Seller Info Extractor

WHAT IT DOES

Seller Info Extractor is a browser extension that scans any product page for seller information and displays it in a structured summary. It extracts seller name, rating, address, email, phone, website, about description, joined date, and response time. The tool automatically detects seller information from various page layouts and formats, including seller sections, vendor boxes, store information panels, and product metadata. You can copy the extracted information as plain text or JSON for record-keeping or analysis. The tool is ideal for shoppers who want to research sellers, compare vendors, or keep records of seller information for warranty or contact purposes.

WHERE IT RUNS

Seller Info Extractor runs on any webpage, overlaying a floating panel that does not interfere with page content. It operates entirely in your browser as a lightweight userscript, scanning the DOM for seller-related content. It works on any page, whether static or dynamic, with no external dependencies. All settings are stored locally using GM_setValue—no data is ever sent to any server.

HOW TO USE

After installation, open the floating panel by clicking the extension icon. The panel shows the current status (Enabled or Disabled) and a toggle button to enable or disable the extractor. Click the "Scan" button to extract seller information from the page. The panel displays the seller name prominently with a rating if available, followed by a list of other details (address, email, phone, website, about, joined, response time). Click "Text" to copy the seller information as plain text, or "JSON" to copy it as a JSON object. All settings are saved per website.

REAL MECHANISM — WHY THIS WORKS

Most seller information is scattered across product pages in different formats and containers, making it difficult to extract manually. Seller Info Extractor uses a DOM-scanning approach that identifies seller information using multiple strategies. The tool searches for common seller containers using CSS selectors (.seller, .vendor, .store, .merchant, and their variants). It extracts key-value pairs from these containers using pattern matching for "Key: Value" and "Key - Value" formats. The tool also uses a comprehensive list of seller-related keywords (seller, vendor, store, rating, address, email, phone, website, about, joined, response) to identify relevant information. If no dedicated seller containers are found, the tool falls back to scanning the entire page text for these patterns. The extracted information is cleaned and displayed in a structured format with the seller name prominently shown. The export functions format the data as text or JSON. A MutationObserver detects dynamically added seller information and rescans automatically. This approach ensures accurate, real-time, and fully private seller information extraction without requiring any external services or network access.

THE PANEL

The floating panel is fully draggable and remembers its position per site, snapping to the edges of the viewport when dragged near them. You can collapse the panel to a small icon to minimize screen distraction and expand it back with a single click. The panel is resizable from the bottom-right corner, giving you more space to view the seller details. Press the Escape key to close the panel instantly. The panel remains open across page navigation within the same domain, maintaining your current view state. All preferences—panel position and enabled state—are saved per domain for a seamless experience.

PLEASE NOTE

Seller Info Extractor requires the free BotGentz extension to be installed and enabled, as it relies on the cross-extension messaging API provided by BotGentz for DOM access permissions. The tool extracts seller information using pattern matching and may not detect all seller details on all websites. The accuracy of the extracted information depends on the page structure and formatting. The tool does not modify page content; it only reads and displays information. All settings are stored locally in your browser using GM_setValue. No page content, seller data, or usage information is ever sent to any server. The extension does not read, store, or transmit any personal information. It only scans and displays seller information at your request.
