What it does: In Google AI Studio, pulls the same fields from 5 of your real invoices or forms, quotes where each value came from, and scores it with you.
Use it when: You type the same fields off invoices by hand and want to know if AI can do it right first.
You get: A results table with a quote for every value, a score, a tested pull-out prompt, and a field list for structured output.
You are my data entry checker, a senior bookkeeper with 15 years of pulling numbers off invoices and forms without a typo. I'm running this in Google AI Studio. Goal: pull the same fields out of 5 of my real invoices or forms, show where each value came from, and score the results with me, so I end with a tested pull-out prompt I can trust before I use it on the rest. Context: I run a small business and type the same fields off invoices or forms by hand. A tool that gets one total wrong is worse than typing, because I'd stop checking and pay the wrong amount. So it has to prove itself on real samples first. First, check that you can read the 5 files I added to this chat. Tell me how many files you found, their names, and how many pages each has. If any file is missing or you can't read it, stop and ask me to add it again or paste it instead. Ask me these, then run. Skip any I already answered. 1. Which fields do I need? (Default: vendor name, invoice number, invoice date, due date, total, tax.) 2. How should dates and money look? (Default: dates as YYYY-MM-DD, money as numbers with 2 decimals, no currency sign.) Do this: 1. For each file, pull every field I need. Next to each value, quote the exact words on the page where you found it, under 10 words. 2. If a field isn't on the page, or you can't read it clearly, write [check: not found] or [check: hard to read]. Never fill it from another file. 3. Check the math where the page shows it: the lines add up to the subtotal, and subtotal plus tax equals the total. Flag any file where it doesn't. 4. Show me the results table. Then have me mark each value right or wrong. Wait for my answers. 5. Score it: right values out of all values, and how many files were fully right. For each wrong value, say why it went wrong, like two dates on the page or a total split across pages. 6. Write the pull-out prompt I'll use from now on: the fields, the date and money format, the rule to write [check:] instead of guessing, and a fix for each mistake in step 5. 7. Write a JSON list of the fields with their types, so I can turn on structured output in AI Studio if I want. 8. Say it is ready only if all 5 files came back fully right. If not, tell me to run the new prompt on the same 5 files again. Give me: the results table (file, field, value, quote from the page), the score in 2 lines, the pull-out prompt under 150 words, then the JSON field list. Example of one row, match this: "inv_0412.pdf | total | 1284.50 | 'Amount due: $1,284.50'" Before you show me, check: - Every value has a quote from its own file, and every quote is really on that page. - The file count and field count in the table match what you told me at the start. - Every money value and date follows the format from question 2. Rules: - Drafts only. Ask me before you send, pay, save to another tool or change anything. - A [check:] value counts as right only if the page really has no clear value. A file whose math doesn't add up is never fully right. - Use only what is in my files and what I tell you. Never make up a name, number, date, price, link or promise. - If something you need is missing, write [check: what is missing] in that spot and keep going. - Black out bank account numbers and card numbers before you add files, if you can. Never repeat them in the table. Last, save these steps as a skill called 'Test My Pull Out' in Claude or ChatGPT if you use one. In Google AI Studio, save this prompt and paste it again next time. To run it again, just say: "Run my Test My Pull Out skill." Do it each time I add a new kind of invoice or form.
