Loan Offer Comparison Summarizer

WHAT IT DOES

AI-powered loan offer comparison summarizer that compares loan offers and generates clear, plain-English summaries highlighting key differences and best-value recommendations. The script reads loan offer details from the current page—interest rates, loan amounts, terms, fees, monthly payments, total cost, and APR—and generates an easy-to-understand overview. The AI produces a comparison summary comparing costs, monthly payments, total interest, and identifying which offer may be the best value based on your priorities. You can customize the comparison focus (lowest monthly payment/lowest total cost/lowest APR), reading level, and toggle inclusion of fees, total cost, and monthly payment details. The user reviews the output before copying or using it.

WHERE IT RUNS

Works on all loan comparison pages (match pattern *://*/*), including mortgage comparison sites, personal loan platforms, auto loan pages, student loan comparison tools, bank product pages, and any page containing multiple loan offers.

HOW TO USE

Install the script and the Loan Offer Comparison Summarizer appears in the panel. Configure your comparison focus, reading level, and toggle inclusion of fees, total cost, and monthly payment details using the settings controls. Click "Compare" to analyze the current page. The AI extracts loan offer details and generates a plain-English comparison summary. Review the output in the panel. Click "Copy to Clipboard" to copy the comparison for decision-making or sharing with a financial advisor. Adjust the settings and regenerate if you want a different focus or level of detail.

REAL MECHANISM: DOM CONTENT EXTRACTION WITH AI LOAN COMPARISON SUMMARIZATION AND REVIEW GATE

This script uses a hybrid extraction approach that prioritizes structured content when available. First, it checks for WebMCP (navigator.modelContext), a W3C proposal that exposes structured tools on the page. If available, it calls getContent() to obtain structured loan data. If WebMCP is not present—the common case today—it falls back to DOM scraping using targeted selectors for loan comparison sections (loan-offer, comparison-table, loan-comparison, offer-details, loan-terms, apr-display, monthly-payment, and total-cost). It also scans table structures for loan-related keywords (apr, rate, fee, monthly payment, interest, term, loan amount, total cost, closing cost, origination fee) and extracts relevant content from paragraphs, list items, table cells, and headings. The extracted text is sent to an AI backend via GM_xmlhttpRequest, which processes it with a system prompt that includes the user's comparison focus, reading level, and inclusion preferences. The AI returns a plain-English comparison summary (up to 250 words) comparing costs, monthly payments, total interest, and identifying the best value offer. The response is displayed in a bordered container for review before copying. Copy-to-clipboard uses GM_setClipboard. All settings (comparisonFocus, readingLevel, includeFees, includeTotalCost, includeMonthly) are persisted via GM_setValue. The script enforces a review-before-use pattern: the user must read and approve the AI output before copying it.

THE PANEL

Drag the panel anywhere on screen by clicking and holding the header. It snaps to screen edges when released. Collapse it to a small bubble by clicking the minimize button, and expand it back by clicking the bubble. Resize the panel from any corner. Press Escape to close the configuration panel. Your position and size preferences are saved automatically per site.

PLEASE NOTE

This script requires the free BotGentz browser extension and an active AI subscription for the summarization service. AI-generated comparisons should be reviewed for accuracy before use—the AI may misinterpret loan terms or omit important details. The script reads the current page content and sends it to the AI backend for processing; no data is stored or logged. Websites change frequently; if the script stops detecting loan content, check for updates to the extraction selectors.
