DoneBell — Task Finish Alerts

Get a sound, notification and tab focus when a long browser task finishes.

DoneBell tells you when a long-running browser task finishes, so you can stop checking the same tab over and over. It can monitor supported AI chats for response completion and can also watch a page element you select on other websites. DoneBell includes dedicated support for several popular AI chat services, with generic completion detection available for compatible interfaces. Key features • AI response completion monitoring • Universal element watcher for other browser tasks • Built-in bell or your own local audio files • Local playlists with shuffle, repeat and playback controls • Play, pause, previous, next and track seeking • Live volume control • Per-tab, per-site and global sound settings • Option to keep the current track playing when another task finishes • Browser and system notifications • Optional automatic switching to a finished tab • Flashing DONE status in the tab title • In-page completion controls • Global alert profiles and per-site overrides • Optional Auto-Watch for supported sites • Emergency Stop • Settings export and import • Built-in diagnostics and self-test • 18 interface languages • Customizable fonts, colors and appearance Privacy Manual watching uses temporary browser access after you explicitly activate DoneBell. Auto-Watch is optional and requests access only to the specific supported site you enable. DoneBell does not request access to every website. For supported background completion detection, DoneBell observes only the technical lifecycle needed to determine when a task finishes. It does not read AI prompts or answers. Settings, diagnostic logs and custom audio are stored locally in browser extension storage. Diagnostic reports are never uploaded automatically. DoneBell does not require an account or external backend service. Public Beta DoneBell is currently in Public Beta. Web interfaces can change without notice, so individual integrations may occasionally require compatibility updates. Developed by Generion Lab.
