I love this app but chrome is saying This extension may soon no longer be supported because it doesn't follow best practices for Chrome extensions. Important Notice: Chrome will soon disable this extension. It uses an older version of Manifest that Chrome no longer supports. To the developer please update this so it will continue to work.

AI product read

Amazon inventory/stock counter that shows the quantity of stock available for each seller on an Amazon product listing

Amazon sellers need to know competitor inventory levels to make informed sourcing and pricing decisions. This extension automates the process of checking stock quantities by adding items to cart and determining available inventory.

User visits any Amazon product page, clicks the 'Count Stock!' button or the extension icon, and the extension automatically adds items to cart with increasing quantities to determine each seller's available stock. Results are displayed in a widget showing seller name, quantity, price, type, rating, and condition. Users can filter results and export data.

Target users: Amazon sellers conducting competitor research / Amazon FBA/FBM sellers analyzing market inventory / E-commerce researchers studying Amazon product availability

Extension uses Manifest V2 (being deprecated by Chrome as noted in the extension itself), though store listing shows manifestVersion 3 - may have been partially updated
The promotional notifications for third-party products (RevSeller, DS Amazon Quick View) could be misleading as they contain paid/trial language but are not features of this extension
No backend API endpoints found - extension operates entirely client-side by manipulating Amazon's cart system

Monetization

No paid features detected

The extension is completely free to use. The store description explicitly states: 'Premium features may be added in the future, but the stock counter is completely free to use.' No payment processing code, subscription logic, or billing APIs found in source. The keyword matches for 'trial' and 'premium' are false positives - 'trial' appears only in CSS class names for promotional notifications about third-party products (RevSeller), not for the extension itself.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension explicitly states in its store description: 'You do not need to create an account or signup for anything. You can add the extension and start using it immediately.' No login UI or authentication code found in source files. The extension works directly on Amazon pages without requiring any account.
