About
Medical bills are confusing by design — and studies suggest most contain errors. Billy is the patient's advocate in your pocket. Snap a photo of any medical bill and Billy's AI reviews every line for the issues that quietly inflate what you owe.
WHAT BILLY DOES
• Scan any bill — Take a photo or pick one from your library. No typing, no forms. Billy reads the charges, codes, and amounts for you.
• Find potential errors — Billy's AI checks each line item for common problems: duplicate charges, upcoding, unbundling, balance billing, and amounts that look high against standard rates.
• Understand what it found — Each finding is explained in plain English, with the kind of supporting reference a billing department takes seriously.
• Dispute it — with one tap — Billy drafts a professional dispute letter citing the specific issues, and can print and mail it to your provider or insurer via USPS on your behalf. No envelopes, no stamps, no phone trees.
• Track every dispute — See what you've sent, when to expect a response, and record the outcome. Billy reminds you to follow up so nothing falls through the cracks.
• Escalate when needed — If a dispute is denied, Billy can help you draft an appeal or file a complaint with your state insurance commissioner.
BUILT FOR PATIENTS
• Private by design — Your bills are encrypted on your device. They leave it only to be analyzed, and are never used to train AI models.
• No account hassle — Sign in with just your email. No passwords.
• Free to scan — Scanning a bill and reviewing Billy's findings is free. You pay a one-time fee only when you choose to print and mail a dispute letter via USPS.
IMPORTANT
Billy provides informational analysis to help you communicate with your provider or insurer. It is not medical, legal, or financial advice, and it is not a law firm or a substitute for professional advice. Always review Billy's findings before acting on them.
Billy is available to U.S. residents 18 and older.
