A lightweight Chrome extension that plays a chime and shows a desktop notification when Claude finishes a response, so you can multitask freely without watching the tab. It detects when a response finishes streaming, then plays your selected sound and, if enabled, shows a notification you can click to jump back to the Claude tab.
- Audible chime when Claude finishes generating a response
- Desktop notification that focuses the Claude tab when clicked
- Four built-in sounds (Chime, Bell, Ding, and Soft), all generated with the Web Audio API (no audio files, no network calls)
- Adjustable volume with a live preview button
- Toggle sound and notifications independently
- Fully private. No data is collected, stored externally, or transmitted
The easiest way is to install directly from the Chrome Web Store.
