How it works

What the AI does, and who answers for it

You never deal with the AI. We do. Every dollar figure in TrueK is worked out by ordinary software from your own sales and your own supplier bills; the AI chooses what is worth telling you and writes it in plain English. If a figure is wrong, that is ours to fix, and we say so in the next report. Here is what the AI actually does, and what stops it doing anything else.

One rule, and everything else follows from it

The AI may only speak in numbers the code worked out and handed it. It chooses which facts matter to your week and writes them in plain English. It never works a figure out itself.

That is not a preference. A number in a report has to be reproducible and testable, and a number worked out in a model's head has no test that can hold it. So the arithmetic is code, with hand-checked examples behind it, and the AI is the writer.

"A 50¢ lift on the flat white at current volume is worth about $5,070 a year. Volume would need to fall 9% to erase it."
Every figure in a sentence like that is calculated, checked and traceable back to the invoices it came from. The AI decided it was worth your Monday.

The order of work

Six checkers, an analyst, a reviewer. And you.

TrueK runs like a small finance firm. The checkers are pure arithmetic: they read every sale and every supplier bill, and they cannot guess. The analyst turns what they find into plain English. The reviewer can stop the send. You decide what to do about it.

  1. Six checkers · pure arithmetic, no AI

    The price checkerevery invoice price against what that supplier has been charging you
    The bill auditorcosts that cannot be right, and bills that arrived twice
    The usage checkerwhat your recipes say the week should have cost, against what you bought
    The movement checkerchanges big enough to be worth your time, and the ones that are not
    The supplier checkera supplier creeping up month on month rather than all at once
    The data health checkerhow much of your spending we can actually see

What stops it

Every number is checked back against the working

Before anything is sent, each number in what the AI wrote is matched against the numbers it was handed. One digit that did not come from the arithmetic and the whole passage is thrown away. The plainly written version the code produced is sent instead, so the check can only ever cost you some polish, never a figure.

A number that cannot be traced back to an invoice is not printed. That is the whole rule, and it fails towards saying less.

It suggests; it is not allowed to instruct

Every finding has the same shape: what happened, what it is worth in dollars, what would have to change to cancel it. When the numbers in front of it back an obvious option, it may say so, as an option offered, never an order given. Wording that strays into instructing you is blocked before the email goes out, by a check that reads the finished text.

You run the cafe. You know which regular would notice a 50 cent rise. That is why a suggestion always arrives with the working that produced it, and why it never promises what a change will earn: it shows the arithmetic under a stated assumption, and that is all an honest number can do.

The AI never learns who you are

What goes to the model is numbers and findings. Your cafe's name, your name, your address and your contact details do not. It processes in Sydney, in the same region your data is stored, and nothing you connect is used to train anybody's model.

The AI is our responsibility, not yours

We do not hand you a model and leave you to check it. TrueK runs the AI, tests what it writes against the arithmetic, and answers for what it sends. A wrong figure is corrected in the next report and named as a correction, not buried. That is part of what you pay for.

A person reads every report during the pilot

Nothing reaches a founding cafe's inbox until the founder has read it and verified the figures himself. If the AI is unavailable or its wording fails a check, the report still arrives: written by the software, in the same plain style, with the same numbers.

What is not built yet, and what never will be

A quarterly review: next

A whole quarter read at once, and what TrueK caught in it. It is planned, not built. Founding cafes do not get it today. It is made of the weekly Keeps it reads, so it arrives once a cafe has a quarter of them.

Labour, per item: a choice

We flag an item as high-prep and we will not put a dollar figure on the minutes. Splitting a wage bill across plates would be a guess, so we do not do it.

Anything that writes back: a promise

TrueK reads. Nothing in it, the AI included, is connected to anything that writes back.

Still want to know how a figure was worked out?

Ask, and you get the arithmetic, not a summary of it.
