Start here — the free check

One bill. Three minutes. Every finding shown with receipts.

No hunting through portals, no hold music. Snap a photo or upload a PDF and MBR does the reading.

1

Upload your bill

PDF or a phone photo. MBR reads every line, every code, every dollar — and if you were sent a summary bill with no detail, it drafts the letter that makes the provider itemize it.

2

Get provable findings

Arithmetic that doesn't add up. Duplicate charges. Preventive care billed to you. Every finding quotes the exact line it came from — math you can check yourself, not an AI's opinion.

3

Act on them

One click drafts the dispute letter — professional, specific, ready to sign and mail. Then add your EOB and MBR cross-checks what insurance says you owe against what the provider is billing.

Why not just a checker?

Medical billing doesn't happen in a day.
A one-shot checker forgets you in one.

Your bill and your EOB never arrive together. EOBs get reprocessed and corrected — sometimes more than once. The whole thing plays out over months, and the person with the complete paper trail wins. Here's what one routine bill actually looks like:

Day 1

The bill arrives

MBR checks it, finds a $45 duplicate charge, and files it — nothing to compare against yet.

Day 19

The EOB shows up

Weeks later, separately. MBR auto-matches it to the bill — insurance says you owe $120 less than the provider billed.

Day 33

The EOB gets corrected

Payers reprocess claims all the time. MBR saves the correction as version 2 — and keeps version 1, because the history is evidence.

Day 52

The provider re-bills

Same wrong amount. Your dispute letter — citing the claim number, both EOB versions, and the exact discrepancy — is one click.

Day 80

Resolved — in writing

Corrected balance, documented outcome, every document still on file if it ever comes back.

A tool that deletes your bill after 24 hours can't do any of this. By the time the EOB arrives, the fight is just starting — and your evidence is gone. MBR is built for how billing actually works: documents arriving out of order, numbers that change, and disputes that take 60–90 days to win.

Built on accuracy

Accurate enough to say "we're not sure."

Plenty of tools will tell you every bill is an outrage. MBR is built for the opposite: findings you can take to a billing office and defend.

🧮

Deterministic checks, not vibes

The core checks are arithmetic and pattern analysis on your bill's own numbers — provably right or they don't fire. A clean bill gets a clean report, and that's the point.

🏷️

"Unverified" is labeled, never hidden

Some things can't be proven from a bill alone — like whether a provider was in-network. MBR flags them, labels them unverified, and tells you exactly which document settles it.

💬

Denial codes, translated

CARC 45. RARC N130. Insurers speak in codes designed for other insurers. MBR translates every denial into plain English — what happened, why, and what to say when you call.

⚖️

The bill vs. what insurance actually said

The single most common overcharge: the provider bills more than your EOB says you owe. MBR matches them line for line and computes the exact disputed amount.

The command center

The system of record for your medical bills.

Everything above, running continuously for the whole household — so when a bill is wrong, you're not starting from a shoebox of paper.

📄Every bill and EOB, matched

Upload as they arrive — in any order. MBR pairs bills to EOBs automatically, tracks corrected versions, and surfaces every discrepancy, including EOBs that say you owe money with no bill in sight.

🔗Medicare, connected

Link Medicare and claims flow in on their own — no typing, no uploads. More insurers coming.

✉️Letters that get answered

Disputes, appeals, debt validation, itemized bill requests — drafted from your actual documents, with the reference numbers billing offices need.

⏰Deadlines, tracked

FDCPA response windows, appeal deadlines, follow-ups on requests that went quiet. MBR counts the days so you don't have to.

👨‍👩‍👧The whole household

Kids, parents, a spouse's specialist saga — one place for every family member's billing life, with deductible and out-of-pocket progress per person.

🚨Collections, handled

A collection notice is a legal clock. MBR reads it, tracks your 30-day validation window, and walks you through your rights step by step.

Trust & privacy

It's your health data. We act like it.

✓

Private by architecture

Your documents live in private, access-controlled storage. Row-level security means your account can only ever see your own data — enforced by the database itself, not just the app.

✓

U.S.-owned and operated

Built and run in New York. Your data is processed on U.S. infrastructure and never leaves the country.

✓

Delete means delete

Self-serve account deletion wipes your documents, your data, and your account — permanently, on your schedule, no support ticket required.

✓

You send every letter

MBR drafts; you review, sign, and mail. Nothing goes to a provider, insurer, or collector without your explicit attestation.

What we keep, and why — honestly

We keep your documents and the data extracted from them. That's not a bug — it's the product. Your EOB arrives weeks after the bill. Corrections arrive after that. A dispute takes 60–90 days. The paper trail is your leverage, and a tool that deletes it in 24 hours can't help you win.

We don't sell your data. No advertisers, no data brokers, no "de-identified datasets" quietly claimed for future commercial use. Your documents exist to serve exactly one party: you.

The full details are in our Privacy Policy — written to be read.
