Chirpy

The product is a macOS menu bar app that assigns custom notification sounds by app, channel, person, or keyword so users can identify urgency and sender without checking the screen, addressing the problem of identical system sounds causing constant context switching. It sells to individual Mac users and professionals who receive high volumes of notifications from Slack, Teams, Discord, email and other apps. It is delivered as a lightweight 7.8 MB app that runs locally on macOS via the Accessibility API with no account or connection to messaging APIs.
