Universal Warranty Length Badge

WHAT IT DOES

This script automatically scans product pages for warranty information and gives you an instant, easy-to-read summary of what's covered and for how long. It extracts warranty duration in months or years, identifies the type of warranty (full, limited, lifetime, basic, extended), and captures key terms and conditions. A floating badge appears on your screen with a clear rating—Excellent, Good, Limited, or Poor—based on warranty length and coverage type. The badge also shows the duration, coverage type, and a snippet of the warranty terms, so you can quickly compare products and make informed purchasing decisions without hunting through fine print.

WHERE IT RUNS

The script works on any product page across the web—electronics retailers, appliance stores, auto parts sites, furniture sellers, and thousands of other e-commerce platforms. It runs on Amazon, Best Buy, Walmart, Home Depot, Newegg, and countless other sites. The script's multi-layer detection finds warranty information whether it's in dedicated warranty sections, product descriptions, technical specifications, shipping and returns policies, or FAQ sections.

HOW TO USE

After installation, the script scans automatically when you load a product page. Open the panel to customize your experience: toggle auto-scan on or off, control whether the badge appears, choose its position (top-right, top-left, bottom-right, bottom-left), and set custom colors for rating levels. Toggle warranty section highlighting to visually mark warranty content on the page, and control whether warranty terms are displayed in the badge. Click "Scan Now" to manually trigger a check after dynamic content loads. Click the badge itself to toggle its opacity for a less distracting view. All settings are saved and persist across pages.

TECHNICAL MECHANISM

The script uses a structured extraction pipeline to parse warranty information. First, it locates warranty-related content using a prioritized selector strategy targeting common warranty elements (.warranty, .product-warranty, .guarantee, .warranty-details) and falls back to text-based detection across product description containers. Second, it applies regex-based parsing to extract duration using pattern matching for months, years, and lifetime indicators. Third, it identifies warranty type by scanning for keywords like "full," "limited," "lifetime," "basic," and "extended." Fourth, it extracts relevant terms by capturing context around coverage-related keywords. The script then calculates a rating based on duration in months (120+ = excellent, 36-119 = good, 12-35 = limited, 1-11 = poor, lifetime = excellent) and type modifiers. All results are displayed in a persistent floating badge with color-coded feedback.

THE PANEL

The settings panel is fully draggable and can be positioned anywhere on your screen. It automatically snaps to the nearest edge when released, keeping your workspace organized. The panel can be collapsed to a small bubble showing only a gear icon, and restored with a single click. Its position is remembered across page reloads using GM_setValue. The panel also responds to the Escape key, which instantly hides it until you click the bubble again. All settings are saved immediately when changed and persist across browser sessions.

PLEASE NOTE

This script requires the free BotGentz extension to run. Warranty terms vary widely across products and manufacturers, and the script's parsing may occasionally misinterpret unusual warranty wording or miss complex conditions. Always verify warranty details with the official product documentation before making a purchase decision. The script does not access, store, or transmit any personal data, purchase history, or browsing information. All extraction and rating happens locally in your browser, and no information ever leaves your device.
