time you log in. No manual setup.
No Slack API. No login. No background syncing. Just macOS doing what it already does.
When you're away from Slack and a message arrives, macOS shows a notification banner as usual.
Using the macOS Accessibility API, PopSlack instantly reads the sender and message from the banner โ the same text you'd see with your own eyes.
Rules are checked top to bottom. The first one that matches the sender or channel fires its sound.
The sound plays immediately at the volume you set. That's it โ no latency, no fuss.
Download, install, grant two permissions. Done.
