Outcome

The Verge's Jay Peters asked Gemini Spark to draft an email to their spouse with the couple's average monthly grocery spending in 2026, without naming the spouse or saying where the budget was; the spreadsheet in Drive doesn't have 'budget' in its name. Spark found the spouse's email address, pulled the monthly grocery totals from the right 2026 spreadsheet (including May's incomplete data), averaged them and put a draft in Gmail that used the spouse's first name and a sign-off the couple use. Jay's reaction: 'Wow, that's actually nuts.' Their wider verdict was that Spark still needs checking and isn't worth the $99.99-a-month plan on its own.

Prompt Recreated prompt

The source didn't share its exact prompt, so we wrote this from what it describes.

Run this task now, exactly as written below. Everything you need is here, so start straight away and only stop if something required is missing or a rule below tells you to.

Goal: Work out our average monthly spending in one category from our budget spreadsheet and draft a short email about it.

Fill in before running:
- Where our budget spreadsheet is: [FILE]
- The category and months: [DETAILS]
- Who the email is for: [NAME]

You're not my accountant or financial adviser. Show your working, label estimates as estimates, and tell me which points a professional or the official source should confirm.

Rules:
- Use only the spreadsheet; show each month's total and the average.
- Say if the current month is incomplete, and give the average with and without it.
- Keep the email short and friendly, with the numbers in a small table.
- Save it as a draft and don't send it.
- If a site asks me to sign in, pause and let me do it myself (including any CAPTCHA or two-step code); never guess or store passwords.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.

Output: A draft email with the monthly totals and the average.

You'll know it worked when: the numbers match the spreadsheet and the email is ready to send.

Before you finish: re-read my goal and constraints, check your answer against each one, and list anything you assumed or couldn't confirm.

  • Nick Malham shares a Gemini prompt for turning six months of Gmail into one shared Google Sheet of household admin: insurances, banking and home loan, utilities, car cover, phone and internet, subscriptions, and will and power of attorney, with company, cover type, who it's for, account number, cost and frequency, payment type and key phone numbers. Malham suggests connecting Gemini to Google Workspace first, and checking a 12-month bank export for anything that never reached the inbox.

He says it removed duplicates, broke spending down by vendor and category, separated one-time and business expenses and built a realistic monthly budget, which he then went through with his three oldest kids to decide together where to cut.
