🚀 DetectHiddenFees — AI Contract Review That Finds Hidden Fees & Negotiation Leverage

👋 Hey Product Hunt community!

I built DetectHiddenFees — an AI contract review tool that scans contracts, invoices, and estimates to find hidden fees, pricing risks, and negotiation opportunities. Whether you're reviewing an AI construction contract, a contractor estimate, or a simple service agreement, hidden costs are buried in fine print.

The problem: Most people sign contracts without fully understanding them. They lose negotiation leverage before they even start the conversation. Hidden fees cost consumers billions every year — in construction contracts, auto financing, medical bills, and banking statements.

How DetectHiddenFees works:

1. Upload any contract, estimate, or proposal

2. AI scans for hidden fees, pricing risks, and unclear clauses

3. You get a clear report with specific negotiation questions to ask before signing
