Not a chatbot with opinions.
Ask the same question about the same bill. One guesses. One reads your documents, remembers your case, and cites the law it stands on.

What Tyndale checks
Built to read the fine print for you
Not a chatbot with opinions — an audit of your actual bill against your actual coverage, with sources attached.
Every line, in plain English
Procedure codes, modifiers, adjustments — each line item on your bill is translated into words you actually use, and verified against the care you received.
Checked against real prices
Each charge is compared to your plan benefits, Medicare rates, and the prices your hospital and insurer publish — not a generic average.
Findings you can verify
Every finding cites its source — the plan clause, the rate, the published price — so you can check the work before you pick up the phone.
A plan, not just a report
Phone scripts, dispute guidance, and concrete next steps for each finding, so you know exactly who to call and what to say.
Your documents. Your rules.
Medical bills are some of the most personal documents you have. We treat them that way.
Encrypted, always
Your documents are encrypted in transit and at rest.
Never sold
We never sell your data — not to insurers, not to advertisers, not to anyone.
You decide
Nothing you upload is used to improve Tyndale unless you say so — a consent toggle in your settings keeps that choice in your hands.
Tyndale is an advocacy tool: it helps you understand and question your medical bills. It does not provide medical, legal, or financial advice.

Tyndale is just getting started
Every bill Tyndale sees makes it sharper.
We're early — and more errors caught means more people helped. Fix your bill, and you make the next person's fight easier too.
Our story
We started Tyndale after watching people we love overpay bills that were simply wrong. Insurers automate denials; hospital billing works for the hospital. We’re the only party in the room with no reason to lie to you.
