Users who use WhatsApp Web in the browser may miss incoming messages when the WhatsApp tab is not active. This extension displays unread message counts directly on the Chrome toolbar icon badge, allowing users to see notifications at a glance without switching tabs.

1. User installs extension and opens WhatsApp Web. 2. User scans QR code to authenticate with WhatsApp mobile app. 3. Extension monitors the WhatsApp Web tab and parses the page title for unread count (e.g., '(3) WhatsApp Web'). 4. Unread count is displayed as badge text on the extension icon. 5. User clicks extension icon to quickly switch to/focus the WhatsApp Web tab.

Target users: WhatsApp Web users who want browser-level notifications for unread messages / Users who keep WhatsApp Web open in a background tab and want to be alerted to new messages

The extension has very minimal source code (113 lines in background.js). The analysis is straightforward and complete.
Badge count extraction relies on parsing the WhatsApp Web page title format '(N)' which could break if WhatsApp changes their page title format.

Monetization

No paid features detected

The extension has no paid features, subscription logic, payment UI, or feature gating of any kind. It is a simple free utility that monitors WhatsApp Web tabs and displays unread counts as badge text. The only 'pro' keyword match was a false positive in _metadata/verified_contents.json (a Chrome Web Store verification file, not related to premium features). No payment platforms, billing APIs, or upgrade flows exist in the source code.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension itself has no login UI, but its entire workflow depends on the user being logged into WhatsApp Web (https://web.whatsapp.com/). WhatsApp Web requires scanning a QR code with the WhatsApp mobile app to authenticate. The extension checks for the '.landing-wrapper' element (line 74 in background.js) which appears when the user is NOT logged in, and displays an orange 'X' badge as a reminder. Without a valid WhatsApp Web session, the extension cannot display unread message counts or function meaningfully.
