The question that runs
What does this card machine actually cost me? Read these statements and put what you find in a document I can read.
Word for word, the one from the video. It goes in exactly as written — no steps, no method, nothing telling it where to look.
Example data · Real analysis
What it found in a folder it had never seen
- Found the three rises buried in the statements — April 2024, September 2024, February 2025 — by comparing every monthly “rate applied” line against the contract.
- Read article 6 of that contract and explained why they hold anyway: thirty days’ notice, given in the statement itself, and silence counts as acceptance.
- Noticed a PCI compliance fee that appears in no contract, running quietly since June 2024.
- Worked out on its own that the two August dips in volume are the annual closing — fixed fees on a near-empty month, which is what inflates the rate.
- Checked its own arithmetic against the till journal, to the centime, and said so: the statements are correct. The problem is the pricing, not the accounting.
The wine cellar is invented, and so are its 24 statements — this is example data, built so the answer could be checked against the truth. Everything else is real: real files in a real folder, read by the app on a Mac, and no hint of where to look or what to find. There are no customers to quote here yet. When there are, they will speak for themselves.

What to bring
Your card-terminal statements — as many months as you kept — and the contract if you still have it.
Not on your Mac? They are usually one export away in your provider’s online portal: download the months you can, drop them in a folder, start there.
What happens then
- You show it where the documents are. A folder on your Mac. Nothing is uploaded to us, and there is no account to make.
- It reads them, and you watch it work. The run above took 14 minutes 52 seconds and that time is visible, on purpose. It is reading every line of every statement, which is the part nobody does by hand.
- You get a document. A page that opens in your browser: the number, how it got there, and which file each figure came from. Print it, or save it as PDF with ⌘P and send it to your accountant.
Your files stay on your Mac and we never see them. Claude reads them, and what it reads goes to Anthropic to be processed — exactly as it would in a terminal with no app of ours in between. The long version is in the privacy policy.
Same question. Your statements.
