As of 13 August 2026, AI can plan your meals on a budget.
Most people should hand this to a purpose-built tool.

What the alternative costsEat This Much is a purpose-built meal-planning tool, but no price is provided in the available tool information.
If this goes wrong, the plan can exceed your budget or include an unsuitable ingredient, and an allergy or medically important dietary error can cause harm.

Do it yourself
Second choiceA chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.
How to actually do it
- Open a note or spreadsheet and record the number of people, number of days, total budget, supermarket, dietary requirements, allergies, disliked foods, cooking equipment, available time and ingredients already at home.
- Open your supermarket's current online shopping pages or collect current prices for the foods you are willing to buy, then copy the product names, pack sizes and prices into the note.
- Paste the prompt into ChatGPT, Claude or Gemini and replace every bracketed slot with your household's information.
- Paste the ingredient and price list below the prompt, then ask the chatbot to produce the plan, recipes and grouped shopping list.
- Compare each estimated cost with the current product price and pack size in your note, and remove or replace any item that takes the total over budget.
- Check every recipe against the allergy information and the current packaging labels before buying or cooking, including sauces, stock, snacks and prepared foods.
- Save the final plan and shopping list, then adjust portions and leftovers after checking what you already have and what your household will actually eat.
Prompt
Plan affordable meals for [number of people] for [number of days]. My total food budget is £[amount], and I shop at [supermarket or shops]. Use only the prices and product information I provide, and say clearly when a price or fact is missing instead of guessing. We have these dietary requirements and allergies: [list them]. We do not eat: [ingredients or foods]. We have this cooking equipment: [list]. We have this available time on weekdays and weekends: [details]. We already have these ingredients: [list]. Create a practical meal plan with breakfast, lunch, dinner and suitable snacks where relevant. Reuse ingredients to reduce waste, include portions and simple instructions, and make a shopping list grouped by shop section. Show the estimated cost using only my supplied prices and keep it within the budget. For every meal, list the ingredients that could contain an allergen and tell me to check the product label. Do not diagnose, treat or manage a medical condition, and do not present the plan as medical advice. If I mention worrying or urgent symptoms, tell me to contact NHS 111 or use 111.nhs.uk instead of answering with a diet plan. Ask up to five essential questions before planning if the information is not sufficient.
Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.
Hand it to a person
The distant thirdA person who owns the outcome does this end to end, worth it when the failure is dear.
What it gets wrong
- AI cannot know current supermarket prices or stock unless you provide reliable, current information.
- AI cannot guarantee that a product is safe for an allergy, so you must check the packaging and cross-contamination information.
- AI cannot decide whether a diet is suitable for a diagnosed condition, pregnancy, eating disorder or other medical need.
- AI often treats stated preferences as fixed facts and misses household habits, cultural expectations or appetite unless you describe them.
- AI can make arithmetic, portion and food-waste errors that leave the plan over budget.
Even on a YES, the friction has a name: stakes of error, real time truth and context depth.
How we scored this
Five axes, each scored nought to two by hand: ten means AI carries the task cleanly, and the thresholds that turn a total into YES, PARTLY or NO are published in the methodology. Each axis name links to its definition.

| Output | 2 |
| Inputs | 2 |

FAQ
- Can AI plan meals on a budget?
- Yes. It can turn your budget, household details, ingredients and supplied prices into a meal plan and shopping list, but you need to check the current prices, portions and food labels.
- Can ChatGPT make a cheap weekly meal plan?
- Yes, if you provide the number of people, budget, supermarket, foods already at home and any dietary restrictions. Tell it to use only prices you provide, because it cannot reliably know current UK prices or stock.
- Can AI plan meals around allergies?
- It can suggest meals that avoid the allergens you name, but it cannot guarantee that a product or kitchen is safe. Check every label and cross-contamination warning yourself before buying or cooking.
- Is AI meal planning safe?
- It is generally useful for ordinary meal organisation, but do not use it to diagnose or manage a health condition. For urgent or worrying symptoms, contact NHS 111 or use 111.nhs.uk rather than relying on a meal plan.
