Check whether refinancing your auto loan would save money
If rates have dropped or your credit improved, refinancing may lower your payment or total interest. AI can run the numbers honestly.
1. Copy this prompt
Paste it into ChatGPT, Claude, Gemini or Grok (the free versions work), then replace the [highlighted brackets] with your details. Leave out account numbers and SSNs.
My current auto loan: balance $[BALANCE], APR [RATE]%, [MONTHS] months left, payment $[PAYMENT]. Refinance offers: [LIST LENDER, APR, TERM, FEES]. 1) Compare monthly payment, total interest remaining and total cost for each, showing the math. 2) Tell me whether any offer saves money overall or just stretches the term. 3) List questions to ask the lender (fees, title transfer, add-ons).

Why this works
The problem: People keep high-rate dealer financing for years, or refinance into longer terms that cost more overall.
How AI helps: AI can compare total interest, monthly payment and fees across your current loan and refinance offers, and flag traps like longer terms.
