App Maxxing: all 10 apps (Package of 10, early release)

EARLY RELEASE: PLEASE READ BEFORE BUYING

• These apps need your own OpenAI API key. They will not run without one, and a ChatGPT subscription does not include one.
• They are early releases that still need further testing. So far each app has passed our own offline tests, and has been run on its built-in sample against the live service on both models (October 2026). It has not yet been tried on a wide range of real files of different kinds and sizes. You may meet faults.
• Please tell us what you find after you buy: email kit376351@gmail.com with the subject "Maxxing feedback". Every report is read, and fixes are sent to buyers free.
• If we cannot get it running for you, email us within 14 days for a refund of the app price.

All ten App Maxxing apps in one download: ten checking tools for engineers and scientists, each built so that code does the checking and the AI is kept on a short lead.

• Spreadsheet Formula Checker
• Data Sheet Comparer
• Statistics Reporting Checker
• Revision Change Register
• Test Results Against Limits
• Reference List Checker

THE PRICE

Bought separately the ten apps cost $390. The package is $335. The code SAVE10 takes a further 10% off packages at checkout.

HOW IT IS BUILT

• The app's own code does the finding, the arithmetic and the unit conversions. The AI is used only for what code cannot do, and what it says is checked against your file.
• Anything the app cannot find in your file is marked "not found in the file", not trusted.
• The cost is shown before each run and after it, with a limit you set for one run.
• No verdicts: the app never says pass, fail or compliant. It shows you what it found and where.

WHAT YOU NEED

• Windows, Mac or Linux, and free Node.js 18 or newer
• Your own OpenAI account with API access and a key (platform.openai.com). This is separate from a ChatGPT subscription.
• You pay OpenAI for what you use, on top of the price of the app. What a run costs depends on the app and on how much you give it to read: each app shows the cost before every run.
• Eight of the apps use OpenAI's GPT-6 Astra model by default, and two use the cheaper GPT-6.1 Sol. In Settings you can switch between them.
• About ten minutes of setup. A step-by-step guide is included.

HONEST LIMITS

Each app does one job and works only from what you give it. None of them certifies or approves anything, and none replaces review by a qualified person. Each app's own listing describes its limits.

For educational purposes only, and for your own research and your own documents. The apps point things out for you to check: they do not certify, approve or sign off anything, what the AI writes can be wrong, and they are not a substitute for review by a qualified person. You are asked to accept this when you first open each app.

PRIVACY

The apps run on your computer. Each says before each run exactly what will be sent to OpenAI, under OpenAI's terms, and what stays on your computer; nothing is sent to us. Use it only with documents you are allowed to send to an AI service: not an employer's or customer's confidential documents, not export-controlled material, and not someone else's unpublished work. Your key is stored only on your computer and is sent only to OpenAI.

WHAT IS INCLUDED

Ten apps (ten zip files), start files for Windows, Mac and Linux, a sample to try, a setup guide and a README. Kitson Workshop is not affiliated with or endorsed by OpenAI.

REFUNDS

Digital download. If we cannot get it running for you, email kit376351@gmail.com within 14 days for a refund of the app price. Credit you bought from OpenAI is theirs to refund or not.
