User installs extension → opens a Google Meet call → clicks extension icon → adjusts volume slider in popup → all participant audio/video elements are scaled to the selected volume client-side

Target users: Google Meet users who need finer volume control / Accessibility users who need volume adjustments / Frequent video meeting participants

Source code is minified, making some edge cases harder to verify, but core logic is clear from readable snippets
Cannot verify if Google Meet itself requires login for all use cases (e.g., guest joins) - scoped as destination_service

Monetization

No paid features detected

No payment platforms, billing APIs, subscription logic, or upgrade UI detected. The extension is a simple free utility. The 'pro' keyword hits in static analysis are from minified JS containing words like 'prototype' and 'protocol', not paid feature references.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension itself has no login UI or auth flow, but it only activates on meet.google.com/* pages. To use Google Meet, users must be logged into a Google account. The extension's core workflow (adjusting volume during a Meet call) requires being on a logged-in Meet session.
