How we make Promptpan cards

Who is responsible?

Haru operates Promptpan. Our About page explains the background and contact details. This page covers how we create, test and maintain cards.

AI drafts, human review

We use AI tools including ChatGPT, Claude and Codex to draft instructions, fields and usage notes. A human reviews the purpose, missing inputs, conflicting options and exaggerated claims, and decides what to publish. AI-generated examples also need review; one attractive example does not establish reliable reproduction.

What “we tried it” means

For image-card reproduction tests, we use the prompt a visitor would copy. We fill fields with the card's sample values and leave optional fields without examples blank. Photo cards use an input photo we have permission to use.

1. Submit the completed prompt unchanged to ChatGPT image generation, without adding quality instructions.
2. Compare wording, prices, dates, preservation of the photo subject, counts, layout, cropping and margins against the card's promises.
3. If the first result falls short, try once more with the same input. Keep failures as well as successes.
4. Record the full input, input photo, date, tool and any verifiable model information, attempt count, original outputs and assessment. Do not retouch or crop an output to make it pass.

This does not mean every card has completed testing. These are the standards for describing a card as tested, together with its observed scope, failures and limits. Tests using Codex's built-in image tool identify that tool and are not presented as direct tests on free ChatGPT. If model or settings equivalence is unverified, we say so. Image tests do not validate music, skill or video cards.

When we revise or remove a card

If results miss a core promise, we revise the fields, prompt or explanation and check again. We replace misleading examples or repeated failures, and withhold or remove cards with unresolved issues. We review expired seasonal and event cards to update or retire them. Error reports and changes to external services also trigger review.

Limits and permitted use

We cannot guarantee external AI results, free quotas, features or availability. Identical inputs can produce different results. Check names, prices, dates and usage rights before printing or publishing.

Do not use cards to impersonate real people, create unauthorized composites of them, or copy others' brands or logos without permission. Only supply photos, characters and text you have the right to use. Cards and AI outputs do not automatically resolve copyright issues. Read our Terms of Use.
