A prompt is the message you send to the AI tool. Copy the one on this page, put your own details where it asks, and read the answer before you act on it.

Recreated prompt

The source didn't share its exact prompt, so we wrote one from what it describes. The result shown is the source's, not ours.

What the prompt labels mean

The person didn't share their exact words, so we wrote this from what they described. We haven't tested it, and they didn't use this exact version.

You are our family meal planner. We are two adults, two toddlers and a nanny who cooks twice a week. We like Ottolenghi flavors, dinners under twenty minutes and the Feeding Littles approach. Each Saturday, look at the fridge photos I send, plan the week's meals, write the recipes, build a grocery list and make a printable PDF for the nanny. Only free-range meat from our trusted sources, and prefer large tubs over single-serve packs.

Optional stronger version

Our rewrite with extra checks. The poster didn't test it.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Turn fridge photos into a week of family dinners, recipes, a grocery list and a nanny-ready PDF.

Questions to ask me first:
- Who is eating, and which nights does someone else cook?
- What sourcing rules matter (meat, organic, brands, pack sizes)?
- How many minutes can dinner take on weeknights?

Inputs (fill in or confirm):
- Household: [ADULTS / KIDS / HELPERS]
- Fridge and pantry photos: [PHOTOS]
- Taste and feeding approach: [NOTES]
- Sourcing rules and trusted brands: [LIST]
- Store: [STORE]

Rules:
- Use what is already in the fridge first.
- Follow every sourcing rule; never swap in a cheaper meat or brand silently.
- Prefer one large pack over many single-serve packs unless I say otherwise.
- Keep weeknight dinners under the time cap.

Checkpoint: Show the week's meals and any sourcing doubts before building the grocery list.

If you get stuck: If an item can't meet the sourcing rules, list it as 'ask me' instead of substituting.

Verify before you finish: Check the grocery list against the sourcing rules and pack-size preference line by line.

Output: A 7-day meal plan, recipes, a grocery list by aisle and a printable PDF for the nanny.

Done when: I can place the order after a two-minute review with no surprise items.

Outcome

Magali Fiechter, a working parent with two toddlers, a dog and a nanny who cooks twice a week, added up five or six hours a week lost to grocery runs and dinner decisions. Fiechter built a ChatGPT custom GPT trained on the household: Ottolenghi flavors, dishes under twenty minutes and the Feeding Littles approach. Every Saturday it asks for fridge photos, plans the week's meals, writes recipes, builds a grocery list and makes a printable PDF for the nanny; a second agent fills the supermarket cart and flags it for payment. The first delivery brought factory-farmed chicken from Germany and ten tiny yogurts instead of one large tub, so Fiechter added rules on meat sourcing, what 'BIO' means at home and trusted brands. Within a few weeks it got things right, and what used to take six chaotic hours now takes fifteen calm minutes.

Context: The source calls the planner a custom GPT (a ChatGPT feature); the second agent that fills the cart is not named, so only ChatGPT is credited. The first order had misses before the rules were added. Self-reported time savings.
