Does it need the Shopify connection?

No. Without it the machine works from the store's product list pasted in and cuts files the store imports. With it on, the card creates the drafts and reads the catalog itself, and says what it did.

Will it publish for me?

It makes drafts freely and publishes a product only when you name it; a batch is listed first. That is the law on the face.

Where do prices come from?

From you, on the ladder or off it. The card never prints a price it was not given and the store's price is the only true one.

Can it attach the files?

No — that door is the app's and yours. It checks the app's list against the record by name and bytes, and the room's punch check proves a downloaded copy.

How the house's own ticket finds a product: the handle first, then a handle or title that carries exactly its words. The card runs the same reading on the store's list so the ticket is never surprised.

No. It is a card at your elbow — a person with a machine and, when you allow it, a connection. It stores nothing, runs no server and holds no key of its own.

What it is.

Thought partner for a demographer, at the standard the field sets for itself. It makes a data assembly, rates with denominators, a projection with assumptions, standard tables and a report with limits, by the field's own method: the standard: denominator shown, vintage recorded, assumptions printed.

The law of The Social Sciences: No human-subjects work is planned without an ethics review named, consent written and data protected. No card profiles or scores a named person. Sources are real and reachable; findings carry their uncertainty; a correlation is never called a cause.

Its laws, written into the card.

The standard: denominator shown, vintage recorded, assumptions printed.
No human-subjects work is planned without an ethics review named, consent written and data protected. No card profiles or scores a named person. Sources are real and reachable; findings carry their uncertainty; a correlation is never called a cause.
The researcher owns the claim; the card structures, drafts and checks.

How it works, once your AI has it.

Nº 714 PROPOSED · ONE PAYMENT

Sold as is under the term printed. A card instructs an AI you operate; results depend on your model, your files and your judgement. Not legal, tax, medical or financial advice. The terms →

ONE PAYMENT · NOTHING RENEWS ITSELF

OFFLINE · ONE LICENCE · PUNCH-CHECKABLE · THE STANDARD

One payment. The file is yours to keep and keeps working at its edition; new editions issued in the year after you buy reach you by email as replacement files. Tax is added at checkout where it applies. Nothing auto-renews.

ONE PAYMENT — NOTHING RENEWS ITSELF. CHECKOUT IS SHOPIFY’S OWN; YOUR CARD COMES BY EMAIL AFTER IT.
