Policy Compare
AI-powered policy comparison that helps regular people understand 50-page loan documents. Built after watching my parents lose hours to bank PDFs.
Case study
The problem
My parents were buying a home and got handed 50-page loan documents from three different banks. Nobody could read them. Every comparison site I could find existed to sell a specific card, not to help you understand what you were signing.
The approach
React and TypeScript on the frontend, Streamlit for the AI layer. Upload a policy PDF, get plain-language explanations of the jargon (floating rates, prepayment clauses, reset periods), and compare multiple policies side by side.
What worked
Around ten families have used it for real home-loan decisions. The common feedback: two to three hours saved per comparison, and for the first time they understood what they were signing.
What I'd do differently
I underestimated how much of the value was in the glossary, not the comparison. If I rebuilt it, I'd put the term-by-term explanations at the center and make the multi-doc compare optional.
More detail
A web app where anyone can upload loan policy PDFs and get plain-language explanations of banking jargon plus side-by-side comparisons across banks. Built in React and TypeScript on the frontend, with Streamlit powering the AI layer.
