Every Sunday evening, the same question comes back around: what are we eating this week? You open the fridge, jot down two or three ideas, forget half the ingredients at the store, and by Wednesday you end up ordering a pizza. Artificial intelligence solves this headache in a few minutes. You give it the number of people, your constraints (time, budget, allergies), and it hands you seven balanced dinners with a grocery list sorted by aisle.
In this guide, you'll discover three concrete ways to build your weekly meal plan and an automatic grocery list: first with the Skilzy AI Lab, then with a free assistant like ChatGPT, and finally with dedicated meal-planning apps. Each method is explained step by step, with the exact prompt to copy. You don't need any technical skills — just the ability to write down what you want to eat.
Why plan your weekly meals with AI?
Planning your meals with AI saves time and money and cuts down on waste: in a single request, you get balanced menus and a complete grocery list, instead of improvising every night. It's the difference between thirty minutes of thinking spread across the week and five minutes done once and for all.
Waste is a real expense. According to ADEME, each person in France throws away nearly 30 kg of food per year on average, and part of that comes from poorly planned purchases. When you head to the store with a precise list, built around recipes you'll actually cook, you buy less and you throw away less.
AI also helps you add variety and keep things balanced. You can ask it to alternate between meat, fish, legumes, and vegetarian dishes, following the broad principles of the official nutritional guidelines from the Manger Bouger program. In short: you delegate the tiring part (coming up with ideas, making the list) and keep the pleasure of cooking.
Method 1: generate your menus and grocery list with the Skilzy AI Lab
The simplest way to build your menus and grocery list is the Skilzy AI Lab: you pick a guided agent, answer two or three questions, and it writes everything for you. No blank page, no prompt to dream up — the tool asks you the right questions in the right order.
In the AI Lab, go to the Home tab, then to the Guided section. There you'll find a catalog of mini agents, each designed for a specific task. You pick one, it asks for the number of people, your constraints, and your cravings, then it sends back a complete menu and its grocery list.
The appeal of the Lab is that you use real AI tools directly inside the platform, with credits included, without piling up subscriptions. Skilzy is a French platform for learning and using AI day to day, and organizing meals is just one example of what you can automate once you get the hang of it. If you want to see everything that's covered, take a look at the different Skilzy programs: writing, images, automation, and plenty of other practical uses.
Good news if you just want to try it out: you can test it without a credit card. The discovery demo gives you 7 days with 1 image, 1 video, 1 track of music, and 10 messages. That's more than enough to generate a first weekly menu and get a feel for it. You just need to create an account — no card required.
Method 2: use a free AI assistant like ChatGPT
A free AI assistant like ChatGPT does the job too: you open a conversation, paste your prompt, and get your menus back in a single reply. It's the all-purpose option, handy if you already use the tool for something else.
The process is simple. You open a new conversation, write your request (you'll find a complete prompt template further down in this article), and get seven dinners with the list of ingredients. If a dish doesn't appeal to you, you reply „swap Thursday for a vegetarian dish" and the AI fixes just that one line.
Two limitations to keep in mind. First, the free version can be slowed down or restricted during peak hours. Second, if you're just starting out, writing a good prompt on the first try isn't obvious — which is exactly what a guided agent does for you. If you've never used the tool, start with our guide on how to use ChatGPT when you're a beginner; you'll save time.
Method 3: dedicated meal-planning apps
Specialized apps like Jow, Frigo Magic, or Mealime offer ready-made menus and generate a grocery list linked to delivery. They're useful if you want a catalog of already-photographed recipes and a cart that fills itself at your supermarket.
Their strength is integration. You pick your dishes, the app calculates quantities based on the number of diners, and sends the list straight to an online grocery service. Some even read the contents of your fridge to suggest anti-waste recipes.
Their limitations, though, are real. You're locked into the app's catalog: it's hard to step outside a specific recipe or impose an unusual constraint (a very tight budget, a special diet, an ingredient you need to use up). Many also work on a separate subscription, and some features are reserved for the paid version. A general-purpose AI assistant stays more flexible: you talk to it in your own words, and it adapts.
The right prompt for a successful weekly menu
A good prompt for a weekly menu fits in one precise sentence: number of people, days involved, budget, dietary constraints, and prep time. The clearer you are, the better the result. Here's a template to copy and adapt:
Put together a menu for the 7 dinners of the week for 2 adults and 2 children. Budget around 70 dollars. No pork, at least one vegetarian dish. Each recipe should take under 30 minutes to prepare. At the end, add the complete grocery list, with quantities, sorted by aisle (fruits and vegetables, fresh products, pantry, frozen foods).
A few tweaks that change everything:
- Specify the time available: „under 20 minutes on weekdays, a longer dish on the weekend."
- Mention what you already have: „I have zucchini and rice to use up."
- Ask for sorting by aisle: your list becomes usable as-is at the store.
- Add a variety constraint: „not the same starch twice in the week."
Knowing how to phrase this kind of request is a skill that will serve you everywhere. If the topic interests you, our guide to learning AI as a beginner covers the basics of writing clear instructions.
Adapting menus to your family and budget
AI adapts menus to your situation in seconds: allergies, a tight budget, picky kids, or express meals — just spell it out in your request. You don't get a generic menu, but a plan built for your household.
A few concrete cases. Tight budget? Ask for a „menu under 50 dollars for the week, prioritizing legumes and seasonal vegetables." Kids who scowl at vegetables? Specify „recipes that appeal to children, with the vegetables mixed into the dish rather than served on the side." A surprise on Tuesday? Reply „Tuesday I get home late, suggest a dish under 15 minutes" and the AI recalculates just that day.
This logic of delegation applies to the whole family routine. The same reflex (give clear context, let the AI suggest, adjust) works, for instance, to help your child with homework without giving them the answers. Once you've grasped the principle with meals, you'll reuse it everywhere in your week.
Conclusion
Planning your meals and grocery list should no longer cost you your Sunday evening. With a guided agent from the Skilzy AI Lab, you get a balanced menu and a list sorted by aisle in five minutes, without knowing how to write a single prompt. A free assistant or a dedicated app do the job too, each with its own limits. The simplest thing is to give it a try: the Skilzy discovery demo lets you test without a credit card, long enough to generate your first menu and see whether the time savings win you over.
