/// Bill → audit → appeal
Snap it. See the errors. Draft the appeal.
A drafting aid — not legal, medical, or financial advice. No outcome guaranteed.
/// The problem
A wrong bill shouldn't require a paralegal.
Understanding a confusing medical bill or fighting a denial usually means becoming a billing expert overnight — or pasting private documents into a chatbot and hoping. Overturn makes it a guided, guardrailed workflow instead.
Bills are deliberately opaque
Codes, allowed amounts, and out-of-network charges are hard to read — which is exactly how errors slip through.
Denials feel final
Most people never appeal, because they don't know they can or don't know where to start.
Chatbots aren't private
The usual workaround — paste it into a general AI — sends your name, member ID, and diagnoses to someone else's server.
/// What Overturn does
Guided, guardrailed, and on your side.
From a photo of a bill to a professionally structured appeal — built only from your facts.
Capture on-device
Photograph a bill, Explanation of Benefits, or denial letter and Overturn reads it right on your iPhone.
Free audit
It flags possible problems in plain English — duplicate charges, amounts over your plan's allowed rate, surprise out-of-network bills, coding errors — each with a confidence level and why.
Draft an appeal
Turn the issues into a personalized, professionally structured appeal letter built only from your facts. Edit it and export a PDF to send yourself.
Track & escalate
Reminders keep your appeal deadline in view, and Overturn can draft the next-step letter if you're denied again.
Private by design
Bills are read and stored only on your device. When AI is used, your name and member ID are removed first — our servers never see your documents.
Honest by design
It never invents diagnoses, amounts, or legal citations, and it explains your rights in plain language. A drafting aid, not advice.

/// FAQ
Good questions.
Is Overturn legal or medical advice?
No. Overturn is a drafting and organizing aid — not legal, medical, or financial advice, and no outcome is guaranteed. It doesn't file appeals or contact your insurer for you; you stay in control the whole way.
Are my medical documents private?
Yes. Your bills are read and stored only on your device. When AI is used, your name, member ID, and other identifiers are removed first, so our servers never see your medical documents.
What does it actually catch?
Duplicate charges, charges over your plan's allowed amount, surprise out-of-network bills, coding errors, and more — each flagged with a confidence level and an explanation of why it might be wrong.
Read the bill. Draft the appeal. Keep it private.
Snap a bill or denial and let Overturn find the errors and help you push back — on your device, in your control. Available now on the App Store.
