A SaaS platform that takes users' financial inputs (credit score, income, debt, down payment, potential cosigner details) and generates personalized auto loan recommendations. The tool predicts APR ranges across multiple lenders, advises on optimal loan structure, evaluates whether refinancing makes sense, calculates the cosigner impact on rates, and provides actionable next steps. Integration with lending partners enables real-time rate quotes based on the user's specific profile.

Auto loan rates remain elevated post-pandemic, making optimization critical for borrowers. Rising adoption of fintech tools and open banking APIs makes real-time rate comparison and personalized lending analysis technically feasible and expected by consumers.
