Appliance Manual Quick-Lookup by Model Number

WHAT IT DOES

This userscript helps you quickly find manuals and support information for appliances by extracting model numbers from any webpage. It scans any webpage for appliance model numbers, brand names, and product details, then provides a quick-lookup interface to search for and link to online manuals, support pages, and troubleshooting guides. It extracts model numbers using regex patterns (e.g., letters + numbers, formats like "ABC123"), identifies brands from common names (Samsung, LG, Whirlpool, GE, Bosch, Maytag, KitchenAid, Frigidaire, Kenmore, Miele, and more), and generates search URLs for major appliance manufacturers. The script suggests manual download links, displays a list of support resources, and allows you to save model numbers with notes for future reference. It also detects appliance categories (washer, dryer, refrigerator, oven, dishwasher, etc.) based on page context.

WHERE IT RUNS

The script works on any webpage with appliance listings, product pages, reviews, or any page containing model numbers. It runs entirely within your browser, reading only the visible content of the current page. It does not track your browsing history, access other tabs, or send any data externally. All model data is processed and stored locally.

HOW TO USE

After installation, open the panel by clicking the tool's icon in the BotGentz sidebar. Click "Scan page for model numbers" to extract model numbers, brand, and category from the current page. The results panel shows detected model numbers with "Manual" and "Support" buttons for each model. Click "Manual" to search for the PDF manual, or "Support" to go to the brand's support page. Use "Save" to store the model number for future reference. Use the manual search section to enter a model number and brand manually. The saved appliances section shows all saved models—click the document icon to search for a manual, or the X to delete. The script auto-scans pages on load.

THE TECHNICAL MECHANISM

This script uses regex pattern matching to detect model numbers from page text. Four patterns capture common formats: letters+numbers (ABC123), letters+numbers with separators, numbers+letters, and complex alphanumeric combinations. The script filters out false positives (short strings, all numbers). Brand detection uses a list of 20+ major appliance brands. Category detection uses a list of 15+ appliance types. For each brand, the script maintains support and manual search URLs. When a model number is detected, the script generates a manual search URL (brand-specific manual page or Google search) and a support URL. Saved models are stored using GM_setValue with model, brand, category, and date. The interface is built using BGPanel with sections for results, saved models, and manual search.

THE PANEL

The panel is draggable anywhere on the screen and remembers its position between sessions. It can be collapsed to a small floating bubble to minimize distraction, and expanded again with a single click. The panel's width can be adjusted, and pressing the Escape key closes it instantly. All settings and saved models are persisted locally using GM_setValue, so your data remains intact across page reloads and browser restarts.

PLEASE NOTE

This userscript requires the free BotGentz extension to function. The script extracts model numbers from page text—it may capture false positives or miss some model numbers. Review the detected models before using them. Brand-specific URLs are provided for major brands—for brands without specific URLs, a Google search is used. The script does not access external APIs or store any data outside your browser. No data from your browsing is stored or transmitted anywhere—all processing occurs entirely in your browser.
