English and Vietnamese interfaces are available. ACCOUNT AND PLANS Google sign-in is required. The Free plan includes the first 20 results per analysis. Paid Pro unlocks deeper results and MCP integration for Claude Code. Price and duration are shown in the extension. Payment is handled outside the Chrome Web Store. TRANSPARENCY Book analysis data is stored locally. Google sign-in and license checks use our account service. The extension uses your own Amazon browsing session. To obtain regional prices, it can change the session’s Deliver to ZIP code; this can be changed or disabled in Settings and does not edit saved addresses.
