What the prompt labels mean

These are the person's own words, as shared in the source.

Create a 5-day weeknight dinner plan for a UK family of 5 (two adults, three teenagers). Budget is around £60-70 for the week’s dinners. One person doesn’t like mushrooms. Cooking time must be under 45 minutes per meal. We have a slow cooker and an air fryer. Maximise ingredient overlap between meals to reduce waste. Include a shopping list at the end, grouped by supermarket aisle.

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: Plan a week of family dinners that fits our budget, tastes and what's already in the kitchen.

Questions to ask me first:
- How many people are eating, and what does each person refuse to eat?
- What's the weekly dinner budget and the time limit per meal?
- What do we already have in the fridge, freezer and pantry?

Inputs (fill in or confirm):
- Family: [NUMBER / AGES]
- Dislikes and allergies: [LIST]
- Budget: [AMOUNT PER WEEK]
- Time limit and equipment: [MINUTES / SLOW COOKER / AIR FRYER]
- Already have: [PANTRY AND FREEZER ITEMS]
- Meals we ate in the last two weeks: [LIST]

Rules:
- Reuse ingredients across meals to cut waste.
- Don't repeat meals from my recent list.
- Leave staples I already have off the shopping list.
- Don't give calorie or macro numbers unless I ask, and say they're rough estimates.

Checkpoint: Show me the five meal names and wait for my OK before writing recipes and the list.

If you get stuck: If the budget doesn't fit, tell me which meal to swap instead of quietly going over.

Verify before you finish: Check every recipe ingredient is either on the shopping list or on my already-have list.

Output: Five dinners with short recipes and a shopping list grouped by aisle with rough costs.

Done when: We have a week of dinners everyone will eat and a list that only has what we need.

Outcome

Mike, who writes Tech Dads Life, spent four months using ChatGPT and Claude to plan dinners for a UK family of five with three teenagers. A detailed prompt with a budget, a mushroom dislike, a 45-minute limit, a slow cooker and air fryer, and a request to overlap ingredients was the turning point: chicken bought for Monday's fajitas also covered Wednesday's stir-fry, and the shopping list was grouped by aisle. Claude was better at explaining choices, substitutions and using leftovers for lunch. The wins were variety, such as a Korean beef bowl the fussiest eater liked, less mental load and noticeably less food waste. The problems were real: the kids still rejected meals, repetition crept in by week three, the free ChatGPT tier forgot the family each week, the shopping lists assumed an empty pantry and took almost as long to edit as writing a list, and calorie and macro estimates were unreliable. The family settled on a shared "Family Meals" Google Calendar and now uses AI only once or twice a month for ideas.

Evidence: Described by posterThe person describes what happened in words, without screenshots or video.

Known limitations

PartialThe source says it only partly worked, or had a significant problem a person had to deal with.

What went wrong: Ideas and ingredient overlap worked, but meals repeated, kids rejected some, shopping lists ignored the pantry and macros were off; the family went back to a shared calendar.
