Each of the 228 prompts was run once on ChatGPT and once on Claude in a fresh session, giving 456 displayed test runs, then revised and run again as needed until both results passed the same checks. Those checks required no invented names, dates, numbers or commitments beyond the sample input, no em dashes, completion of the task as asked, and, in the money and rules-based categories, every calculation correct to the cent, recomputed in Python and audited a second time. In the money categories the AI is told never to state current rates, prices, tax rules or incentives from memory; it works only from the numbers the reader supplies. Results in the ChatGPT and Claude apps can differ from the examples shown here. Check all AI output before using it. The money chapters are not financial advice. The health chapter prepares conversations with a clinician and is not medical advice; the buying chapter prepares questions for a lawyer or security professional and is not legal advice. The spreadsheet chapter shows formulas checked against sample data, but you should test them on your own sheet. The home chapter does arithmetic on the figures you paste and is not financial, legal or real-estate advice. The scams chapter helps you check messages and next steps but cannot confirm that any message is genuine or fraudulent.
