GChat Custom Notifications

GChat Custom Notifications replaces Google Chat's default notification system with a fully customizable sound alert. Whether you're deep in focus mode or working with multiple tabs open, never miss an incoming message again. Choose your notification sound: - 🎵 Built-in file — drop any MP3 or WAV into the extension folder - 📁 Upload a file — load any audio file directly from your device (up to 4 MB) - ▶ YouTube clip — paste any YouTube URL and pick the exact seconds to play Fine-tune every detail: - Set start and stop times to play only the part of the audio you want - Adjust volume independently from your system settings - Anti-spam cooldown prevents the sound from firing too frequently Smart detection: - Only triggers on incoming messages — your own messages are ignored - Fingerprints each message to avoid duplicate alerts on page re-renders - Automatically re-syncs when you navigate between conversations Privacy first: everything runs locally in your browser. No data is collected, no servers are involved, no account required. Works silently in the background. Enable or pause notifications instantly from the toolbar popup.
